The number and rate of abortions across the United States have plunged to their lowest levels since the procedure became legal nationwide in 1973, according to new figures released Wednesday. The report from the Guttmacher Institute, a research group that supports abortion rights, counted 862,000 abortions in the U.S. in 2017. That’s down from 926,000 tallied in the group’s previous report for 2014, and from just over 1 million counted for 2011.
