Languages in censuses

Many countries and national censuses currently enumerate or have previously enumerated their populations by languages, native language, home language, level of knowing language or a combination of these characteristics.

Languages in censuses. Map showing countries where the languages of people was enumerated at least in one census since 1991.

Afghanistan

Main article: Languages of Afghanistan

Pashto and Dari (Persian) are the official languages of Afghanistan; bilingualism is very common. Both are Indo-European languages from the Iranian languages sub-family. Dari has always been the prestige language and a lingua franca for inter-ethnic communication. It is the native tongue of the Tajiks, Hazaras, Aimaks, and Kizilbash. Pashto is the native tongue of the Pashtuns, although many Pashtuns often use Dari and some non-Pashtuns are fluent in Pashto.

Other languages, including Uzbek, Arabic, Turkmen, Balochi, Pashayi, and Nuristani languages (Ashkunu, Kamkata-viri, Vasi-vari, Tregami, and Kalasha-ala), are the native tongues of minority groups across the country and have official status in the regions where they are widely spoken. Minor languages also include Pamiri (Shughni, Munji, Ishkashimi, and Wakhi), Brahui, Hindko, and Kyrgyz. A small percentage of Afghans are also fluent in Urdu, English and other languages.

Algeria

The official language of Algeria is Modern Standard Arabic (literary Arabic), as specified in its constitution since 1963. In addition to this, Berber has been recognized as a "national language" by constitutional amendment since May 8, 2002. Algerian Arabic and Berber are the native languages of over 99% of Algerians, with Algerian Arabic spoken by about 72% and Berber by 27.4%. French, though it has no official status, is widely used in government, culture, media (newspapers) and education (from primary school), due to Algeria's colonial history and can be regarded as being a de facto co-official language of Algeria. Kabyle, the most spoken Berber language in the country, is taught and partially co-official (with a few restrictions) in parts of Kabylie.

Argentina

Dialectal variants of the Spanish language in Argentina

The de facto official language is Spanish, spoken by almost all Argentines. The country is the largest Spanish-speaking society that universally employs voseo, the use of the pronoun vos instead of tú ("you"), which imposes the use of alternate verb forms as well. Due to the extensive Argentine geography, Spanish has a strong variation among regions, although the prevalent dialect is Rioplatense, primarily spoken in the La Plata Basin and accented similarly to Neapolitan language. Italian and other European immigrants influenced Lunfardo—the regional slang—permeating the vernacular vocabulary of other Latin American countries as well.

There are several second-languages in widespread use among the Argentine population:

• English, taught since elementary school. 42.3% of Argentines claim to speak it, with 15.4% of them claiming to have a high level of language comprehension.
• Italian, by 1.5 million people.
• Arabic, specially its Northern Levantine dialect, by one million people.
• Standard German, by 400,000 people.
• Yiddish, by 200,000 people, the largest Jewish population in Latin America and 7th in the world.
• Guaraní, by 200,000 people, mostly in Corrientes, where it is official de jure.
• Catalan, by 174,000 people.
• French, including the rare Occitan language.
• Quechua, by 65,000 people, mostly in the Northwest.
• Wichí, by 53,700 people, mainly in Chaco where, along with Kom and Moqoit, it is official de jure.
• Vlax Romani, by 52,000 people.
• Japanese, by 32,000 people.
• Aymara, by 30,000 people, mostly in the Northwest.
• Ukrainian, by 27,000 people.
• Welsh, including its Patagonian dialect, in which 25,000 people are fluent. Some districts have recently incorporated it as an educational language.

Armenia

Armenian is the only official language. Due to its Soviet past, Russian is still widely used in Armenia and could be considered as de facto second language. According to a 2013 survey, 95% of Armenians said they had some knowledge of Russian (24% advanced, 59% intermediate) compared to 40% who said they knew some English (4% advanced, 16% intermediate and 20% beginner). However, more adults (50%) think that English should be taught in public secondary schools than those who prefer Russian (44%).

Australia

Although Australia has no official language, English has always been entrenched as the de facto national language. Australian English is a major variety of the language with a distinctive accent and lexicon, and differs slightly from other varieties of English in grammar and spelling. General Australian serves as the standard dialect. According to the 2011 census, English is the only language spoken in the home for close to 81% of the population. The next most common languages spoken at home are Mandarin (1.7%), Italian (1.5%), Arabic (1.4%), Cantonese (1.3%), Greek (1.3%), and Vietnamese (1.2%); a considerable proportion of first- and second-generation migrants are bilingual. A 2010–2011 study by the Australia Early Development Index found the most common language spoken by children after English was Arabic, followed by Vietnamese, Greek, Chinese, and Hindi.

