British Asians (also referred to as Asian Britons) are British citizens of Asian descent. They constitute a significant and growing minority of the people living in the United Kingdom, with 6.9% of the population identifying as Asian/Asian British in the 2011 United Kingdom census. This represented a national demographic increase from a 4.4% share of UK population in 2001.
Represented predominantly by South Asian ethnic groups, census data regarding birthplace and ethnicity demonstrate around a million Asian British people derive their ancestry between East Asia, Southeast Asia, Central Asia, and West Asia. Since the 2001 census, British people of general Asian descent have been included in the "Asian/Asian British" grouping ("Asian, Asian Scottish or Asian British" grouping in Scotland) of the UK census questionnaires. Categories for British Indians, British Pakistanis, British Bangladeshis, British Chinese, and other Asians have existed under an Asian British heading since the 2011 census. In British English usage, especially in less formal contexts, the term "Asian" usually refers to people who trace their ancestry to the Indian subcontinent (South Asia), contrary to other Anglosphere countries such as Australia and the United States, where the term "Asian" usually refers to people who trace their ancestry to the Far East (East Asia or Southeast Asia).
There is a long history of migration to the United Kingdom (and its predecessor states) from across Asia. British colonies and protectorates throughout Asia brought lascar sailors and militiamen to port cities in Britain. Immigration of small numbers of South Asians to England began with the arrival of the East India Company to the Indian subcontinent, and the decline of the Mughal Empire, at the end of the 16th century. Between the 17th and mid-19th century, increasingly diverse lascar crews heading for Britain imported East Asians, such as Japanese and Chinese seamen, Southeast Asians, such as Malays, South Asians such as the Indians (including the people from Pakistan), Bengalis and Ceylonese and post-Suez Canal; West Asians, such as Armenians and Yemenis, who settled throughout the United Kingdom.
