Approximately 430 million people speak English as their first language.[year needed] More than half of these (255 million) live in the United States, followed by some 60 million in the United Kingdom (Great Britain being the language's historical homeland).
Estimates that include second language speakers vary greatly, from roughly 1 to 1.5 billion. When combining native and non-native speakers, English may or may not be the most widely spoken language worldwide, competing only with the Chinese languages (depending both on the definition of "Chinese language" and on what counts as second language competence).
Besides the major varieties of English, such as British English, American English, Australian English and their sub-varieties, countries such as the Philippines, Jamaica and Nigeria also have millions of native speakers of dialect continua ranging from an English-based creole to a more standard version of English.
Majority English-speaking countries
There are six countries with a majority of native speakers of English: the United Kingdom (97%, 64 million), the Republic of Ireland (94%, 4.3 million), Australia (87%, 17 million), New Zealand (82%, 3.7 million), the United States (79%, 255 million), and Canada (59%, 19 million). These six countries are also summarized under the term Anglosphere.
Besides these, Jamaica and Trinidad and Tobago have majorities natively speaking an English creole, or a patois in a "post-creole continuum". Other substantial communities of native speakers are found in South Africa (4.9 million, 30%), Nigeria (4 million, 5%) and Singapore (1 million, 17%).
English is also the primary language in the island states and territories of Anguilla, Antigua and Barbuda, the Bahamas, Barbados, Belize, Bermuda, the British Indian Ocean Territory, the British Virgin Islands, the Cayman Islands, Dominica, the Falkland Islands, Gibraltar, Grenada, Guam, Guernsey, Guyana, the Isle of Man, Jersey, Montserrat, Nauru, Pitcairn Islands, Saint Helena, Ascension and Tristan da Cunha, Saint Kitts and Nevis, Saint Vincent and the Grenadines, South Georgia and the South Sandwich Islands, the Turks and Caicos Islands.
Countries where English is an official language
In some countries where English is not the most spoken language, it is an official language; these countries include Botswana, Cameroon, the Federated States of Micronesia, Fiji, Gambia, Ghana, Hong Kong, India, Kenya, Kiribati, Lesotho, Liberia, Malta, the Marshall Islands, Mauritius, Namibia, Nigeria, Pakistan, Palau, Papua New Guinea, the Philippines (Philippine English), Rwanda, Saint Lucia, Samoa, Seychelles, Sierra Leone, the Solomon Islands, Sri Lanka, Sudan, South Africa, South Sudan, Swaziland, Tanzania, Uganda, Zambia, and Zimbabwe. Also there are countries where in a part of the territory English became a co-official language, e.g. Colombia's San Andrés y Providencia and Nicaragua's Mosquito Coast. This was a result of the influence of British colonization in the area.
English is one of the 11 official languages that are given equal status in South Africa (South African English). It is also the official language in current dependent territories of Australia (Norfolk Island, Christmas Island and Cocos Island) and of the United States (American Samoa, Guam, Northern Mariana Islands, Puerto Rico (in Puerto Rico, English is co-official with Spanish), and the US Virgin Islands), and the former British colony of Hong Kong. (See List of countries where English is an official language for more details.)
Although the United States federal government has no official languages, English has been given official status by 30 of the 50 state governments. Although falling short of official status, English is also an important language in several former colonies and protectorates of the United Kingdom, such as Bahrain, Bangladesh, Brunei, Cyprus, Malaysia, and the United Arab Emirates.
English as a global language
Because English is so widely spoken, it has often been referred to as a "world language", the lingua franca of the modern era, and while it is not an official language in most countries, it is currently the language most often taught as a foreign language. It is, by international treaty, the official language for aeronautical and maritime communications. English is one of the official languages of the United Nations and many other international organizations, including the International Olympic Committee.
English is studied most often in the European Union, and the perception of the usefulness of foreign languages among Europeans is 67% in favor of English ahead of 17% for German and 16% for French (as of 2012). Among some of the non-English-speaking EU countries, the following percentages of the adult population claimed to be able to converse in English in 2012: 90% in the Netherlands, 89% in Malta, 86% in Sweden and Denmark, 73% in Cyprus and Austria, 70% in Finland, and over 50% in Greece, Luxembourg, Slovenia and Germany. In 2012, excluding native speakers, 38% of Europeans consider that they can speak English, but only 3% of Japanese people.
Books, magazines, and newspapers written in English are available in many countries around the world, and English is the most commonly used language in the sciences with Science Citation Index reporting as early as 1997 that 95% of its articles were written in English, even though only half of them came from authors in English-speaking countries.
This increasing use of the English language globally has had a large impact on many other languages, leading to language shift and even language death, and to claims of linguistic imperialism. English itself has become more open to language shift as multiple regional varieties feed back into the language as a whole.
