Over at Acontece, I found a list (in PT) from 2002 of Brazilians living abroad (estimated at over 2 million). The list is quite long so I’ll borrow the section with the highest numbers. So if you are looking to move somewhere and wish to know more or less how many Brazilians live there, this list is a good place to start. If you are looking to get in touch with the local communities, Brasileiros no Estrangeiro is a nice source. If you are curious where Ciudad del Este is, it’s in Paraguay.
Within the US, the image below from ePodunk shows partial data from the year 2000 on the percentage of Brazilians vs. other residents by city (see link for the rest of the list).
