What areas have been the main sources of immigrants in recent years?

I believe the correct answers are Asia and Latin America.
When it comes to America especially, there are a lot of immigrants (who are usually illegal immigrants) from Latin America - countries such as Mexico, Cuba, etc. On the other hand, many Asian immigrants also come to America - the Chinese, the Japanese, etc. Asian immigrants such as those from Afghanistan, Iraq, etc. are now increasingly coming to Europe to get away from wars.
