Include foreign born by place of birth (nationality) in addition to region
Thanks for the suggestion! The large number of columns for that table (with the relative sparseness) makes it hard to do systematically for each place.
There's also the problem that showing the most common places can actually be kind of boring (see http://www.slate.com/articles/arts/culturebox/2014/05/immigration_map_what_are_the_biggest_immigrant_groups_in_your_state.html) but if we are careful, we should be able to work around that.
In general, I think the direction for this is to add some new pages for places, instead of jamming more on the current profile page. We've talked about having "detailed profile pages" for each of the major categories (demographics/economics/etc) but we could organize them around other principles as well.
For now, if you didnt know, you can click on "show the data" under the "Place of birth for foreign-born population" chart, and then click on "view table" and see what you're asking for, although not in a chart.
