Sugar made Jamaica one of the most valuable possessions in the world for more than 150 years. The British Parliament abolished slavery as of August 1, 1834. After a long period of direct British colonial rule, Jamaica gained a degree of local political control in the late 1930s, and held its first election under full universal adult suffrage in 1944. Jamaica joined nine other U.K. territories in the West Indies Federation in 1958 but withdrew after Jamaican voters rejected membership in 1961. Jamaica gained independence in 1962, remaining a member of the Commonwealth.

Historically, Jamaican emigration has been heavy. Since the United Kingdom restricted emigration in 1967, the major flow has been to the United States and Canada. About 20,000 Jamaicans emigrate to the United States each year; another 200,000 visit annually. New York, Miami, Chicago, and Hartford are among the U.S. cities with a significant Jamaican population. Remittances from the expatriate communities in the United States, United Kingdom, and Canada, estimated at up to $800 million per year, make increasingly significant contributions to Jamaica's economy.
