Sarah Kliff reports today that the teen birthrate has plummeted over the past decade. That’s not news. The interesting question is why the teen birthrate has plummeted, and a new paper in the Journal of Adolescent Health says the reason is better access to contraceptives. That sounds reasonable, but Kliff backs up this idea with the following chart, taken from data in the paper:

This is a problem. Contraception use dropped slightly between 2009 and 2012. Sexual activity stayed about the same. And yet teen pregnancies declined by an astounding 20 percent over the same period. This does not fit with the notion that contraception is key.

Plus there’s longer term data. The chart below shows the teen pregnancy rate since 1990. It dropped steadily from 1992 to 2006, despite virtually no change in contraceptive use. I’ve subbed in contraceptive use from the new paper for 2007-12 (dashed line), and it doesn’t really seem to correlate with teen pregnancy rates either:

So count me skeptical about the contraception theory. Teen pregnancy has been dropping for 25 years, and any explanation needs to account for this. But what could it be?

REAL QUICK, REAL URGENT

Minority rule, corruption, disinformation, attacks on those who dare tell the truth: There is a direct line from what's happening in Russia and Ukraine to what's happening here at home. And that's what MoJo's Monika Bauerlein writes about in "Their Fight Is Our Fight" to unpack the information war we find ourselves in and share a few examples to show why the power of independent, reader-supported journalism is such a threat to authoritarians.

Corrupt leaders the world over can (and will) try to shut down the truth, but when the truth has millions of people on its side, you can't keep it down for good. And there's no more powerful or urgent argument for your support of Mother Jones' journalism right now than that. We need to raise about $450,000 to hit our online fundraising budget in these next few months, so please read more from Monika and pitch in if you can.
