Increase in Teen Pregnancy and abortion in 2006

Recently a think tank analyzed the teen birth rates for 2006 and compared to the previous years, the number of teen pregnancies went up for the first time since the 1990s . I read the full report here. They attribute the increase in teen pregnancies to the abstinence only campaign brought about by George W. Bush's presidency. If that's the case, then this pregnancy increase would likely be sustained after 2006 since the abtinence only funding didn't stop after 2006.

So, I did a Google trend search of some terms related to pregnancy and teenagers. I know that this isn't completely scientific, but it stands to reason that if people are searching for the terms that there is a reason for it. See the google search science with flu symptoms and tracking flu outbreaks this past year. Here is what I found. Searches for "teen sex" went way up in 2006 but then went down back to normal after that. A control search for "birth control" remained steady over the years. So what happened in 2006 that made teenagers have a lot of sex but then stopped? Did the number of teenagers that would have had sex anyways reach a maximum that year and they all got pregnant? Unlikely.



There has to be some factor that influenced the teens both to have sex and then to stop. Seeing all their friends getting pregnant and having babies would stop a lot of kids from having unprotected sex, but the search for birth control didn't go up after 2006.

Perhaps the cause of the births in 2006 were the sex parties in 2005?
