A record number of abortion clinics in the United States closed during 2013.

The survey from Operation Rescue says the number of surgical abortion clinics in the United States is down 12 percent in 2013 and down 73 percent from a record high in 1991.

In all, 87 clinics discontinued surgical abortions.  Six of the clinics remained open to provide abortion-inducing drugs but 81 clinics completely closed their doors.  The total does not include clinics that were closed for significant portions of time in 2013.

The number of clinics that only provide abortion-inducing drugs remained fairly steady at 176, with six documented clinic closures.

Planned Parenthood clinics accounted for 30 percent of surgical abortion clinics and 93 percent of all clinics that offer abortion via drugs only.  Planned Parenthood, which receives tax dollars, is responsible for about one third of all abortions in the United States.
