For the 1994 to 1997 data years, a large number of abortions were reported to the Therapeutic Abortion Survey without any information on the age of the female. Age groups have now been estimated for induced abortions at the Canada, provincial and territorial level. As a result of these new estimations, any previously released age group statistics at the Canada level will not match the latest Canada level statistics.

Percentage distribution of induced abortions across age groups, excluding abortions with no reported age.