Bahrain

Arabic is the official language of Bahrain, though English is widely used. Bahrani Arabic is the most widely spoken dialect of the Arabic language, though this differs slightly from standard Arabic. Arabic plays an important role in political life, as, according to article 57 (c) of Bahrain's constitution, an MP must be fluent in Arabic to stand for parliament. Among the Bahraini and non-Bahraini population, many people speak Persian, the official language of Iran, or Urdu, the official language of Pakistan. Malayalam and Nepali are also widely spoken in the Nepalese workers and Gurkha Soldiers community. Hindi is spoken among significant Indian communities. Many commercial institutions and road signs are bilingual, displaying both English and Arabic.

Belgium

Further information: Language legislation in Belgium

In the past, Belgium held a census each ten years, including a language census (nl/fr). Since 1932, the results of this census defined to which official language a municipality belonged (Dutch, French or German). However, this caused a lot of conflicts along the language border, in Brussels and its periphery (due to the Francization of Brussels). The territory of Belgium was consequently divided into four definitive official language areas and the language census was abolished, effective 1 September 1963. No national language censuses have been held since then.

Brunei

The official language of Brunei is Malay. The Ministry of Culture, Youth and Sports supports for a lingual movement aimed at the increased use of the language in Brunei. The principal spoken language is Melayu Brunei (Brunei Malay). Brunei Malay is rather divergent from standard Malay and the rest of the Malay dialects, being about 84% cognate with standard Malay, and is mostly mutually unintelligible with it. English and Chinese are also widely spoken, English is also used in business, as a working language, and as the language of instruction from primary to tertiary education, and there is a relatively large expatriate community. Other languages spoken include Kedayan, Tutong, Murut and Dusun.

Bulgaria

In the Bulgarian census, the question about the mother tongue and the ethnic group is an optional one. The results among the people that have answered both questions according to the latest census in 2011 are:

Language	People

China

1990 map of Chinese ethnolinguistic groups

There are abouts 292 living languages in China. The languages most commonly spoken belong to the Sinitic branch of the Sino-Tibetan language family, which contains Mandarin (spoken natively by 70% of the population), and other Chinese languages: Wu (including Shanghainese), Yue (including Cantonese and Taishanese), Min (including Hokkien and Teochew), Xiang, Gan, and Hakka. Languages of the Tibeto-Burman branch, including Tibetan, Qiang, Naxi and Yi, are spoken are spoken across the Tibetan and Yunnan–Guizhou Plateau. Other ethnic minority languages in southwest China include Zhuang, Thai, Dong and Sui of the Tai-Kadai family, Miao and Yao of the Hmong–Mien family, and Wa of the Austroasiatic family. Across northeastern and northwestern China, minority ethnic groups speak Altaic languages including Manchu, Mongolian and several Turkic languages: Uyghur, Kazakh, Kyrgyz, Salar and Western Yugur. Korean is spoken natively along the border with North Korea. Sarikoli, the language of Tajiks in western Xinjiang, is an Indo-European language. Taiwanese aborigines, including a small population on the mainland, speak Austronesian languages.

Standard Mandarin, a variety of Mandarin based on the Beijing dialect, is the official national language of China and is used as a lingua franca in the country between people of different linguistic backgrounds.

Chinese characters used as the written script for the Sinitic languages for thousands of years. They allow speakers of mutually unintelligible Chinese varieties to communicate with each other through writing. In 1956, the government introduced simplified characters, which have supplanted the older traditional characters in mainland China. Chinese characters are romanized in the Pinyin system. Tibetan uses an alphabet based on an Indic script. Uyghur is most commonly written in a Perseo-Arabic script. The Mongolian script used in China and the Manchu script are both derived from the Old Uyghur alphabet. Modern Zhuang uses the Latin alphabet.

Cyprus

Cyprus has two official languages, Greek and Turkish. Armenian and Cypriot Maronite Arabic are recognized as minority languages. Although without official status, English is widely spoken. English features on road signs, public notices, and in advertisements, etc. English was the sole official language during British colonial rule and lingua franca (until 1960) and continued to be used (de facto) in courts of law until 1989 and in legislature until 1996. A reported 80.4% of Greek Cypriots have command of the English language as second language (L2). Russian is widely spoken among the country's minorities, residents and citizens of post-Soviet countries, as well as Pontic Greeks. It is used and spoken by approximately 100,000 people, including Russians, Ukrainians, Belarusians, Armenians, Pontic Greeks, Georgians and Bulgarians. Russian, after English and Greek, is the third language used on many signs of shops and restaurants, particularly in Limassol and Paphos. In addition to these languages, 12% speak French and 5% speak German.

