>>10913509>Little known fact, the area where the rio de la plata meets the Atlantic Ocean (Buenos Aires/ Montevideo) wasn’t inhabited by many natives when the Spanish arrived, hence the limited admixture with squatemalan brown types.I don't think that's the reason. Unlike the US and for better or worse we have a highly centralized population. As most if not all exports go through Buenos Aires, the city sprawled like crazy, the result being roughly third to a half the population resides in that tiny space.
Not taking into account the south, most white people are here. Why? that's where the later European migration waves decided to set shop there.
Argentina is, historically, not much different from other Latin American countries. The only god-sent exception is that we got rid of our niggers a long time ago.
It was however a place of interest for 19th and 20th century Euros to come start a new life.
In short, Argentina was bleached. As of recently, this effect is being reverted as we are being flooded by our neighbors and brown people's birth rate is always higher.
