The demographics of Sierra Leone are made up of an indigenous population from 18 ethnic groups. The Temne in the north and the Mende in the south are the largest. About 60,000 are Krio, the descendants of freed slaves who returned to Sierra Leone from Great Britain, North America and slave ships captured on the high seas. In the past, some Sierra Leoneans were noted for their educational achievements, trading activity, entrepreneurial skills, and arts and crafts work, particularly woodcarving. Many are part of larger ethnic networks extending into several countries, which link West African states in the area. Their level of education and infrastructure have declined sharply over the last 30 years.

note: on 21 March 2022, the US Centers for Disease Control and Prevention (CDC) issued a Travel Alert for polio in Africa; Sierra Leone is currently considered a high risk to travelers for circulating vaccine-derived polioviruses (cVDPV); vaccine-derived poliovirus (VDPV) is a strain of the weakened poliovirus that was initially included in oral polio vaccine (OPV) and that has changed over time and behaves more like the wild or naturally occurring virus; this means it can be spread more easily to people who are unvaccinated against polio and who come in contact with the stool or respiratory secretions, such as from a sneeze, of an "infected" person who received oral polio vaccine; the CDC recommends that before any international travel, anyone unvaccinated, incompletely vaccinated, or with an unknown polio vaccination status should complete the routine polio vaccine series; before travel to any high-risk destination, CDC recommends that adults who previously completed the full, routine polio vaccine series receive a single, lifetime booster dose of polio vaccine