The everyday spoken language of Greek Cypriots is Cypriot Greek and that of Turkish Cypriots is Cypriot Turkish. These both differ from their respective standard register quite significantly.

Czech Republic

The first official censuses for the Czech lands (then part of Austria-Hungary) in the years 1869-1910 recorded each person's "language of communication" ("obcovací řeč"). This used to be criticised by linguistic minorities as representing the language of a person's surroundings rather than his or her own. The Czechoslovak censuses (1921, 1930, 1950, 1961, 1980) did not register respondents' language but "národnost" (ethnicity) which was to be assessed primarily, but not exclusively, on the basis of the person's "maternal tongue" ("mateřská řeč"). The 1970 census as well as modern censuses (1990, 2001, 2011) register both "ethnicity" and "maternal tongue" (which was, for example in the 2001 census, defined as "the language in which your mother or the persons having raised you spoke with you during your childhood"). The 2011 census form was the first to allow a person to claim two native languages. While certain options are habitually suggested in the form (in 2011: Czech, Slovak, Romani, Polish, German, sign language), the possibility "Other" can be chosen together with completing one's own specification. Unlike "ethnicity", this is an obligatory field in the form.

As the 2011 census introduced the possibility to state two native languages, the table below includes the number in both languages’ rows.

Further information: Languages of Finland

According to the Finnish constitution, the two national languages of Finland are Finnish and Swedish. About six per cent of the Finnish people speak Swedish as their mother tongue. The constitution also grants for the speakers of Sami, Romani and other languages the right to maintain and develop their language and culture. The right to use sign language is also set in the Finnish Language Act. In accordance with the Population Census Act, censuses are drawn every ten years, and the mother tongue of each resident is registered. However, key census data, including population by native language, are updated annually. According to the official statistics, speakers of 155 different languages have been registered. The censuses use the ISO 639-1 language classification.

France

Further information: Languages of France

France recognizes but one language, French, declared national language. Other indigenous languages have no official status, although their teaching is tolerated in some places under specific conditions, and there has never been any question about languages in a French national census.

However, the March 1999 census was associated with an INSEE survey "Study of family history" for 380 thousand people, including questions about language transmission.

Germany

The census 2011 and the West-German census 1987 did not inquire about language.

Greece

The official language of Greece is Greek, spoken by 99% of the population. In addition, a number of non-official, minority languages and some Greek dialects are spoken as well. The most common foreign languages learned by Greeks are English, German, French, Spanish and Italian.

Haiti

Main articles: Haitian French and Haitian Creole

The two official languages of Haiti are French and Haitian Creole. French is the principal written and administratively authorized language. It is spoken by all educated Haitians, is the medium of instruction in most schools, and is used in the business sector. It is also used in ceremonial events such as weddings, graduations and church masses. Haiti is one of two independent nations in the Americas (along with Canada) to designate French as an official language; the other French-speaking areas are all overseas départements, or collectivités, of France. Haitian Creole, which recently undergone a standardization, is spoken by virtually the entire population of Haiti. Haitian Creole is one of the French-based creole languages. Its vocabulary is 90% derived from French, but its grammar and influences are from some West African, Taino, Spanish, and Portuguese languages. Haitian Creole is related to the other French creoles, but most closely to Antillean Creole and Louisiana Creole.

Hong Kong

Officially English and Chinese are the two official language of Hong Kong. The definition of Chinese is somehow ambiguous as Chinese itself consists of a number of mutually unintelligible varieties. Cantonese is the major spoken language in Hong Kong and written in various form with Traditional Chinese characters. English is a variant of British English, though American English is also commonly used in Hong Kong.

From 19th century, censuses have investigated what languages the people of Hong Kong speak. Hakka, Hoklo, and Tanka have lost importance over time. Cantonese has come to be spoken by the vast majority, though there are increasingly more Mandarin-speaking people, particularly since the turn of the millennium.

Hungary

Starting from 1880 the Hungarian census system was based on native language (the language spoken at home in the early life of the person and at the time of the survey), vulgar language (the most frequently used language in the family), and other spoken languages.

Iceland

Iceland has been a very isolated and linguistically homogeneous island historically, but has nevertheless beheld several languages. Gaelic was native to many of the early Icelanders, the Icelandic or Norse language however prevailing, albeit absorbing Gaelic features. Later, northern trade routes brought German, English, Dutch, French and Basque. Some merchants and clergymen settled in Iceland throughout the centuries, leaving their mark on culture, but linguistically mainly trade, nautical or religious terms. Excluding these and Latin words, Icelandic has altered remarkably little since settlement, the island's residents living in seclusion.

