People who live in India are called Indians, and they have citizenship and nationality in the Republic of India. India is the world's second-most populated country, with 17.50 percent of the total population, according to the results of the national census that was conducted in India in 2011. The population of India was estimated to be more than 1.2 billion people at the time. In India, the word "Indian" refers to nationality, rather than a specific ethnicity or language; the Indian nationality comprises of dozens of regional ethnolinguistic groupings, reflecting the population's rich and complicated past. The Indian diaspora is prevalent all over the globe, particularly in various regions of Asia as well as in North America, Europe, the Caribbean, Oceania, and Africa. It is a considerable population that can be found in all of these locations. The term "Indian" refers to citizens of the Republic of India in the present day; however, prior to the partition of India in 1947, the term "Indian" referred to all people residing in the entirety of British India, which included what is now the countries of Pakistan and Bangladesh. Indians are citizens of the Republic of India in the present day.
The terms "Asian Indian" and "East Indian" are sometimes used in Canada, the Caribbean, and the United States. This is done to avoid any confusion with the "First Nations" of Canada, the indigenous peoples of the Caribbean, and the Native Americans of the United States, all of whom have been commonly referred to as "Indian" since the time of the European colonial era.
