The National Center for Health Statistics does not track the number of abortions. Abortions are tracked through CDC’s Abortion Surveillance System and reported annually in the Morbidity and Mortality Weekly Report.
Reports covering 1979 through the most current report are located at the above link. Typically, these reports are published in the last week of November and lag three years.