Icelandic is not only the national language, but is now “the official language in Iceland” by virtue of Act No 61/2011, adopted by parliament in 2011. Icelandic Sign Language was also officially recognised by law in 2011 as a minority language with constitutional rights and the first language of the Icelandic deaf community. During the time of Danish rule, Danish was a minority language in Iceland, although it is nowadays only spoken by a small number of immigrants.

Studying English and Danish (or another Scandinavian language) is mandatory for students in compulsory schools and also part of many secondary-level study programmes, so knowledge of the two languages is widespread. Other foreign language frequently studied include German, Spanish and French.

Temporary visitors and residents often make up a large portion of the population, especially in the capital Reykjavík.

India

Main article: List of languages by number of native speakers in India

The population of India in 1991 exhibited 19.4% bilingualism and 7.2% trilingualism.

Indonesia

Indonesian is an official language but there are so many different languages native to Indonesia. According to Ethnologue, there are currently about 737 living languages, the most widely spoken being Javanese languages.

A number of Chinese varieties, most prominently Min Nan, are also spoken. The public use of Chinese, especially Chinese written characters, was officially discouraged between 1966 and 1998.

Iran

File:Moderniranianlanguagesmap.jpg

Geographic distribution of the modern Iranian languages: Persian (green), Pashto (purple) and Kurdish (turquoise), as well as smaller communities of other Iranian languages

The majority of the population speaks the Persian language, which is also the official language of the country, as well as other Iranian languages or dialects. Turkic languages and dialects, most importantly Azerbaijani language, are spoken in different areas in Iran. In southwestern and southern Iran, the Luri language and Lari language are spoken. In Kurdistan Province and nearby area's Kurdish is widely spoken. In Khuzestan, many distinct Persian dialects are spoken. Arabic is also spoken in Khuzestan. Notable minority languages in Iran include Armenian, Georgian, and Neo-Aramaic. Circassian was also once widely used by the large Circassian minority, but due to assimilation over the many years no sizable number of Circassians speak the language anymore.

Iraq

Arabic is the majority language while Kurdish is spoken by approximately 10–15% of the population and Turkmen, the Neo-Aramaic language of the Assyrians and others, by 5%. Other smaller minority languages includes Mandaic, Shabaki, Armenian, Circassian and Persian. Arabic, Kurdish, Persian, and South Azeri are written with versions of the Arabic script, the Neo-Aramaic languages in the Syriac script and Armenian is written in the Armenian script.

Previously to the invasion in 2003, Arabic was the sole official language. Since the new Constitution of Iraq was approved in June 2004, both Arabic and Kurdish are an official languages, while Assyrian Neo-Aramaic and Turkmen language (referred to as respectively "Syriac" and "Turkmen" in the constitution) are recognized as a regional languages. In addition, any region or province may declare other languages official if a majority of the population approves in a general referendum.

Based on the Iraqi constitution: "The Arabic language and the Kurdish language are the two official languages of Iraq. The right of Iraqis to educate their children in their mother tongue, such as Turkmen, Assyrian, and Armenian shall be guaranteed in government educational institutions in accordance with educational guidelines, or in any other language in private educational institutions".

Ireland

Questions relating to the ability to speak the Irish Language are included in the census. The figures obtained have been criticised as inflated by cognitive biases, such as response bias or wishful thinking. The 2006 census included an additional question on frequency of speaking Irish.

Italy

Italian censuses used to mainly observe, until recent times, the use of formal Italian language in its relationship with the use of other local languages (often considered as dialects), and they did not make comparisons with native languages other than Italian (in certain areas of Italy other languages are additionally official, such as German in Trentino-Alto Adige and other areas, Slovenian Slovenian in Friuli Venezia Giulia). Many reasons, indeed, still make it important to follow the evolution of the national official language, and among them are the late achievement of sufficient standards of literacy and of educational accomplishments, together with the particular and complex history of Italian languages/dialects and the wideness of their use in literature and in other forms of art (notably theatre and cinematography). Some of the languages spoken, different from Italian, which are in common use in Italy are, among the many, Sardinian, used in Sardinia, Sicilian used in Sicily, Friulian used in Friuli-Venezia Giulia, Venetian used mainly in Veneto.

With the Istat's report of 2012, this comparison has been added, while in the previous 2006 report foreign languages were observed only as additional idioms spoken, and not as eventual mother tongues.

