I remember that this was the subject matter of literally one of the very first threads on the Internet I ever read regarding politics.
There is a direct correlation between the level of a region's religiosity and the average age of first pregnancy - a negative one: the more religious, the lower the age. There's also one between religiosity and divorce rates, and divorce rates and age of pregnancy.
The reason is simply - young girls in these regions who get pregnant at a young age are pressured into marrying young, which very frequently ends badly.
There is a
direct correlation between cold-weather-jacket sales and murder rates - a negative one: the more cold-weather jacket sales, the lower the murder rate. There's also one between murder rates and sunblock sales, and between sunblock sales and school attendance.
The reason is simply - murderers in those regions are more likely to go out and buy sunblock after they commit murders, which in turn depresses cold-weather-jacket sales. Obviously children are thus frightened by the amount of sunblock on playgrounds, and thus stay home from school.
