A new CDC study confirms that during the last 30 years, teen sex has dropped sharply, and birth control use has increased dramatically. (H/T: Marginal Revolution) One result is a massive 57% drop in the teen birth rate during that time, a very positive development.

76% reported just 1-3, with 1 being the top answer.