According to the latest report, 53,1% of Italians aged 18 to 74 speak prevalently Italian at home, 56,4% speak it as their main language when interacting with friends, and 84,8% use it with outsider interlocutors. 5,8% is the percentage of other mother tongues speakers (but only 5,1% know Italian as their additional language). The knowledge of foreign languages is as follows:

• 43,7% English;
• 21,7% French;
• 4,8% German;
• 4,5% Spanish.

Ivory Coast

French, as an official language, is taught in schools and serves as a lingua franca in the country. Ethnic groups include Akan 42.1%, Voltaiques or Gur 17.6%, Northern Mandes 16.5%, Krous 11%, Southern Mandes 10%, other 2.8% (includes 30,000 Lebanese and 45,000 French; 2004). 77% of the population are considered Ivoirians. They represent several different peoples and language groups. An estimated 65 languages are spoken in the country. One of the most common is Dyula, which acts as a trade language as well as a language commonly spoken by the Muslim population.

Jamaica

The official language of Jamaica is English. Jamaicans primarily speak an English-African Creole language known as Jamaican Patois, which has become known widely through the spread of Reggae music. Jamaican Patois was formed from a base of mainly English words with elements of re-formed grammar, together with a little vocabulary from African languages and Native American words. Some archaic features are reminiscent of Irish English.

Japan

More than 99 percent of the population speaks Japanese as their first language. Japanese is an agglutinative language distinguished by a system of honorifics reflecting the hierarchical nature of Japanese society, with verb forms and particular vocabulary indicating the relative status of speaker and listener. Japanese writing uses kanji (Chinese characters) and two sets of kana (syllabaries based on simplified Chinese characters), as well as the Latin alphabet and Arabic numerals.

Besides Japanese, other languages like Ryukyuan languages (Amami, Kunigami, Okinawan, Miyako, Yaeyama, Yonaguni), also part of the Japonic language family, are spoken in the Ryukyu Islands chain. Few children learn these languages, but in recent years the local governments have sought to increase awareness of the traditional languages. The Okinawan Japanese dialect is also spoken in the region. The Ainu language, which has no proven relationship to Japanese or any other language, is moribund, with only a few elderly native speakers remaining in Hokkaido. Most public and private schools require students to take courses in both Japanese and English.

As of the last national census in 2002, of the republic's 2,022,547 people, 67% speak Macedonian as their mother tongue. The next most common mother tongue is Albanian with 25% of the population. Other minority languages include Turkish (3.6%), Romani (1.9%), and the Serbo-croatian languages (1.6%).

Malaysia

Further information: Languages of Malaysia

The national or official language is Malay which is the mother tongue of the majority Malay ethnic group. The main ethnic groups within Malaysia comprise the Malays, Chinese and Indians, with many other ethnic groups represented in smaller numbers, each with its own languages. The largest native languages spoken in East Malaysia are the Iban, Dusunic and the Kadazan languages. English is widely understood in service industries and is a compulsory subject in primary and secondary school. It is also the main language spoken in most private colleges and universities. Beside that, English may take precedence over Malay in certain official contexts as provided for by the National Language Act, especially in the states of Sabah and Sarawak, where it may be the official working language.

Malaysia contains speakers of 137 living languages, 41 of which are found in Peninsula Malaysia. The government provides schooling at the primary level in each of the three major languages, Malay, Chinese (Mandarin), and Tamil. Within these three there are a number of dialectal differences.

Mongolia

The official language of Mongolia is Mongolian, and is spoken by 95% of the population. A variety of dialects of Oirat and Buryat are spoken across the country, and there are also some speakers of Mongolic Khamnigan. In the west of the country, Kazakh and Tuvan, both Turkic languages, are also spoken. Mongolian Sign Language is the principal language of the deaf community.

Today, Mongolian is written using the Cyrillic alphabet, although in the past it was written using the Mongolian script. An official reintroduction of the old script was planned for 1994, but has not taken place as older generations encountered practical difficulties. The traditional alphabet is being slowly reintroduced through schools.

Russian is the most frequently spoken foreign language in Mongolia, followed by English, although English has been gradually replacing Russian as the second language. Korean has gained popularity as tens of thousands of Mongolians work in South Korea.

Interest in Chinese, as the language of the other neighbouring power, has been growing. A number of older educated Mongolian citizens speak some German, as they studied in the former East Germany, while a few speak other languages from the former Eastern Bloc. Many younger people are fluent in the Western European languages as they study or work in, among other places, Germany, France and Italy.

