The article analyzes the patterns of comparative mortality of Cali and Valle, between the Afrodescendant and white-mestizo population, by sex and age groups, based on the metadata of deaths in the 2005 Census and the death certificate of the year 2010. The findings reveal strong differentials by age structures of deaths (pyramids) and the cumulative mortality, which are conclusive of unequal mortality patterns between the two populations, both in Cali and Valle. This evinces demography of social inequality based on ethnic-racial component.16 131167
