Bulgaria

Bulgarian governors organized a national census soon after the liberation of the Bulgarian lands. In 1881 a census took place in the Principality, while in 1884 a census was organized in Eastern Rumelia. The first census covering the unified state took place in 1887.

Since these first accounts, Bulgarian authorities had organized several population censuses: 1892, 1900, 1905, 1910, 1920, 1926, 1934, 1946, 1956, 1965, 1975, 1985, 1992, 2001, and 2011.

The data provided in the Bulgarian censuses from 1888 until World War II is regarded as highly reliable according to the standards of the time. The Bulgarian leading statisticians of the period were generally educated in Western universities and participated vividly in the international cooperation, therefore insisted and succeeded in introducing the best practices of the time. The quality of the data provided of later censuses is a matter of debate. The religion question in the 2001 census didn't allow the unaffiliated Bulgarians to be counted as such.

Canada

Main article: Census in Canada

The Canadian census is run by Statistics Canada. The 1666 census of New France was conducted by French intendant Jean Talon, when he took a census to ascertain the number of people living in New France. The method and data was later used when Canada was founded 201 years later. The individual provinces (sometimes in conjunction with each other) conducted censuses in the 19th century and before. In 1871, Canada's first formal census was conducted, which counted the population of Nova Scotia, Ontario, New Brunswick, and Quebec.

Censuses in Canada are conducted in five-year intervals. The last census was conducted in 2011. Censuses taken in mid-decade (1976, 1986, 1996, etc.) are referred to as quinquennial censuses. Others are referred to as decennial censuses. The first quinquennial census was conducted in 1956.

For the 2006 Census of Canada, respondents were able, for the first time, to choose to complete their census questionnaire online. Other options for answering the questionnaire include postal mail (using a pre-paid envelope) and telephone (using an 800 number).

At a sub-national level, two provinces (Alberta and Saskatchewan) and two territories (Nunavut and Yukon) have legislation that allows local governments to conduct their own municipal censuses.

Chile

National population censuses are carried out in Chile every ten years by the National Statistics Institute (INE). The last one took place in 2012, but its results were dismissed by the INE due to a high omission rate and other problems. A new abbreviated census is planned for 2017, with a full census to be carried out in 2022. The last official census results are from 2002.

China

China's first censuses were irregular: the Republic of China held censuses in 1913 and 1944. Under Mao Zedong, the People's Republic of China held its first in 1952, but the second in 1963 was secret and unacknowledged until the early 1980s.

The 1982 Chinese Census was much more thorough and well-conducted than the first two, and similar censuses have been conducted decennially in 1990, 2000, and 2010. These are the world's biggest censuses and over 6 million enumerators were engaged in the 2000 and 2010 censuses.

Between the national censuses, 1% National Population Sample Surveys were taken in 1987, 1995, and 2005; 0.1% National Population Sample Surveys have been taken annually since 2000. National agricultural, economic, and industrial censuses are also taken on a regular basis. The first economic census was taken in 2004 and the second 2008.

Cyprus

The British colonisers carried out seven censuses in Cyprus in total: six at ten-year intervals between 1881 and 1931, and the last in 1946. Following the establishment of the modern state, there have been seven more censuses: in 1960 (the year of establishment), 1973, 1976, 1982, 1992, 2001 and 2011. The Statistical Service of the Cypriot government counts from the first British census, i.e. the latest census, in 2011, is referred to as the 14th census. In Northern Cyprus there have been three censuses: in 1996, 2006 and 2011. All three have been a matter of controversy, both in the north and the south, and abroad.

Czech Republic

The census in the Czech Republic is carried out every 10 years by the Czech Statistical Office. The last census was taken in 2011. Earlier censuses were taken in 1869, 1880, 1890, 1900, 1910, 1921, 1930, 1950, 1961, 1970, 1980, 1991 and 2001.

The results of the last census are also available via the interactive model based software.

Denmark

Main article: Census in Denmark

The first Danish census was in 1700–1701, and contained statistical information about adult men. Only about half of it still exists. A census of school children was taken during the 1730s.

Following these early undertakings, the first census to attempt completely covering all citizens (including women and children who had previously been listed only as numbers) of Denmark-Norway was taken in 1769. At that point there were 797,584 citizens in the kingdom. Georg Christian Oeder took a statistical census in 1771 which covered Copenhagen, Sjælland, Møn, and Bornholm.

After that, censuses followed somewhat regularly in 1787, 1801, and 1834, and between 1840 and 1860, the censuses were taken every five years, and then every ten years until 1890. Special censuses for Copenhagen were taken in 1885 and 1895.

