New York: Guttmacher Institute and United Nations Population Fund. pp. 17, 19, 27. Some 215 million women in the developing world as a whole have an unmet need for modern contraceptives[...] If the 215 million women with unmet need used modern family planning methods....[that] would result in about 22 million fewer unplanned births; 25 million fewer abortions; and seven million fewer miscarriages....If women's contraceptive needs were addressed (and assuming no changes in abortion laws)...the number of unsafe abortions would decline by 73% from 20 million to 5.5 million. A few of the findings in that report were subsequently changed, and are available at "Facts on Investing in Family Planning and Maternal and Newborn Health" (PDF). Guttmacher Institute.
