The term references a swath of states in the southern and southwestern United States that experienced substantial population and economic growth starting in the mid-20th century. This region, characterized by a warm climate, includes states like Florida, Texas, Arizona, and California (though the term is more often applied to Southern California rather than Northern California). It became a significant area of migration and development, drawing people from the Rust Belt and other parts of the country seeking new opportunities.
The rise of this region transformed the political landscape, shifting power away from the Northeast and Midwest. Its economic expansion, fueled by industries like aerospace, defense, and tourism, created a demand for labor and attracted investment. Furthermore, the cultural impact was considerable, influencing national trends in lifestyle, politics, and demographics, contributing to a more conservative political ideology in many areas.
