How did the widespread availability of air conditioning in the mid 20th century affect migration patterns in the US?

The widespread availability of air conditioning in the mid-20th century significantly influenced migration patterns in the U.S. by making hotter, previously less hospitable regions more comfortable for living and working. This led to increased migration to the Sun Belt states, such as Florida, Texas, and California, as people sought warmer climates while enjoying the benefits of modern cooling technology. Consequently, this shift contributed to economic growth in these regions and altered demographic trends across the country.
