Frostbelt-Sunbelt shift

The Frostbelt-Sunbelt shift refers a demographic trend in the United States that began in the 1950s and accelerated in the 1980s whereby population has slowly migrated from the traditionally-dominant North to the previously rural and underdeveloped South.

This shift has had significant economic and political consequences for the United States as a whole, particularly as concerns the Electoral College.
