Do parental resources moderate the relationship between women's income and timing of parenthood?

Abstract

Previous research has concentrated on the associations between higher incomes and delayed entry into parenthood, disadvantaged family background and early childbirth, and the availability of public childcare and fertility. This paper examines the extent to which parental resources moderate the relationship between women's income and entry into parenthood, comparing two countries with very different levels of public family support: Finland and the United States. We use Cox regressions with data from the 1979 US National Longitudinal Survey of Youth and the Finnish Census Panel data to demonstrate both striking similarities and differences between the two countries. First, high-income women from disadvantaged backgrounds postpone entry into parenthood in both countries. Second, high parental resources are associated with postponed entry into parenthood among low-income women. However, we find differences between the two countries regarding which parental resource is most influential. While parental income is important in the US, parental education matters most in Finland.
