teen pregnancy rates in the u.s. are at about 41.5 per 1,000 people and dropping, largely due to easier access to contraception, better (i.e., not abstinence-based) sex education, and the advent of internet porn.
by contrast, the netherlands has a teen birth date of 5.3 per 1,000, switzerland 4.3 per 1,000, and germany 9.8 per 1,000. all 3 have even easier access to contraception and more comprehensive sex education, as well as universal health care.
