Average Latin American Racial Admixture Divided by Regions!

[Erronkari]

Thanks!

Gran Chaco was by far the hardest one, because the few results I've found either had them as mostly Amerindian while a one study had them as balanced Mestizos.

What do you think?

Yes! Good point!
The results are reliable because it's a very diverse region.
"Gran Chaco" known as "Region Chaqueña" is integrated by the entire provinces of Formosa, Chaco, a big portion of Santiago del Estero, extreme north of Santa Fe and the extreme eastern area of Salta Province.
I imagine there are samples of all those regions.
The eastern area of Formosa is similar to Paraguay, around 65% Euro while the Eastern area of Chaco province and North of Santa Fe are around 70% Euro.
These areas are more Euro influenced because people are more similar to pampean region, I'd say, the bulk are partly European recent descendants mixed with less colonial contribution (oh well, some other individuals re balanced immigrant descendants+colonials).
The rest of the region is integrated by almost pure colonials, with some less immigrant roots, but predominantly the first element.
In the case of Santiago del Estero are on average 55% Euro, similar to Central Formosa and Central Chaco.
And finally in the west of Chaco and Formosa and the east side of Salta are very Amerindian influenced.
Indeed there still live some pure/almost pure Amerindian tribes.
But in the towns, were probably people were tested you can find individuals which can score between 35% to 50/55% Euro.
So, as you see depending where the samples come results could be extremely diverse and random.

This is all based on extensive genetic research on different regions of Latin America that was available. This research is rare as hell and hard to track so I couldn't include every country but these are averaged out estimates based on different sources I was able to find. Not everything is completely accurate but it's accurate enough to give you a realistic average of each region.

What do you think?

Good work, but I would add that the Colombian Andean region also overlaps, or better said, is identical to the Venezuelan Andean region. And Puerto Rico also overlaps with Venezuela in general.

It is a shame that there are not recent genetic autosomal studies about the Venezuelan population like in other Latin American countries. I guess that the shitty Chavist/Madurist involution has kept this country isolated from the rest of the western world. There is no Google Earth, there are no serious autosomal studies of its general population, and so on

Thank you Chavez and Maduro!

Brazil seems about right, but Euro admixture is a bit overestimated in regions outside the South and Amerindian is slightly overestimated in South and Northern Brazil.

Well, partly yes, probably the pampean region according some exams is a little more Euro, around 80%/82%, and Chaco region, around 5% more, but the last it's difficult to test because it's a very diverse region ethnically talking.
The rest seem totally agree with most of studies...

Amerindian in Rio Grande do Sul is very strong. It is the mainly colonial imput in almost all white gaúchos. The portuguese crown used to incetive marriages between native women and azoreans imigrants's son and grandsons in the XVIII century. Only in Pelotas you will find a strong african component. Santa Catarina had very few slaves, and it was only about Florianópolis. The countryside is very white. About Paraná I don't know. The average northeasterner is more african than that averages show (I think it is like 55% euro 35% african and 10% amerindian).

I perceived some black influence in Porto Alegre as I remember, but it's obvious because it's a State capital city, and as I remember it wasn't a strong influence either.
And if we consider how is P.A. genetically talking many studies messure it as around 83/86% Euro on average... it's an extremely high Euro % for an important city.

Obviously, in recent times, there are a lot of internal migration too.

Yep. The average Northeasterner is more African. I agree with the percentages you showed. I also think Southeast is slightly more African. It would be important to post the average East Asian and especially West Asian contribution in the Southeast, though. I agree with the European input of South Brazil (around 80%), but I would change places between Amerindian and SSA averages. The African ancestry is simply too strong in Brazil overall, and there have been massive waves of Northeasterners to South Brazil in recent decades. There's also Haitians and other Africans (but they are not too significant for now). My estimate averages for Brazil would be as follows:

North Brazil: 51% Euro / 32% Amerindian / 17% SSA
Northeast Brazil: 55% Euro / 35% SSA / 10% Amerindian)
Center-West Brazil: 58% Euro, 24% SSA / 18% Amerindian)
Southeast Brazil : 62% Euro, 25% SSA, 8% Amerindian / 4% Recent West Asian / 1% East Asian
South Brazil: 82% Euro / 10% SSA / 8% Amerindian
