Sorry if this has already been pointed out, but teen pregnancy rates are now quite a bit
lower than they've been most of this century, so teen pregnancy is not exactly a
new epidemic and nor can we attribute it to anything culturally recent.
This decline is is the case both for the rate of girls who get pregnant and those who actually give birth -- so abortions have also decreased in the last 30 years or so.
I believe there was a peak in teen pregnancy rates in 1991 and the rates have declined about 40 percent since then. But even farther back, there was a larger peak in the 50s and 60s at about 95 births per 1000 teens 15-19 (today the number is closer to 50 births per 1000 teens). (n.b. there's been a little blip in the last 2 years & it's risen by a small amount -- nobody is quite sure why & whether it might be an issue of statistical reporting or something else).
So there are, simply stated, FEWER teens today having babies than in the past. But what has actually changed is the percentage of teens who are giving birth
unmarried. That has risen dramatically. Some of that was likely teens on the higher end of that age range who got married right out of high school. And a lot of it would have been the intense atmosphere of coercion and shame driving pregnant girls into marriage. Which I for one don't think we should be bringing back.
As a side note, the reason so many people seem to think it's "obvious" that so many more teens today (not true) are having babies is because it's much more out in the open. We don't lock up our daughters when they start "showing" or take them out of school and send them off to reformatories for "wayward" unwed mothers (or ... as they used to say, to "visit relatives"

). Pregnant teens just live their lives, they go to high school (hopefully), they go out in public -- heck, sometimes they even have baby showers. And hey -- it doesn't seem to have led to the downfall of civilization that we no longer punish, shame, and hide pregnant teens -- the birth rate for teens has gone down, hasn't it?
This thread is interesting to me on a number of levels -- it's interesting that many folks assume that teen pregnancy is more common now than it was in the past when they grew up. (despite the recent blip of a few percentage points, I can guarantee you that teen pregnancy rates were much higher when you grew up, whenever that was, since the blip basically puts us back to the rate we were at at around 2001, and any time before that, it was much higher). It's also interesting that folks agree that there is some kind of cultural shift or attitudinal change or something that is oh so obviously reflected by the massive numbers of teens these days who are going off and getting preggers (since they aren't actually doing so at a higher rate than before, it's a moot point).
Finally, it's also interesting that the thread is titled the way it is ... "why do teenagers have babies". Really? Is that really the question you want to ask? Because I think the answer is pretty obvious, empirically. Female teens have sex or engage in some other activity involving sperm, sperm meets egg, conception occurs, then somehwere down along the line, she decides whether or not to get an abortion, and if she doesn't and all goes well, she has a baby. Right? Or is the question meant to be asking something else?
