Actually, there's no requirement that
any percentage of TV's residents be under 55. There
is a minimum percentage required for 55 and over, though. Confusion about age restriction in 55+ communities is common, but per federal law, it goes like this: at least 80% of the units must be occupied by someone 55 or older. That's it. The Villages, and any other 55 and older development, can do whatever they want with the remaining 20%. They can make it all 55+ or all under 55 or any combination they choose.
As someone under 55 who lives with a parent in TV and reads the news daily, I feel like a disproportionate number of residents who get in serious trouble here are under 55 and living in a parent or other relative's home. That being said, considering the size of TV, there's very little crime of any sort. I think TV is an incredibly safe, quite, and friendly place, relative to the rest of the country, and I bet you won't regret buying here!