Nepal

Further information: Languages of Nepal

The 2011 National census lists 123 languages spoken as a mother tongue (first language) in Nepal. Most belong to the Indo-Aryan and Sino-Tibetan language families. An overview of Nepali languages is found in the work of Toba, Toba, and Rai.

The official language of Nepal is Nepali (नेपाली), formerly called Khaskura then Gorkhali. According to the 2011 national census, the percentage of people with Nepali as the mother tongue is 44.6%.

Norway

In the Norwegian census of 1970, in limited areas in Northern Norway, people were identified by ethnicity and language. Such information has not been included in any census since then. During the 19th Century, the Norwegian government collected ethnicity and language information.

References:

Ethnologue lists 175 individual languages in the Philippines, 171 of which are living languages, while 4 no longer have any known speakers. Most native languages are part of the Philippine branch of the Malayo-Polynesian languages, which is itself a branch of the Austronesian language family. The only non-Austronesian language indigenous to the Philippines is Chavacano, a Spanish-based creole. According to the 1987 Philippine Constitution, Filipino and English are the official languages. Filipino is a standardized version of Tagalog, spoken mainly in Metro Manila and other urban regions. Both Filipino and English are used in government, education, print, broadcast media, and business. The constitution mandates that Spanish and Arabic shall be promoted on a voluntary and optional basis.

Nineteen regional languages act as auxiliary official languages used as mediums of instruction: Aklanon, Bikol, Cebuano, Chavacano, Hiligaynon, Ibanag, Ilocano, Ivatan, Kapampangan, Kinaray-a, Maguindanao, Maranao, Pangasinan, Sambal, Surigaonon, Tagalog, Tausug, Waray, and Yakan. Other indigenous languages such as, Cuyonon, Ifugao, Itbayat, Kalinga, Kamayo, Kankanaey, Masbateño, Romblomanon, and several Visayan languages are prevalent in their respective provinces. The Chavacano language, a creole language born from Spanish (of the Mexican and Peruvian strain), is also spoken in Cavite and Zamboanga. Languages not indigenous to the islands are also taught in select schools. Standard Mandarin is used in Chinese schools catering to the Chinese Filipino community. Islamic schools in Mindanao teach Modern Standard Arabic in their curriculum. French, German, Japanese, Korean, Spanish are taught with the help of foreign linguistic institutions, respectively, Alliance Francaise, Goethe Institut, Japan Foundation, Korean Cultural Center or King Sejong Institute, and Instituto Cervantes. The Department of Education began teaching the Malay languages Indonesian and Malaysian in 2013.

Qatar

Arabic is the official language of Qatar, with Qatari Arabic the local dialect. Qatari Sign Language is the language of the deaf community. English is also widely spoken, and is considered to be a rising lingua franca, especially in commerce, to the extent that steps are being taken to try to preserve Arabic from English's encroachment. English is particularly useful for communication with Qatar's large expatriate community. In 2012, Qatar joined the international French-speaking organisation of La Francophonie as a new associate member, justifying its inscription by the consequent number of French speakers in the country (10% of the Qatari population would be francophone). Reflecting the multicultural make-up of the country, many other languages are also spoken, including Hindi, Malayalam, Urdu, Tamil, Nepali and Tagalog.

Singapore

Native languages (mother tongues) of Singaporeans
Language			Percent
Mandarin Chinese			50%
English			32%
Malay			12%
Tamil			3%

Singapore has four official languages. The four languages that are recognised by the Singapore Government are: English, Malay, Mandarin, and Tamil. They were chosen to correspond with the major ethnic groups present in Singapore at the time as well as for the following reasons: Mandarin had gained status since the introduction of Chinese-medium schools; Malay was deemed the "most obvious choice" for the Malay community; and Tamil for the largest Indian ethnic group in Singapore, in addition to being "the language with the longest history of education in Malaysia and Singapore". In 2009, more than 20 languages were identified as being spoken in Singapore, reflecting a rich linguistic diversity in the city. Singapore's historical roots as a trading settlement gave rise to an influx of foreign traders, and their languages were slowly embedded in Singapore's modern day linguistic repertoire.

Quadrilingual warning sign written in Singapore's four official languages; English, Chinese, Tamil and Malay.

Malay is the national language of the country, although English is mainly used. English serves as the link between the different ethnic groups and is the language of the educational system and the administration. The colloquial English used in everyday life is often referred to as Singlish.

The government of Singapore has been promoting the use of Mandarin, the official form of Chinese in Singapore as well as mainland China and Taiwan, with its Speak Mandarin Campaign among the Chinese population. The use of other varieties of Chinese, like Hokkien, Teochew, Cantonese, Hainanese and Hakka, has been declining over the last two decades, although they are still being used especially by the older generations of the Chinese population.

