Over 2 billion people speak English, making English the largest language by number of speakers, the third largest language by number of native speakers. With 300 million native speakers, the United States of America is the largest English-speaking country. As pictured in the pie graph below, most native speakers of English are Americans. Additionally, there are 60 million native speakers in the United Kingdom, 29 million in Canada, 25.1 million in Australia, 4.7 million in the Republic of Ireland, and 4.9 million in New Zealand. In the European Union, English is one of 24 official languages and is widely used by institutions, and by a majority of the population as the native language in the United Kingdom and Ireland and as a second language in other member states. Estimates that include second language speakers vary greatly, from 470 million to more than 2 billion. David Crystal calculates that, as of 2003, non-native speakers outnumbered native speakers by a ratio of 3 to 1. When combining native and non-native speakers, English is the most widely spoken language worldwide.
Indian English refers to the regional variety of the English language spoken in the Republic of India, and Indian diaspora elsewhere in the world. The Constitution of India has mandated Hindi in the Devanagari script to be the official language of the Indian union; English is an additional official language for government work along with Hindi. English is also the sole official language of the Judiciary of India, unless a state Governor or legislature has mandated the use of a second regional official language, or Presidential approval has been given for the use of regional languages in courts.
