The total number of surgical abortion clinics in U.S. fell 12% to 582 in 2013 - a 73% decline from a high of 2,176 in 1991.
Texas led all states with 11 closures in 2013, most of which shut down after Texas passed an abortion law earlier this year that required abortionists to maintain local hospital privileges. New clinic safety rules in Pennsylvania and Maryland also prompted closures in those states.
"The numbers don't lie. A 73% drop in surgical abortion clinics is a significant loss. We are witnessing the death throes of the abortion cartel," said Troy Newman, president of Operation Rescue, which conducted the study.
"We have been teaching for the last two decades that abortion collapses under its own weight, and that the weak point is precisely the abortion mill," Father Frank Pavone, National Director of Priests for Life said, reacting to the record number of closures.
"In this year when the horrifying nature of the abortion industry came to light in the Gosnell trial and when so many state laws increased the standards for abortion mills, we see that coming true more than ever," Father Pavone said.
"Knowing there are so many children having birthdays in 2014 who might never have been born convinces us that applying pressure to clinic operators and abortionists is a vital part of our work to end abortion," he added.
Of 87 clinics that discontinued surgical abortions, 81 are permanently shuttered while 6 abortion businesses ceased surgical abortions, but continued to sell that abortion pill. The figures do not include the 11 abortion clinics that were closed temporarily in 2013, then reopened later in the year.
