Researchers credit better contraception (including long-acting methods) alongside declines in teen sexual activity — a sustained, all-groups win that rarely makes headlines.
US teen births have fallen 78% since 1991 — from 61.8 to 13.9 births per 1,000 teens — one of the biggest public-health wins almost nobody talks about.
