British Indians are citizens of the United Kingdom (UK) whose ancestral roots are from India. Currently, the British Indian population exceeds 1.8 million people in the UK, making them the single largest visible ethnic minority population in the country. They make up the largest subgroup of British Asians and are one of the largest Indian communities in the Indian diaspora, mainly due to the Indian–British relations. The British Indian community is the sixth largest in the Indian diaspora, behind the Indian communities in the United States, Saudi Arabia, the United Arab Emirates, Malaysia and Nepal. The majority of British Indians are of Punjabi and Gujarati origin with various other smaller communities from different parts of India including Kerala, West Bengal, Bihar and Uttar Pradesh.

British Asians are British people 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.
