About 60% of Colombia's population are mestizos, and some one fifth are of European descent. Indigenous peoples, who account for only about 1% of today's population, live on the edge of some of the major cities and in remote areas. About 15% of the people are of mixed African and European descent. The small (less than 5%) black population is concentrated along the coasts and in the Magdalena and Cauca valleys. Spanish is the official language. The population is overwhelmingly Roman Catholic. There are universities in all the major cities.
