The question is why? Approach: This study, using multiple linear regression, examines whether women’s unprotected sexual activity is deterred by the risk of contracting AIDS as reflected in decreased abortion rates. Results: The empirical evidence consistently finds that the prevalence of AIDS reduces the risky (unprotected) sexual activity of women of childbearing ages 15-44 as reflected in their abortion rates. The empirical results remain robust for the abortion rates of teens ages 15-17 and for teens ages 15-19. Conclusion: The empirical results suggest that the behavioral modification induced by the prevalence of AIDS accounted for 21% of the decrease in abortion rates over the time period 1992-2005.
