The country has an area of 83,000 square miles and a population of 766,000. Data from a 2002 census on religious affiliation indicate that approximately 57 percent of the population is Christian, broken down as follows: 17 percent Pentecostal, 8 percent Roman Catholic, 7 percent Anglican, 5 percent Seventh-day Adventist, and 20 percent other Christian groups. Approximately 28 percent of the population is Hindu, 7 percent is Muslim (mostly Sunni), and 2 percent practice other beliefs, including members of the Rastafari movement and the Baha'i Faith. An estimated 4 percent of the population does not profess any religion. Some religious groups claim higher membership than reflected by the 2002 census.
The country is ethnically diverse, reflecting East Indian, African, Chinese, and European ancestry, as well as a significant indigenous population. Most religious groups can claim membership from a cross section of ethnic groups, with two exceptions: Most Hindus are Indo-Guyanese, and nearly all Rastafarians are Afro-Guyanese.
