According to this article, Florida has has the third-highest number of missing kids, behind only California and Texas. It also has the third-largest number of registered sex offenders, at a little over 50,000.
I’m not sure how much this actually means, though. Wikipedia says Florida is the fourth most populated state, behind California, Texas and New York, so it would stand to reason that they’d have more missing kids and more sex offenders. (No word on where New York ranks in the number of missing children.) Another thought: a significant number of missing children are teen runaways. It seems like there would be more teen runaways from warmer states (again, Florida and Texas, and southern California too) because they could sleep rough without fear of inclement weather.
I’d like to see how many missing kids per capita there are. The article does say that while Florida has almost the largest number of sex offenders, they’re actually ranked at number thirteen for sex offenders per 100,000 people. They have 281 sex offenders per 100,000; the nationwide average is 223.
