John Casterline, Robert T. Lazarus Professor in Population Studies at OSU, and Laila El-Zeini. Professor of Economics and Political Science at Cairo University, were recently published in Demography. Their study "Multiple Perspectives on Recent Trends in Unwanted Fertility in Low- and Middle-Income Countries" uses data from 78 low- and middle-income countries to examine concurrent trends in unwanted fertility. Results show that unwanted fertility rates—especially the conditional unwanted fertility rate—have declined substantially in recent decades. By contrast, the percentage of births unwanted has declined less, remaining stable or even increasing: from a birth cohort perspective, declines in unwanted fertility have been far more modest than the increased parental success in avoiding unwanted births.
