How many abortions are performed at each stage of pregnancy?

Based on the date of the mother’s last menstrual period, the breakdown of abortions is as follows:

Weeks of Pregnancy      Percentage     Yearly total

< 9 weeks                                65.4%                  563,958

9-10 weeks                             14.7%                  126,761

11-12 weeks                           8.2%                    70,710

13-15 weeks                           6.3%                    54,326

16-20 weeks                           4.1%                    35,355

20+ weeks                               1.3%                     11,210

All abortions                          100%                    862,320

This means approximately 88% of abortions occur in the first trimester (first 12 weeks) of pregnancy.

Note: The figures here differ from the total listed on page 30, which is from a preliminary report that does not break abortions down by weeks.
