i think someone's putting the cart before the horse here. i heard this all over the news today and it seemed that every announcer (even the ones on the conservative radio talk station) were saying as if teen sex causes divorce.
the reality is that low socioeconomic status, little or no education, and a general lack of common sense are the root causes. everything else is just spin off or a downward spiral.
those with lower incomes and minimal education tend not to be the most mature people. hence, higher divorce rates. these same circumstances make them less apt to be good parents. hence, their children aren't educated on things like sex. so they go out and do it.
the truth is that whatever is contributing to the higher divorce rates is also contributing to the increased rates of teen sex. that is the only link between divorce rates and teen sex. one does not cause the other by any stretch of the imagination.
