As of 2013, the province had a population of 2,609,486 people. The original inhabitants of the area were
Khoisan, but only a few residual groups remain today, ousted from pastoral land by other groups. In some areas they represent under 2% of the population. Most pastoral farmers in the province are known Nyaneka-Khumbi, but do not form a whole ethnic group. A significant ethnic group in the province is the
Mwila, who originally inhabited the plateau areas. Favored by the relatively mild climate, there was a relatively strong colonization by Portuguese immigrants who sometimes mixed with the local population. This led to expansion and diversification of agriculture at the same time, but also to a growth of cities and towns. However, the influx of IDPs in the thousands during the war severely affected the province. During the war, a considerable number of
Ovimbundu fled to the highlands of the province of Huíla. In some areas they now represent some 37% of the population, with the largest concentration in the central highlands. There is now also a much smaller number of
Bakongo who had been assimilated from the Congo, and some settled in the province upon their return. The
Heroro represent about 0.5% of the population. ==List of governors of Huila==
