Guyana continues to be influenced by British and Indian culture as well as the cultures of the United States, Europe, Africa, the Islamic world, East and South Asian countries, and Latin America, especially the neighbouring countries of Venezuela and Brazil.

The largest ethnic group are the Indo-Guyanese, the descendants of indentured labourers from India, who make up 39.8% of the population, according to the 2012 census.

[11][12][13][14] Most Indo-Guyanese are descended from indentured labourers who migrated from North India, especially the Bhojpur and Awadh regions of the Hindi Belt in the present day states of Uttar Pradesh, Bihar and Jharkhand.

[15] A significant minority of Indo-Guyanese are also descended from indentured migrants who came from the South Indian states of Tamil Nadu and Andhra Pradesh.

[16] Among the immigrants there were many labourers from other parts of South Asia such as Nepal, Bengal, Chota Nagpur, and Northwestern India - the modern states of Punjab, Haryana - which was at the time a part of the state of Uttar Pradesh and Rajasthan.

[22][23] Portuguese is increasingly widely used as a second language in Guyana, particularly in the south of the country near the Brazil border.

[24] The religious breakdown of Guyanese people is: Hindu 28.4%, Pentecostal 16.9%, Roman Catholic 8.1%, Muslim 7.2%, Anglican 6.9%, Seventh-day Adventist 5%, other Christian denominations 20.5%, no religion 4.3%, Rastafarian 0.5%, Bahá’í 0.1%, other faiths 2.2%.
