The largest concentrations of Afro-descendent populations and, to a lesser extent, indigenous populations, at both the national level and in the capital, are found in the areas with the lowest levels of economic and human development, according to estimates made in 2005.
根据2005年的估计数，在全国和在首都，经济和人类发展水平最低的地区非洲裔人口最为集中，土著人口也在较小程度上集中于这些地区。
