Accumulated Income and Fertility
Martin Kolk, Stockholm University
Research on income and fertility has largely focused on either the cross-sectional relationship between income and current number of children, or the income the year before child bearing. In the current study I introduce a novel and superior measure on the relationship between income and earnings in relation to childbearing to asses if poorer or richer individuals have more children. I presented accumulated income histories for men and women in contemporary Sweden for cohorts born between 1940 and 1980 using administrative register data. I show how income is related to completed fertility and parity, for two different operationalization of income; disposable income, and earnings. I show a strong positive gradient between accumulated income for men for all cohorts, and the gradual transformation from a negative to a positive gradient for women.
