The two main ethnic groups are the Mende, who speak a Mande language and live in the central and southern parts of the country, and the Temne, who speak a W Atlantic language and live in the north. There are also Creoles or Krios, descendants of freed slaves from North America, the West Indies, and other parts of W Africa. The population also contains small numbers of South Asians and Lebanese, who play a major role in the nation's commerce. English is the country's official language and Krio, a mixture of several African languages and English, is the lingua franca. About 60% of the population is Muslim, 30% follows traditional religious beliefs, and 10% is Christian.
