The ethnic groups are Kakawira which represents 0.07% of the total country's population, Nawat (0.06%), Lenca (0.04%) and other minor groups (0.06%).

There is a small Afro-Salvadoran group that is 0.13% of the total population, with Blacks, among other races, having been prevented from immigrating via government policies in the early 20th century.
