This article reviews research on the effects of economic recessions on fertility in the developed world. We study how economic downturns, as measured by various indicators, especially by declining GDP levels, falling consumer confidence, and rising unemployment, were found to affect fertility. We also discuss particular mechanisms through which the recession may have influenced fertility behavi...

Using detailed data on period and cohort fertility in four European countries, this paper discusses various indicators of period fertility, including indicators adjusted for changes in fertility timing.

This study presents trends and patterns of fertility observed in a rural South African population. Various demographic and statistical techniques were used to examine fertility patterns in a population of 21,847 women in a rural KwaZul...

The rapid population growth of many African cities has important implications for population health, yet little is known about factors contributing to increasing population, such as the fertility of internal migrants. We examine whether in-migrants to Kinshasa have different fertility patterns than lifetime Kinshasa residents, and identify characteristics of migrants that may explain difference...

The Fertility Effect of Catastrophe: U.S. Hurricane Births For years, anecdotal evidence has suggested increased fertility rates resulting from catastrophic events in an area. In this paper, we measure this fertility effect using storm advisory data and fertility data for the Atlantic and Gulf Coast counties of the United States. We find that low-severity storm advisories are associated with a ...

Fertility impairments among men treated during childhood for cancer are known to occur after some, but not all, types of anti-cancer therapy. This is the first study to evaluate proven fertility among adult male survivors of childhood acute lymphoblastic leukemia (ALL). In a retrospective cohort study, proven fertility (ever fathered a pregnancy) was evaluated by self-report among 213 men treat...

The 1970s worries of the "population bomb" were replaced in the 1990s with concerns of population aging driven by falling birth rates. Across the developed world, the nearly universallyused fertility indicator, the period total fertility rate, fell well below two children per woman. However, declines in period fertility have largely been an artifact of later – but not necessarily less – childbe...

By taking into account land use and labor characteristics at the household and community levels in addition to individual level factors related to diffusion, gender equity, and socio-demographics the research aims to enhance and update the traditional applicat...

Given the fertility decline in Japan and the importance of fertility knowledge, we conducted an online survey to examine fertility knowledge and the related factors for effective public education. METHODS We studied people aged 18-59 years old, n = 4,328 (the "Gen...

Much of Africa has yet to go through a demographic transition; this Malthusian crisis of high mortality, high fertility, rapid population growth and chronic extreme poverty has been attributed to factors including the status of women, pro-natalist policies, and poverty itself. Large uncertainty exists among demographers as to the relative importance of these factors, mostly since econometric es...
