Forbes magazine recently updated its excellent American Migration interactive map, which uses data from the Internal Revenue Service Tax Stats to illustrate that approximately 37.5 million Americans move homes every year.
Geographic mobility is one of the main challenges election officials face when trying to maintain the most up to date and accurate voter registration lists possible. Having the most current information about how many people are living in the jurisdiction and their demographic characteristics helps election officials better allocate resources during an election season.
The Forbes map, which details how many people are migrating into and out of every county in the nation, where they are moving to, and their per-capita income, offers a unique picture of this constant mobility.
