This map is useless. It shows net domestic migration, but has no information on international arrivals. New York is growing even as the map says it's shrinking because it's the number one destination of foreign immigrants. We'd need to know a lot about foreign migration levels and education to make the kind of conclusions people are proposing from this map.
