Fertility in Africa remains the highest in the world, the average total fertility rate for the continent is about 6.3 children per woman. So far little evidence is found of the beginning of a sustained and irreversible fertility decline in sub-Saharan Africa (SSA) of the sort experienced in other developing areas. Contraceptive use is low (except for spacing purposes and outside of marriage) in sub-Saharan Africa, but there is little evidence that this is due to short supply. Reported ideal family sizes remain quite high suggesting that demand for contraception is low. Analysis of the determinants of fertility in Africa using recently available data is likely to provide new insight into the prospects for fertility decline and the design of population policy. Future analysis should focus on four questions that may be answerable using existing data, and may prove useful in evaluating policy and targeting resources : 1) what are the sources and determinants of observed fertility decline in Africa?; 2) what effects does education have on fertility, family size, and contraceptive use?; 3) what are the likely effects of increases in availability and costs of schooling, health care and family planning services on contraceptive use and fertility? and 4) how will these increases affect measures of child survival, educational attainment and anthropometric status?

Fertility rates and population growth influence economic development. The marked declines in fertility seen in some developing nations have been accompanied by slowing population growth, which in turn provided a window of opportunity for rapid economic growth. For many sub-Saharan African nations, this window has not yet opened because fertility rates have not declined as rapidly there as elsewhere. Fertility rates in many sub-Saharan African countries are high: the total rate for the region is estimated to be 5.1 births per woman, and rates that had begun to decline in many countries in the region have stalled. High rates of fertility in these countries are likely to contribute to continued rapid population growth: the United Nations projects that the region's population will increase by 1.2 billion by 2050, the highest growth among the regions for which there are projections. In June 2015, the Committee on Population organized a workshop to explore fertility trends and the factors that have influenced them. The workshop committee was asked to explore history and trends related to fertility, proximate determinants and other influences, the status and impact of family planning programs, and prospects for further reducing fertility rates. This study will help donors, researchers, and policy makers better understand the factors that may explain the slow pace of fertility decline in this region, and develop methods to improve family planning in sub-Saharan Africa.

This overview includes chapters on child mortality, adult mortality, fertility, proximate determinants, marriage, internal migration, international migration, and the demographic impact of AIDS.

This volume, the last in the series Population Dynamics of Sub-Saharan Africa, examines key demographic changes in Senegal over the past several decades. It analyzes the changes in fertility and their causes, with comparisons to other sub-Saharan countries. It also analyzes the causes and patterns of declines in mortality, focusing particularly on rural and urban differences.
