The New York Times has another fabulously detailed interactive map in its series on immigration. This one shows countries of origin for foreign-born workers in the US.
Here are the top ten countries, with the top occupation for each nationality in parentheses:
1. Mexico - 5,286,400 (skilled construction workers)
2. Philippines - 848,800 (clerical and administrative staff)
3. India - 746,200 (computer software developers)
4. China - 653,000 (cooks and food preparers)
5. El Salvador - 580,100 (cooks and food preparers) (and consider, by the way, that the population of El Salvador itself is only about 7 million)
6. Vietnam - 526,000 (hairdressers and grooming services)
7. Germany - 476,100 (clerical and administrative staff)
8. South Korea - 408,400 (sales)
9. Cuba - 399,300 (clerical and administrative staff)
10. Canada - 364,900 (managers and administrators)
You can also create maps and tables that show foreign workers within given occupations. The New York Times really needs to be given some kind of medal for consistently creating the most information-rich map graphics anywhere.
