There are just shy of 50 million people, age 65 or older, living in the United States, according to the Census.
That number, by 2060, is expected to double. Already, 54.8% of residents of Sumter County, Fla.–the most populous state for 65-plus year-olds at 19.4%–are over the age of 65. The Villages, a Sumter County, Fla., retirement community, has a population of 118,891 (as of July 1, 2015).
