Abortion incidence and access to services in the United States, 2008.

Context: The incidence of abortion has declined nearly every year between 1990 and 2005, but this trend may be ending, or at least leveling off. Access to abortion services is a critical issue, particularly since the number of abortion providers has been falling for the last three decades.

Methods: In 2009 and 2010, all facilities known or expected to have provided abortion services in 2007 and 2008 were contacted, including hospitals, clinics and physicians' offices.
