One of the biggest minority ethnic groups are the Fula at around 3.8% of the population. Descendants of seventeenth- and eighteenth-century Fula migrant settlers from the Fouta Djalon region of Guinea, they live primarily in the northeast and the western area of Sierra Leone. The Fula are virtually all Muslims at over 99%. The Fula are primarily traders, and many live in middle-class homes. Because of their trading, the Fulas are found in nearly all parts of the country.
