Effective air conditioning that became available in the 1950’s has been the reason for the influx of 20 million new residents in Florida.
The whole country is being destroyed by to many people...immigration should have been cut to lower levels fifty years ago and Army troops on the border like the 1930s
Without a doubt that too.
I remember agents of land speculators blanketing the North East selling Florida lots (easy terms, low down payment)
The ability of families to drive to Florida for a vacation also helped folks to see what Florida was like.
Many things came together in the 50s and 60s that encouraged the migration. The large population and the amount of people from the NE were some of the reasons I crossed Florida off my list of “move to” states when I retired. In 2001 I was finally able to say, “See ya” to Fun City and went a little bit South West, over the mountains to WV.
