42% of Urban Kids have sex by 14

This is very disturbing.

The study, published in The Archives of Sexual Behavior, examined the sexual habits of 2,311 Baltimore youths. But Ompad said, "I don't think other cities would be too different."
The study showed that 42% had engaged in ... intercourse by the age of 14. About 14% of kids said they had sex before the age of 13, a 9% jump from a similar survey by the Centers for Disease Control in 1995.

I hope suburban and rural youth are faring better (i.e. holding off longer) but I have a sinking feeling this is a sign of the times.
