The Map Room

James Cheshire has created migration maps using data from the Global Migrant Origin Database. “Each line shows the origins and destinations of at least 4000 people in a given year (2000 in this case). The more red the line the more people it represents. I have used great circle distance to plot them onto the Earth.”

In the April 2010 print edition of The Atlantic, authors Dante Chinni and James Gimpel “analyzed reams of demographic, economic, cultural, and political data to break the nation’s 3,141 counties into 12 statistically distinct ‘types of place.’ When we look at family income over the past 30 years through that prism, the full picture of the income divide becomes clearer—and much starker.” The resulting maps — available online in an interactive version (Flash required) — show how each of “the 12 states” have fared between 1980 and 2010. More from the designers. Via @replogleglobes1.

If the U.S. migration maps I linked to earlier this month weren’t detailed enough for you, you should absolutely take a look at Forbes’s interactive map, which gives county-by-county information on domestic migration. Actually, it’s more detailed than that: for each county, it shows how many people moved to and from each and every other county in the U.S. (assuming that more than 10 people moved from one county to another) and the average per capita income of the people doing the moving. Based on IRS data, which you might expect. The map dates from last June but I can’t recall seeing it before. Thanks to Jason Hodge for the tip; also via @geospatialnews.

Interactive maps of domestic migration in the United States from the Pew Research Center. “They show gains and losses only from people who move from one state to another, and not from births, deaths or movement to and from other countries, which are the other sources of population change.” Flash required.
