Fertility preferences are important measures for forecasting fertility, calculating levels of unwanted or mistimed fertility and assessing unmet need for contraceptives. One of the assumptions underlying the use of fertility preferences for these objectives is that they are relatively stable over time.1 However, in Sub-Saharan Africa-where fertility, both desired and actual, remains comparatively high and childbearing patterns are increasingly heterogeneousfertility preferences are likely to be unstable.* Very little research has focused on how individuals' fertility timing desires change over time; however, there is evidence that other fertility preferences respond to changes in life circumstances. 2,3 Indeed, researchers in the region have argued that even individuals who are committed to a particular family size may temporarily alter their fertility preferences in response to changes in economic or reproductive circumstances. 2,3 In studies from Africa, fertility preferences reported in surveys are often tentative and malleable.
2-6Such flexibility may allow for change in fertility preferences, even over short time periods. Understanding how fertility timing preferences change over time is particularly useful, because the timing of births is likely to influence ultimate family size, perhaps even more so than individuals' ideal number of children. In fertility transition research, which has traditionally focused on aggregate measures of fertility preferences and their predictors, structural changes, such as economic development and societal improvements in education and health, are associated with changes in country-level fertility preferences.7-12 However, fertility preferences are characteristics of individuals and couples, not countries. Rarely have studies, particularly in Sub-Saharan Africa, examined how changes in life circumstances relate to an individual's fertility preferences. The present study uses five waves of longitudinal data collected in rural Malawi in 2009-2010 to examine the stability of women's fertility preferences over time and the life events that are associated with delays or accelerations in the desired timing of the next birth.
Charting Preferences over TimeFertility is highly valued in Sub-Saharan Africa, and the desire to stop childbearing is rare among younger women. Still, a woman may be reasonably certain that she wants to have another child, but she may be less sure about when she wants to have a child; equally, she may be more focused on whether now is the right time to have a child with a particular partner than on precisely how many children she plans to have over her lifetime.

Stability and Change in Fertility Preferences Among Young Women in Malawi*The existence of heterogeneous childbearing patterns in the midst of high fertility suggests that social norms regarding fertility are in flux. Thus, women in such a context may have more flexibility in terms of the desired number or timing of future children. Additionally, women may face few...
