This FRONTLINE documentary was first broadcast on PBS on April 18, 1983. It was filmed at a clinic in Chester, Pa., a small city which at that time had a 30% unemployment rate. The clinic was chosen because it was representative of abortion clinics in the United States. The clinic also offered individual counseling in which the reasons behind the decision are explored. During their five months at the clinic, the film's producers met with hundreds of women. The two whose abortions are shown in this film are single, white and young -- as are the majority of women who have had abortions in the United States over the past 30 years.

From producers Mark Obenhaus and Elizabeth Leiter, “The Abortion Divide” offers a window into the sometimes difficult and deeply personal choices women face with unplanned pregnancy – and examines the steadfast belief of the anti-abortion community that there should be no choice at all.

There are brief instances where image and sound meet; however, the majority of the images are overtaken by at times symphonic, at times cacophonous soundtracks which displace the normal filmic viewing experience.
