The Guttmacher Institute research shows that The U.S. abortion rate declined 14% between 2011 and 2014, reaching a record low.
The evidence suggests that CONTRACEPTION and fewer unintended pregnancies played a larger role in these most recent declines than new abortion restrictions. Well over 60% of the decline in the number of abortions occurred in states WITHOUT new restrictions. In other words, States that allow greater access to contraceptive services (read: Planned Parenthood) have far less abortions. It's really a no-brainer, but apparently there are a lot of people who aren't using there's when deciding on these measures.
