We’ve been looking at what cities immigrants are flocking to. But international migration is just one part of the story of population change.
Another part is natural increase — how many births there are, offset by how many deaths there are. This map, using data from the U.S. Census, shows the number of births minus number of deaths per 1,000 people in each county in the U.S. that happened in the year between July 1, 2012 and July 1, 2013.

And here’s deaths per 1,000 people:
