An April 24 article in the Rocky Mountain News states:

The University of California School of Public Health estimated that before 1966, an estimated 5,000 to 10,000 women died each year in the U.S. from complications of illegal abortions.

Trying to find out more about this study, I found that it was cited in a 1966 book by Lawrence Lader, Abortion. (See note 21 here for a secondary citation.)

Do any readers have additional information about this study, or know of additional research on the levels of pre-1967 maternal deaths from illegal abortion in the U.S.

Please confine your comments to this factual issue, and do not argue the broader pro/con merits of the abortion question.
