Traditional supports and contemporary disrupters of high fertility desires in sub-Saharan Africa: a scoping review.

RATIONALE

The desired number of children is markedly higher in Sub-Saharan Africa (SSA) than in other major regions. Efforts to understand how and why these desires are generated and maintained have yielded a broad research literature. Yet there is no full picture of the range of contextual, cultural, and economic factors that support and disrupt high fertility desires.

OBJECTIVE

This scoping review synthesizes thirty years of research on the determinants of fertility desires in SSA to better understand what factors underlie men and women's stated fertility desires and how they weigh the costs and benefits of having (more) children.

METHOD

We identified and screened 9863 studies published from 1990 to 2021 from 18 social science, demographic, and health databases. We appraised determinants of fertility desires from 258 studies that met inclusion criteria according to their roles as traditional supports or contemporary disrupters of high fertility desires.

RESULTS

We identified 31 determinants of high fertility desires, which we organized into six overarching themes: economy and costs; marriage; the influence of others; education and status; health and mortality; and demographic predictors. For each theme, we summarize ways in which the determinants both support and disrupt high fertility desires. We find that high fertility remains desirable in many regions of sub-Saharan Africa but contemporary disrupters, such as the economic situations and increases to family planning and education, cause individuals to decrease their desired fertility with such decreases often viewed as a temporary adjustment to temporary conditions. Most included studies were quantitative, cross-sectional, and based on survey data.

CONCLUSION

This review demonstrates how traditionally supportive and contemporary disruptive forces simultaneously influence fertility desires in sub-Saharan Africa. Future studies analyzing fertility desires in sub-Saharan Africa should be informed by the lived experiences of men and women in this region, with qualitative and longitudinal studies prioritized.
