Indo-Trinidadians and Tobagonians are a subgroup of Indo-Caribbeans, which are a subgroups of the wider Indian diaspora. Generally, most Indians in Trinidad and Tobago can trace their ancestors back to northern India, especially the Bhojpur and Awadh region of the Hindi Belt, which lies in the Gangetic plains, a plain that is located between the Ganga and Yamuna rivers and faces the mountain ranges of the Himalayas and the Vindhyas in Northern India. However, some Indians may trace their ancestry to other parts of South Asia, notably southern India.
