Despite such debate and difficulties, thousands of women have legal abortions in the United States every year. In 2013, there were approximately 664,000 legal abortions reported in the U.S., a decrease from previous years. State restrictions on abortion may play a part in the decreasing number, but the use of contraceptives has also played a significant role in preventing abortion. It was estimated that in 2014 alone, the use of publicly funded contraceptive services helped to avert 678,000 unintended pregnancies that would have ended in abortion.
Unintended pregnancies among adolescent women can often lead to abortion, given the age of the women. As expected, the number of abortions among teens increases with age, and in 2013 there were 25,148 reported abortions among women aged 19 years, compared to 6,068 among those aged 16 years. Sexual education and the use of contraceptives can be healthy and effective methods of avoiding pregnancy. In 2014, the state of California was estimated to have averted 16,900 abortions among teenage girls through the use of publicly funded contraceptive services.
Public opinion in the U.S. remains divided on the issue of abortion. A survey from May 2016 found 47 percent of Americans considered themselves pro-choice, while 46 percent considered themselves pro-life. Some feel so strongly about the issue that it has led to violence and the threat of violence against those who provide, perform or have abortions. This is seen in the fact that from 1970 to 2015 there were 255 terrorist attacks on abortion related institutions or clinics, making abortion related terrorist attacks the fourth most common type of terror attack over this period.
