Abstract

In this article, I present the ownchild command, which calculates age-specific fertility rates using an advanced version of the own-children method, originally proposed by Grabill and Cho (1965, Demography 2: 50–73). ownchild provides a graphical representation of average fertility patterns by age over the last 15 years, generates weighted estimates for population subgroups, enhances accuracy by restricting calculations to biological connections between children and their mothers, and delivers 15 reproductive measures. These measures include total and net fertility rates, mean age at childbearing, the percentage of teenage pregnancies, the proportion of childless women, the percentage of unmatched children, and the replacement level of fertility. I demonstrate the capabilities of ownchild using 2010 Brazilian Census microdata sourced from Integrated Public Use Microdata Series-International to calculate fertility rates by race.