About 60% of Singapore's Indian population speaks Tamil as their native language. Other widely spoken Indian languages are Punjabi, Malayalam, Hindi and Telugu.

Around 5,000 Peranakans, the early Chinese population of the region, still use the Hokkien-influenced Malay dialect that called Baba Malay.

Spain

The languages of Spain (simplified)

Spanish official and spoken all over the country   Catalan/Valencian, co-official   Basque, co-official   Galician, co-official

Aranese (a dialect of Occitan), co-official   Asturian, recognized   Aragonese, recognized   Leonese, unofficial   Extremaduran, unofficial   Fala, unofficial

Spain is openly multilingual, and the constitution establishes that the nation will protect "all Spaniards and the peoples of Spain in the exercise of human rights, their cultures and traditions, languages and institutions.

Spanish (español)—officially recognized in the constitution as Castilian (castellano)—is the official language of the entire country, and it is the right and duty of every Spaniard to know the language. The constitution also establishes that "all other Spanish languages"—that is, all other languages of Spain—will also be official in their respective autonomous communities in accordance to their Statutes, their organic regional legislations, and that the "richness of the distinct linguistic modalities of Spain represents a patrimony which will be the object of special respect and protection."

The other official languages of Spain, co-official with Spanish are:

• Basque (euskara) in the Basque Country and Navarre;
• Catalan (català) in Catalonia, the Balearic Islands and in the Valencian Community, where its distinct modality of the language is officially known as Valencian (valencià); and
• Galician (galego) in Galicia

As a percentage of the general population, Basque is spoken by 2%, Catalan (or Valencian) by 17%, and Galician by 7% of all Spaniards.

In Catalonia, Aranese (aranés), a local variety of the Occitan language, has been declared co-official along with Catalan and Spanish since 2006. It is spoken only in the comarca of Val d'Aran by roughly 6,700 people. Other Romance minority languages, though not official, have special recognition, such as the Astur-Leonese group (Asturian, asturianu; also called "bable", in Asturias and Leonese, llionés, in Castile and León) and Aragonese (aragonés) in Aragon.

In the North African Spanish autonomous city of Melilla, Riff Berber is spoken by a significant part of the population. In the tourist areas of the Mediterranean coast and the islands, English and German are widely spoken by tourists, foreign residents, and tourism workers.

Sri Lanka

The Sinhala language is spoken by the Sinhalese people, who constitute approximately 74% of the national population and total about 13 million. It utilizes the Sinhala abugida script, which is derived from the ancient Brahmi script. The Rodiya language, a dialect of Sinhala, is spoken by the low-caste community of chamodi veddhas. The Veddah peoples, totaling barely 2500, speak a distinct language, possibly a creolized form of an earlier indigenous language. The Tamil language is spoken by Sri Lankan Tamils, as well as by Tamil migrants from the neighboring Indian state of Tamil Nadu and by most Sri Lankan Moors. Tamil speakers number around 4.7 million. There are more than 50,000 speakers of the Sri Lankan Creole Malay language, which is strongly influenced by the Malay language.

Suriname

Indian immigrants from British India

Dutch is the sole official language, and is the language of education, government, business, and the media. Over 60% of the population speak Dutch as a mother tongue, and most of the rest speak it as a second language. In 2004 Suriname became an associate member of the Dutch Language Union. It is the only Dutch-speaking country in South America as well as the only independent nation in the Americas where Dutch is spoken by a majority of the population, and one of the two non-Romance-speaking countries on the continent, the other being English-speaking Guyana.

In Paramaribo, Dutch is the main home language in two-thirds of households. The recognition of "Surinaams-Nederlands" ("Surinamese Dutch") as a national dialect equal to "Nederlands-Nederlands" ("Dutch Dutch") and "Vlaams-Nederlands" ("Flemish Dutch") was expressed in 2009 by the publication of the Woordenboek Surinaams Nederlands (Surinamese–Dutch Dictionary). Only in the interior of Suriname is Dutch seldom spoken.

Sranan, a local creole language originally spoken by the creole population group, is the most widely used language in the streets and is often used interchangeably with Dutch depending on the formality of the setting.

