This paper provides new evidence that family planning programs are associated with a decrease in the share of children and adults living in poverty. Our research design exploits the county roll-out of U.S. family planning programs in the late 1960s and early 1970s and examines their relationship with poverty rates in the short and longer-term in public census data. We find that cohorts born after federal family planning programs began were less likely to live in poverty in childhood and that these same cohorts were less likely to live in poverty as adults.

This paper introduces a model-based approach for measuring heterogeneity in sex preferences using birth history records. The approach identifies the combinations of preferences over the sex and number of children that best explain observed childbearing. Empirical estimates indicate that a majority of parents in Africa, Asia, and the Americas consider the sex of children when making childbearing decisions. Many parents prefer sons and many prefer daughters. Comparisons with reported preferences suggest that survey respondents tend to underreport the degree to which they prefer sons or daughters. Estimates indicate that, although sex preferences are widespread, they have little effect on aggregate fertility levels.

We study the demographic and economic correlates of the 1918 influenza or “Spanish flu” that killed an estimated 6% of South Africa's population. While the pandemic has received some attention in South African historiography and from social scientists in other contexts, little is known about its long‐term impact on the country. Bringing together data from a range of new sources, including population and agricultural censuses, household surveys, and the voters’ rolls, we provide analyses that show, first, the factors that (do and do not) predict flu mortality across South Africa's magisterial districts, and, second, suggest some important consequences of the flu. Our results reveal a large but short‐lived demographic shock, and detectable, if small scale, long‐term economic consequences.

During the apartheid era, all South Africans were formally classified as white, African, colored, or Asian. Starting in 1970, the government directly provided free family planning services to residents of townships and white-owned farms. Relative to African residents of other regions of the country, the share of African women that gave birth in these townships and white-owned farms declined by nearly one-third during the 1970s. Deferral of childbearing into the 1980s partially explains the decline, but lifetime fertility fell by one child per woman.
