Just over a decade ago the documentary The Education of Shelby Knox looked at how pathetically backwards sex education is in the USA. Thanks to documentaries and compounding evidence that asbstinance-only education has no impact on teen pregnancy rates (it does increase STI/STD rates though!) sex education is no different. The USA is catching up with the rest of the developed world when it comes to talking to teens about birth control.
Since 2007, teens have become better informed of their choices around birth control and are using that knowledge.
What changed was how teenage girls used contraceptives. The percentage of sexually active teens who used at least one type of birth control the last time they had sex rose from 78 percent in 2007 to 86 percent in 2012. More teens gravitated toward better types of birth control — like pills, IUDs, or implants — rather than relying on lower-quality birth control like condoms.
