Bumping this to post this map. Here is an ethnic map of Colombia, based on 2018 census data.
Actually it is more ethnic self-identification, with the options presented being "indigenous", "Roma", "Raizal", "Palenquero", "black/Mulatto/Afro" and "no ethnic group". The vast majority (87.6%) didn't identify with any ethnic group, so I somewhat simplistically labelled them as "mestizo/white". 6.7% identified as Afro, down from a bit over 10% in the 2005 census, and 4.3% as indigenous.
Chocó (Afro), La Guajira, Amazonas, Guainía, Vaupés and Vichada (indigenous) are the only departments with an ethnic minority majority/plurality. San Andrés/Providencia is 43% none and 42% Raizal, Cauca is only 54.5% none.
Is there no German-Colombian/Basque-Colombian/Lebanese-Colombian/etc-Colombian sentiment at all?