In the 20th century, censuses were taken every five years from 1901 to 1921, and then every ten years from 1930. The last traditional census was taken in 1970.

A limited population census based on registers was taken in 1976. From 1981 and each year onwards information that corresponds to a population and housing census is retrieved from registers. Denmark was the first country in the world to conduct these censuses from administrative registers. The most important registers are the Population Register (Det Centrale Personregister), the Building and Dwelling Register and the Enterprise Register. The central statistical office, Statistics Denmark is responsible for compiling these data. This information is available online in the Statbank Denmark.

It is possible to search a portion of the Danish censuses online at the Dansk Demografisk Database, and also view scanned versions at Arkivalier Online.

Egypt

Main article: Census in Egypt

The Statistical Department of the Ministry of Finance conducted the first census in 1882, which considered as a preparatory step; the first true population census was conducted in 1897. Thereafter, censuses were conducted at ten-year intervals in 1907, 1917, 1927 and so on. The last one being in 2006.

Estonia

Population censuses have been carried out in 1881, 1897, 1922, 1934, 1959, 1970, 1979, 1989, 2000 and 2011

The censuses of 1881 and 1897 were carried out during the reign of the Russian Empire, when Estonia was divided between the Governorate of Estonia and the Governorate of Livonia. The latter also included territories of modern day Latvia, however its Estonian-populated counties of Võru, Tartu, Viljandi, Pärnu and Saaremaa roughly corresponded to the later borders of the Republic of Estonia. Only later Estonian territories of Valga, Narva, Jaanilinn and Petseri County remained outside these figures.

The 1922 and 1934 censuses were carried out by the independent Republic of Estonia. The 1959, 1979 and 1989 censuses were carried out by the Estonian SSR of the Soviet Union and excluded Jaanilinn and Petseri County, which were annexed by the Russian SFSR in 1945. The 2000 and 2011 censuses were again carried out by the independent Republic of Estonia and also excluded the territories annexed by Russia in 1945. The current responsible institution is the Statistics Estonia.

Ethiopia

Three censuses have been taken in Ethiopia: 1984, 1994 and in 2007. The responsible institution is the Central Statistical Agency.

Most of the census in 2007 was taken in August, while the Somali Region and the Afar Region were not covered. The northern Afar region is a remote, hot and arid area. The eastern Somali region (Ogaden) hosts a large nomadic Somali population and is a conflict area where Ethiopian regular forces are fighting against Ogaden National Liberation Front (ONLF).

Finland

Germany

Main article: Census in Germany

The first systematic population on the European continent was taken in 1719 in Prussia (roughly corresponding to today's northern Germany and western Poland).

The first large-scale census in the German Empire took place in 1895. Attempts at introducing a census in West Germany sparked strong popular resentment in the 1980s since many quite personal questions were asked. Some campaigned for a boycott. In the end the Constitutional Court stopped the census in 1980 and 1983. The last census was in 1987. Germany has since used population samples in combination with statistical methods, in place of a full census.

Greece

Census takes place every 10 years and is carried out by the National Statistical Service of Greece. The 2011 census ended on 24 May.

Guatemala

Modern population censuses have been taken in Guatemala in 1930, 1950, 1964, 1973, 1981, 1994 and in 2002. Controversial cenuses include those in 1950 and 1964 (misclassification of the Maya population) and 1994 (generally questioned). About 14,000,000 people live in Guatemala as of July 2009.

Hong Kong

Hungary

Official decennial censuses have been taken in Hungary since 1870; the latest one – in line with the recommendations of the United Nations and the Statistical Office of the European Union – was carried out in 2001. 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

The first Icelandic census took place in 1703, following upon the first Danish census of 1700–1701. Further censuses were carried out in 1801, 1845 and 1865. The 1703 exercise was the first census ever to cover all inhabitants of an entire country, mentioning the name, age, and social position of each individual. All of the information still exists, although some of the original documents have been lost.

The need for censuses was eliminated through the setting up, in 1952, of the National Registry (Þjóðskrá), which later merged with other entities to form Registers Iceland. All those born in Iceland, and all new residents, are automatically registered. Individuals are identified in the registry by means of a national identification number (the so-called kennitala), a number composed of the date of birth in the format ddmmyy and four additional digits, the third of which is a control digit, and the last of which indicates the century in which the person was born (9 for the 1900s and 0 for the 2000s).

The National Registry doubles as an electoral register. Likewise, all bank accounts are linked to the national identification of the owner (companies and institutions all have their own identification numbers).

India

Main article: Census of India

The decennial census of India is the primary source of information about the demographic characteristics of the population of India. The 2011 census is one of the largest censuses in the history of mankind.

