Metro Migration

01

This map shows the movement of people between US population centers.

It aggregates migration data by metro area, and then shows the flows into a metro using blue and the flows out using yellow. This allows you to get a sense of both the overall strength of the connections between metro areas, and the net direction of flow.

If you find a cool pattern, tell me about it in the comments!

    Hi Robert,

    I came across your visualization after finding your name through Data Science for Social Good. I was wondering if you’ve been able to examine how these migration patterns look when accounting for educational attainment. For example, San Francisco has large out-migration of lower educated individuals by higher in-migration of highly-educated individuals (http://www.citylab.com/work/2014/06/high-school-dropouts-and-college-grads-are-moving-to-very-different-places/372065/). Just wondering if you had any insight along these lines.

    Best,
    Matthew Castillon

    Hi Matthew–

    Sorry it’s taken me so long to respond to this! Looking at how migration varies by education (and other demographic characteristics) is one of the things I’d really like to be able to do. I suspect you’d be able to see really striking trends like the one you mention for SF. And I imagine that the age distribution might differ a lot by flow–all the people moving to Phoenix, for example.

    Unfortunately the data that the IRS has released doesn’t have any demographics in it. Supposedly it may be possible to ask them nicely and get that information, but I haven’t tried that yet. On education and migration specifically, one paper I know of came to the conclusion that college graduates are more likely to move long distances for work http://jhr.uwpress.org/content/45/4/944.short.
