This paper examines whether the gap in fertility between women with higher education and in professional occupations and other women has narrowed or widened over time in Australia. Using data from the Australian Census of Population and Housing 1986, 1996, the paper focuses on levels of childlessness. Both working women (using occupational categories) and all women (using educational attainment) aged between 20 and 44 were examined. Focusing particularly on women working in, or qualified for, some selected high-prestige professions (doctors, lawyers, dentists and vets), as well as on women with other tertiary qualifications and working in other professional or managerial occupations, the findings suggest that, between 1986 and 2006, childlessness has grown at a slower rate for women with tertiary education than for all women, although women with tertiary education continue to have the highest proportion of childlessness. Our findings for working women were similar, with women working in selected prestigious occupations having the highest rates of childlessness of all working women, but with this growing at a slower rate than was the case overall.