The first census in India in modern times was conducted in 1872. First regular census was started in 1881 by Lord Ripon. Since then, a population census has been carried out every 10 years. The latest census commenced on May 1, 2010. It will create a National Population Register with photographs and fingerprints of every resident. All usual residents of India will also be provided with their Unique ID numbers and National Identity Cards. The census is carried out by the office of the Registrar General and Census Commissioner of India, Delhi, an office in the Ministry of Home Affairs, Government of India, under the 1948 Census of India Act. The act gives Central Government many powers like to notify a date for Census, power to ask for the services of any citizen for census work. The law makes it compulsory for every citizen to answer the census questions truthfully. The Act provides penalties for giving false answers or not giving answers at all to the census questionnaire. One of the most important provisions of law is the guarantee for the maintenance of secrecy of the information collected at the census of each individual. The census records are not open to inspection and also not admissible in evidence.

The census is conducted in two phases: first, house listing and house numbering phase and second, the actual population enumeration phase. The census is carried out by the canvassing method. In this method, each household is visited and the information is collected by specially trained enumerator. They collect data related to households e.g. number of members, water & electricity supply, ownership of land, vehicles, computers and other assets and services. In the second phase, total population is counted and statistics related to individuals are collected.

Indonesia

The first population census was done during the colonial era, 1930. Before that, a non-overall census was already conducted in 1920. After that census was done irregularly. The first census after independence was 1961, followed by 1971. Since 1980 it is conducted regularly every 10 years. In between, there is also economical census (every 10 years, five years after population census) and agricultural census (three years after population census). The last census was held on May 2010.

In Tokyo, people can choose to answer the census questions by filling out the paper form, or they can choose to answer census questions online. Unique ID and password are provided with the census form. The online census form is only available for residents of Tokyo. This is because a high concentration of people in Tokyo are living in apartment buildings or gated communities, which restricts the access of census workers.

Jordan

The first population census after the independence in 1946 was taken in 1952. It did only count the number of people in the households and could therefore be considered only to be a housing census. The first real complete census was taken in 1961. The following censuses have been taken in 1979, 1994 and 2004.

The first census in the Netherlands was conducted in 1795, and the last in 1971. A law was produced on April 22, 1879, ordering a census to be conducted every ten years.

The census that was planned for 1981 was postponed and later cancelled. A call for privacy was responsible for the cancellation of any further census since 1991. Censuses are being conducted by the Centraal Bureau voor de Statistiek since 1899. The censuses today are mostly (population, fiscal) register based, combined with surveying.

New Zealand

The census in New Zealand is carried out by Statistics New Zealand (Tatauranga Aotearoa), usually every five years. For the 2006 and 2013 Census of New Zealand, respondents could choose to complete their census questionnaire online. See New Zealand Census of Population and Dwellings. The Census scheduled for March 8, 2011 was cancelled due to the February 2011 Christchurch earthquake. A census was instead held on March 5, 2013.

Nigeria

Population censuses have been taken in Nigeria during colonial time in 1866, 1871, 1896, 1901, 1911, 1921 and 1952. The censuses covered only the southern part of the country except for the 1952 census which was country wide, and the censuses before 1921 were based on administrative estimates rather than on an actual enumeration.

Censuses during the independence were taken 1962, 1963, 1973, 1991 and 2006. The results of the 1962 census were considered inaccurate enough that a new census was ordered on February 19, 1963. The results from 1973 and 2006 were highly disputed, but no recounts were taken. The preliminary results for 2006 indicates a population of 140 million people. 700,000 enumerators were engaged in this operation.

Norway's first nominative, complete census was taken in 1801, when Norway still was ruled by the Oldenburg dynasty of Denmark-Norway. The scope of the census followed the de jure principle, so military persons should be included as well as foreigners if they were residents. The 1801, 1865, 1900 and 1910 censuses are transcribed and made searchable on the internet. The census records are made publicly available when 100 years have passed. Since 1900, a census has been conducted every ten years. (However, the 1940 census was postponed to 1946, and the census after 1990 came in 2001.) Since 2001 the population census has been combined with the housing statistics. The 2001 questionnaire only asked about households and who was living in them, while no questionnaires will be mailed out for the 2011 census, since the administrative data on households is sufficient.

Switzerland

Main article: Census in Switzerland

In Switzerland, the Federal Population Census (German: Eidgenössische Volkszählung, French: Recensement fédéral de la population, Italian: Censimento federale della popolazione, Template:Lang-rm) has been carried out every 10 years starting in 1850. The census was initiated by Federal Councillor Stefano Franscini, who evaluated the data of the first census all by himself after Parliament failed to provide the necessary funds. The census is now being conducted by the Swiss Federal Statistical Office.

