The figures you have presented seem to have discrepacies . These are from Wikipedia and show that there are close to 10 times as much Colombians as you stated in your figures of 17,576 for 2010 . Colombians are a huge expat population here and the official figures from 2010 were that there were 177.000 people . How did you come up with 17,576?

The USA does not even appear on the top 16 as per this same list . I do not believe that there are close to 20.000 USA born people living in Argentina of non argentinian descent . All the expats I know have mentioned that the USA expats who moved here before 2010 most have returned . I would be very surprised that in the whole of Argentina there are more than 5,000 usa born citizens without argentinian parents living here full time . In Buenos Aires it would be at most 2000 people .
"According to the
INDEC 1,531,940 of the Argentine resident population in 2001 were born outside Argentina, representing 4.22% of the total Argentine resident population. In 2010, 1,805,957 of the Argentine resident population were born outside Argentina, representing 4.50% of the total Argentine resident population. (I added this paragraph)
