Havana is the capital city with a population of 2,184,995 in 1996. In 2001 the nation�s population was around to be 11,184,123.

Cuba's original inhabitants likely came to the island from South America. They were the Guanahatabey and the Ciboney, the former living in the extreme west of the island, the latter in various places in the island and particularly on the cays to the south. Both were hunter-gatherers. The Taino (Arawakan Indians), who arrived later and who spread over not only Cuba but also the rest of the Greater Antilles and the Bahamas, lived in villages and had rudimentary agriculture; they also made simple pottery. The Taino constituted 90 % of the island's population at the time of the Spanish conquest.

Cuba is a multiracial society with a population of mainly Spanish and African origins. The largest organized religion is the Roman Catholic Church, but evangelical protestant denominations are growing rapidly. Afro-Cuban religions, a blend of native African religions and Roman Catholicism, are widely practiced in Cuba. Officially, Cuba has been an atheist state for most of the Castro era. In 1962, the government of Fidel Castro seized and shut down more than 400 Catholic schools, charging that they spread dangerous beliefs among the people. In 1991, the Communist Party lifted its prohibition against religious believers seeking membership, and a year later the constitution was amended to characterize the state as secular instead of atheist.