Data collected include population data (citizenship, place of residence, place of birth, position in household, number of children, religion, languages, education, profession, place of work, etc.), household data (number of individuals living in the household, etc.), accommodation data (surface area, amount of rent paid, etc.) and building data (geocoordinates, time of construction, number of floors, etc.). Participation is compulsory and reached 99.87% of the population in 2000.

Since 2010, the population census has been carried out and analysed annually in a new format by the Federal Statistical Office (FSO). In order to ease the burden on the population, the information is primarily drawn from population registers and supplemented by sample surveys. Only a small proportion of the population (about 5%) is surveyed in writing or by telephone. The first reference day for the new census was December 31, 2010.

Now, the census takes place every 10 years. The last census was in 2000. It can be noted that the census enumeration takes place on one single day in Turkey (in other countries it takes 1–2 weeks). This required some 900,000 enumerators in 2000. The 15th census based on improved geographical information systems is planned for 2010.

A census was taken in the Ottoman Empire 1831–38 by Sultan Mahmud II (1808–1839) as a part of the reform movement Tanzimat. Christian and Jewish men were counted but the female population was excluded.

Uganda

The first censuses in Uganda were taken in 1911, 1921 and 1931. It was done in a rather primitive way. The enumeration unit was 'huts' and not individuals. More scientific censuses were taken 1948 and 1959 where the enumeration unit was persons. The census was however divided into two separate enumerations, one for Africans, and one for the non-African population. The censuses during independence 1969, 1980, 1991 were taken jointly for all races. The censuses 1980 and 1991 included housing information and in addition a larger questionnaire for a sample of the population. However, the questionnaires for the 1980 were lost and only provisional figures are available from this census.

The census in 2002 involved some 50,000 enumerators and supervisors. It covered several topics including: population and housing; agriculture; and Micro- and small Enterprises administered at individual/household level. The Preliminary Results were published two weeks after the enumeration. The Final Results were released in March 2005, while the analytical findings and the district level results were scheduled to be released in the second quarter of 2006.

The next census is planned for August 2014.

United Kingdom

Main article: Census in the United Kingdom

In the seventh century, Dál Riata was the first territory in what is now the UK to conduct a census. The Domesday Book of 1086 in England contained listings of households but its coverage was not complete and its intent was not the same as modern censuses.

Following the influence of Malthus and concerns stemming from his An Essay on the Principle of Population the UK census as we know it today started in 1801. The census has been conducted every ten years since 1801 and most recently in 2011.

The first four censuses (1801–1831) were mainly headcounts and contained little personal information. The 1841 Census, conducted by the General Register Office, was the first to record the names of everyone in a household or institution. From 1851 onwards the census shows the stated age and relationship to the head of household for each individual. Because of World War II, there was no census in 1941. The actual census dates were 6 June 1841, 30 March 1851, 7 April 1861, 2 April 1871, 3 April 1881, 5 April 1891, 31 March 1901, 27 March 1911.

The census of England & Wales is undertaken for the government by the Office for National Statistics (ONS). The General Register Office for Scotland (GROS) conducts its own census, while the census in Northern Ireland is carried out by the Northern Ireland Statistics and Research Agency (NISRA). Public access to the census returns is restricted under the terms of the 100-year rule. The most recent returns made available to researchers are those of the 1911 Census.

The most recent census, the United Kingdom Census 2011 took place on March 27, 2011. The next census will take place in 2021. The Office for National Statistics is looking into supplementing the census data with administrative data already collected by government departments and agencies, to lessen the burden on the population. They are also planning to conduct the 2021 Census online.

United States

See also: 2010 United States Census

The United States Constitution and federal law mandate that a census be taken every ten years in order to apportion the number of members of the United States House of Representatives among the several states. Census statistics are also used in order to apportion federal funding for many social and economic programs.

The first U.S. Census was conducted in 1790 by Federal marshals. During the 19th century and through the 1940 census, enumeration was accomplished through political districts. Each ward was responsible for producing a census.

From 1950 onward, census forms were mailed to every address on record with the United States Post Office, including the Armed Services Postal System, in an effort to enhance completeness of the data collected. Beginning in 1970, it was made illegal to fail to return a completed census form. Computer technology was also introduced.

The 2010 census counted over 308 million people.

By law (92 Stat. 915, Public Law 95-416, enacted on October 5, 1978), individual census records are sealed for 72 years. The individual census data most recently released to the public was the 1940 census, released on April 2, 2012. Aggregate census data are released when available.

In addition to the decennial federal census, local censuses have also been conducted, for example, in Massachusetts, which conducted a statewide census every five years until 1985. Some states conducted limited censuses for various purposes, and these are typically located in state archives.
