Indo-Guyanese or Indian-Guyanese, are people of Indian origin who are Guyanese nationals tracing their ancestry to India and the wider subcontinent. They are the descendants of indentured servants and settlers who migrated from India beginning in 1838 during the time of the British Raj. Indo-Guyanese are the largest ethnic group in Guyana identified by the official census, about 40% of the population in 2012. There is also a large Indo-Guyanese diaspora in countries such as the United States, Canada and the United Kingdom.
