What is it about?
This research explores how various family structures—like single-parent families, step-parent families, and polygynous marriages—impact children's survival, growth, and education in a rural Tanzanian community. Using 20 years of data from over 3,000 children belonging to an indigenous Tanzanian community, the study challenges the common belief that nonnuclear family setups are inherently harmful.

Why is it important?
Much of the research on family structure focuses on urban, Western contexts, often overlooking the experiences of rural, marginalized, or indigenous populations. Our study addresses that gap, showing that nonnuclear families in rural Tanzania do not consistently harm children's outcomes. Women in these communities may be resilient, being supported by cultural norms that allow them to change partners when necessary. Such flexibility may reflect strategic decisions to secure sufficient care and resources for their children. Overall, our findings challenge global assumptions about "ideal" family structures and emphasize the value of studying behaviors and collecting rigorous data in diverse cultural contexts.
Perspectives
This article presents valuable, historical data from a marginalised community in Tanzania. This type of data is precious and was therefore a pleasure, and privilege, to work with. Doing the lit-review for this paper made me realise just how imbalanced the work on family structure and child well-being is: Western, educated, or industrialised communities seem to be highly over-represented. Designing the statistical tools and presenting the results was fun---I hope the results are easy to understand, despite the complicated methods!
