Cornish people or the Cornish are an ethnic group native to, or associated with Cornwall and a recognised national minority in the United Kingdom, which can trace its roots to the ancient Britons who inhabited Great Britain from somewhere between the 11th and 7th centuries BC and inhabited Britain at the time of the Roman conquest. Many in Cornwall today continue to assert a distinct identity separate from or in addition to English or British identities. Cornish identity has also been adopted by some migrants into Cornwall, as well as by emigrant and descendant communities from Cornwall, the latter sometimes referred to as the Cornish diaspora. Although not included as a tick-box option in the UK census, the numbers of those writing in a Cornish ethnic and national identity are officially recognised and recorded.