Surinamese Hindi or Sarnami, a dialect of Bhojpuri, is the third-most used language, spoken by the descendants of South Asian contract workers from then British India. Javanese is used by the descendants of Javanese contract workers. The Maroon languages, somewhat intelligible with Sranan Tongo, include Saramaka, Paramakan, Ndyuka (also called Aukan), Kwinti and Matawai. Amerindian languages, spoken by Amerindians, include Carib and Arawak. Hakka and Cantonese are spoken by the descendants of the Chinese contract workers. Mandarin is spoken by some few recent Chinese immigrants. English, Spanish and Portuguese are also used. Spanish and Portuguese are spoken by Latin American residents and their descendants and sometimes also taught in schools.

The public discourse about Suriname's languages is a part of an ongoing debate about the country's national identity. The use of the popular Sranan became associated with nationalist politics after its public use by former dictator Dési Bouterse in the 1980s, and groups descended from escaped slaves might resent it. Some propose to change the national language to English, so as to improve links to the Caribbean and North America, or to Spanish, as a nod to Suriname's location in South America, although it has no Spanish-speaking neighbours.

Switzerland

Languages of Switzerland, red German, blue French, green Italian, yellow Romansh

See also: Languages of Switzerland

From 1850 until 2000, Switzerland had a census every 10 years. Beginning in 2010, they switched to a yearly system which used a combination of municipal citizen records and a limited number of surveys. Data on the main language spoken by citizens and non-citizen residents has been collected since at least 1970. Of the four official languages, German is the most commonly spoken, with 64.94% of the total population speaking it in 1970 and 63.67% in 2000. French was spoken by 18.09% in 1970 and 20.38% in 2000, while Italian was 11.86% in 1970 and 6.46% in 2000. The fourth national language, Romansh was spoken by just 0.8% in 1970 and 0.48% in 2000. In the 2000 census, English (1.01%), Spanish (1.06%), Portuguese (1.23%), Serbian and Croatian (1.42%) and Albanian (1.30%) were all spoken by significantly more residents than Romansh.

Selected languages from the 1970 to 2000 census are given in the following table:

Census	German	French	Italian	Romansh	English	Dutch	Spanish	Slavic (Except Czech and Slovak)	Czech and Slovak

Syria

Arabic is an official language of Syria. Several modern Arabic dialects are used in everyday life, most notably Levantine in the west and Mesopotamian in the northeast. Kurdish (in its Kurmanji form) is widely spoken in the Kurdish regions of Syria. Armenian and Turkish (South Azeri dialect) are spoken among the Armenian and Turkmen minorities.

Aramaic was the lingua franca of the region before the advent of Arabic, and it is still spoken among Assyrians, and Classical Syriac still used as the liturgical language of various Syriac Christian denominations. Most remarkably, Western Neo-Aramaic is still spoken in the village of Ma'loula as well as two neighboring villages, 35 miles (56 km) northeast of Damascus. Many educated Syrians also speak English and French languages.

United States

Language use and English-speaking ability are currently collected in the American Community Survey (an ongoing statistical survey by the U.S. Census Bureau, sent to approximately 250,000 addresses monthly, or 3 million per year). In the past, various questions on language use were asked in the censuses from 1890 to 1970. The three questions below were asked in the census in 1980, 1990, and 2000 and are the same questions asked in the American Community Survey.

a. Does this person speak a language other than English at home?

• Yes
• No

b. What is this language? (For example: Korean, Italian, Spanish, Vietnamese)

c. How well does this person speak English?

• Very well
• Well
• Not well
• Not at all

The coding operations used by the Census Bureau puts the reported answers from the question "What is this language?" into 382 language categories of single languages or language families. These categories represent the most commonly spoken languages other than English at home in the U.S. Due to small sample counts, data tabulations are not generally available for all 382 detailed languages. Instead, the Census Bureau collapses languages into smaller sets. These sets of languages were originally developed following the 1970 Census and are grouped linguistically and geographically. The simplest collapse recodes the 382 language codes into four major language groups: Spanish; Other Indo-European languages; Asian and Pacific Island languages; and All Other languages. A more detailed collapsing puts the 382 codes into 39 languages and language groups.

Uzbekistan

People in Uzbekistan (when it was still a part of the Russian Empire) were enumerated by native tongue in the 1897 Russian Empire Census. The Soviet Union (to which Uzbekistan also belonged) enumerated people by ethnicity for its entire existence. Uzbekistan has not conducted any censuses at all since 1989.

Vatican City

Vatican City enumerated people by ethnicity in 1948.

Vietnam

People in Vietnam were enumerated by ethnicity in 1979, 1989, 1999, 2009 and 2014.

Yemen

Ethnoreligious composition of Yemen in 2002.

Yemen enumerated its population by ethnicity in 1994. The British Colony of Aden (which is within Yemen's current borders) enumerated its population by ethnicity in 1946 and 1955.
