Red lines on the map show movement from one county to another (the map even shows the county they go to) while black lines show movement into the county.
You can enlarge the map to focus on a specific area – although then you lose the complete US perspective. The width of the lines of migration (the black and red lines) indicates number of migrants – wider means more people moving.
Hovering over one of the lines of migration that lead to a county of your choice with your mouse shows the number of individuals moving into or from the county, as well as the per capita income for each group.
You can even ‘share’ the map showing migration patterns by clicking the ‘share’ button.
This could be an interesting tool to see migration patterns, especially when you look at the Northeast, major Midwestern cities, and Los Angeles. The information on this map could lead to interesting discussions on why people move, where they move, and the effect on the culture, economy, and politics of where they move from and move to.
Think of the possibilities!!!
