Strange, isn't it ;) ?
Providing birth control
to women at no cost substantially reduced unplanned pregnancies and cut
abortion rates by 62 percent to 78 percent over the national rate:
Among a range of birth control methods offered in the study, most women
chose long-acting methods like intrauterine devices (IUDs) or implants,
which have lower failure rates than commonly used birth control pills.
Unintended pregnancies are a major problem in the United States. Each
year, about 50 percent of all U.S. pregnancies are unplanned, far higher
than in other developed countries. About half of these pregnancies
result from women not using contraception and half from incorrect or
irregular use. The Contraceptive Choice Project enrolled 9,256 women and
adolescents in the St. Louis area between 2007 and 2011. Participants
were 14-45 years of age, at risk for unintended pregnancy, and willing
to start a new contraceptive method.
From 2008 to 2010, annual abortion rates among study participants ranged
from 4.4 to 7.5 per 1,000 women. This is a substantial drop (62 percent
to 78 percent) over the national rate of 19.6 abortions per 1,000 women
in 2008, the latest year for which figures are available. (seems like, 44/196=22 and 75/196=38, yeah ?)
