Population
The 2009 estimate of Sierra Leone's population is 6.4 million. At the end of 2007, Sierra Leone had a population of 8,700 refugees(a person seeking a state of safety, protection or shelter in another country). Nearly all of the refugees were Liberian. There are officially fourteen ethnic groups in the country. The two largest and most dominant groups are the Mende and Temne. Each group comprises 30% of the population. The life expectancy(the chances of survival according to statistical tables) of Sierra Leoneans is 41 years.
Languages
English is the official language. It is spoken in schools, government administration, and is used by the media. Three other languages are present: Mende, Temne and Krio. Mende is mostly spoken in the south, Temne in the north. Krio is the principal spoken language of about 10% of the population but is understood by 95%.
Religion
The religious diversity of Sierra Leone has seldom(not often) led to conflict. Followers of Islam are estimated to make up 60% of the population. About 30% of the population are Christians. About 10% follow only African indigenous(native to a region) religion. Only small numbers of people have other faiths like Bahāʾī, Hinduism, and Judaism.
