This paper examines a number of demographic and sociocultural factors (e.g., age, marital status, family size, religion, religious assiduity, sex-role ideology) as predictors of women's attitudes toward abortion, using data from the Canadian Fertility Survey of 1984. The findings suggest that women's abortion attitudes are to a greater extent based on ideological positions. It appears that anti-abortion stance affects those women who are religious, presumably by increasing the relationship between their general sex-role ideological stances and abortion attitudes. Abortion attitudes also vary according to a woman's education, her size, and province/region of residence.
