In <a href=\"https:\/\/en.wikipedia.org\/wiki\/Brazil\" target=\"_blank\" rel=\"noopener\">Brazil<\/a>, the strong influence of individual socio-economic factors on race\/colour self-classification is well known. With the expansion of genomic technologies, the use of <a href=\"https:\/\/en.wikipedia.org\/wiki\/Genealogical_DNA_test\" target=\"_blank\" rel=\"noopener\">genomic ancestry<\/a> has been suggested as a substitute for classification procedures such as self-declaring race, as if they represented the same concept. We investigated the association between genomic ancestry, the racial composition of census tracts and individual socioeconomic factors and self-declared race\/colour in a cohort of 15,105 Brazilians. Results show that the probability of self-declaring as black or brown increases according to the proportion of African ancestry and varies widely among cities. In <a href=\"https:\/\/en.wikipedia.org\/wiki\/Porto_Alegre\" target=\"_blank\" rel=\"noopener\">Porto Alegre<\/a>, where most of the population is white, with every 10% increase in the proportion of African ancestry, the odds of self-declaring as black increased 14 times (95%<a href=\"https:\/\/en.wikipedia.org\/wiki\/Confidence_interval\" target=\"_blank\" rel=\"noopener\">CI<\/a> 6.08\u201332.81). In <a href=\"https:\/\/en.wikipedia.org\/wiki\/Salvador,_Bahia\" target=\"_blank\" rel=\"noopener\">Salvador<\/a>, where most of the population is black or brown, that increase was of 3.98 times (95%CI 2.96\u20135.35). The racial composition of the area of residence was also associated with the probability of self-declaring as black or brown. Every 10% increase in the proportion of black and brown inhabitants in the residential census tract increased the odds of self-declaring as black by 1.33 times (95%CI 1.24\u20131.42). Ancestry alone does not explain self-declared race\/colour. An emphasis on multiple situational contexts (both individual and collective) provides a more comprehensive framework for the study of the predictors of self-declared race\/colour, a highly relevant construct in many different scenarios, such as public policy, sociology and medicine.<\/p>\n<p>Read the entire article <a href=\"https:\/\/doi.org\/10.1371\/journal.pone.0216653\" target=\"_blank\" rel=\"noopener\">here<\/a>.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>We investigated the association between genomic ancestry, the racial composition of census tracts and individual socioeconomic factors and self-declared race\/colour in a cohort of 15,105 Brazilians.
