This document discusses teenage pregnancy in the United States. It notes that most teens would be upset if they became pregnant but many have unprotected sex. Each year over 600,000 US women aged 15-19 become pregnant. Teen pregnancy rates have declined in recent decades but are still higher than in many other developed countries. Abstinence-only sex education is less effective than comprehensive sex education in preventing teen pregnancy. When contraceptive use and abstinence are both discussed, it is more effective at reducing risks.
