It was estimated by the Population Reference Bureau that 37% of the population lived in urban areas in 2001. The capital city, Freetown, had a population of 822,000 in that year.

The prevalence of AIDS/HIV has had a significant impact on the population of Sierra Leone. The United Nations estimated that 7% of adults between the ages of 15–49 were living with HIV/AIDS in 2001. The AIDS epidemic causes higher death and infant mortality rates, and lowers life expectancy.
