Childcare in Transition
Highlights This study uses novel data on multiple childcare types from both kin and nonkin in two culturally similar communities with varying market integration. It tests the hypothesis that market integration is associated with reduced kin support. Who provides support and the type of support vary by level of market integration. Market integration disrupts childcare support from paternal but not maternal kin. Distant kin and nonkin substitute fo…
Religious parents receive more alloparental aid in rural Bangladesh
Researchers have long speculated about the evolutionary benefits of religiosity. One explanation for the evolution of religious ritual is that rituals signal commitment to co-religionists. As a major domain of prosocial behaviour, alloparental care – or care directed at children by non-parents – is a plausible benefit of religious signalling. The religious alloparenting hypothesis posits that parents who signal religious commitment receive greate…
Children's Caregiving and Growth in Northwestern Tanzania
Receiving care from individuals other than one's mother (i.e., allomothering) is a universal aspect of raising children, but whether and how such care impacts children's health remains subject to debate. Existing studies in low‐income societies largely use broad proxies for caregiving behaviors rather than measuring childcare activities, which may mask variation in allomothering and, thus, its impact on children's health. Using data collected to …
Religious women receive more allomaternal support from non-partner kin in two low-fertility countries
Cost structures and socioecological conditions impact the fitness outcomes of human alloparental care in agent-based model simulations
Misperception of peer beliefs reinforces inequitable gender norms among Tanzanian men
Gender role ideology, i.e. beliefs about how genders should behave, is shaped by social learning. Accordingly, if perceptions about the beliefs of others are inaccurate this may impact trajectories of cultural change. Consistent with this premise, recent studies report evidence of a tendency to overestimate peer support for inequitable gender norms, especially among men, and that correcting apparent ‘norm misperception’ promotes transitions to re…
Why marry early? Parental influence, agency and gendered conflict in Tanzanian marriages
Global health interventions increasingly target the abolishment of ‘child marriage’ (marriage under 18 years, hereafter referred to as ‘early marriage’). Guided by human behavioural ecology theory, and drawing on focus groups and in-depth interviews in an urbanising Tanzanian community where female early marriage is normative, we examine the common assumption that it is driven by the interests and coercive actions of parents and/or men. We find l…
The impact of market integration on arranged marriages in Matlab, Bangladesh
Success in marriage markets has lasting impacts on women's wellbeing. By arranging marriages, parents exert financial and social powers to influence spouse characteristics and ensure optimal marriages. While arranging marriages is a major focus of parental investment, marriage decisions are also a source of conflict between parents and daughters in which parents often have more power. The process of market integration may alter parental investmen…
Shared interests or sexual conflict? Spousal age gap, women's wellbeing and fertility in rural Tanzania
He for she? Variation and exaggeration in men's support for women's empowerment in northern Tanzania
Mother's Partnership Status and Allomothering Networks in the United Kingdom and United States
In high-income, low-fertility (HILF) settings, the mother's partner is a key provider of childcare. However, it is not clear how mothers without partners draw on other sources of support to raise children. This paper reports the findings from a survey of 1532 women in the United Kingdom and the United States, in which women described who provided childcare for a focal child and how frequently they did so. We use multivariate Bayesian regression m…
Married Too Young? The Behavioral Ecology of 'Child Marriage
For girls and women, marriage under 18 years is commonplace in many low-income nations today and was culturally widespread historically. Global health campaigns refer to marriage below this threshold as 'child marriage' and increasingly aim for its universal eradication, citing its apparent negative wellbeing consequences. Here, we outline and evaluate four alternative hypotheses for the persistence of early marriage, despite its associations wit…
When marriage is the best available option
Global health studies typically characterise adolescent marriage as a fundamental risk to female wellbeing. In contrast, ethnographic research among communities 'at risk' identifies that early marriage is often viewed as an opportunity weighed against locally feasible alternatives. Addressing this contradiction, we document perceived risks and opportunities of marriage, positioning them among wider concerns facing female adolescents in north-west…
Fathers favour sons, mothers don't discriminate
Parent-offspring conflict unlikely to explain 'child marriage' in northwestern Tanzania
Evaluating the impact of the DREAMS partnership to reduce HIV incidence among adolescent girls and young women in four settings
DREAMS is, to date, the most ambitious effort to scale-up combinations or 'packages' of multi-sectoral interventions for HIV prevention. Evidence of its effectiveness in reducing HIV incidence among AGYW, and demonstrating which aspects of the lives of AGYW were changed, will offer valuable lessons for replication
Father absence but not fosterage predicts food insecurity, relative poverty, and poor child health in northern Tanzania
OBJECTIVES: The importance of fathers in ensuring child health in rural developing populations is questioned by anthropologists and population health scientists. Existing literature focuses on paternal death and child mortality. A relative lack of studies consider alternative forms of father absence and/or more subtle health outcomes. Here we determine the frequency and form of father absence in northern Tanzania, and its relationship to househol…
Support for new mothers and fertility in the United Kingdom
Low fertility across Europe highlights the need to understand reproductive decisions in high-income countries better. Availability of support may be one factor influencing reproductive decisions, though within high-income countries availability varies between environments, including socio-economic environments. We test whether receiving higher levels of support, from different sources (informal and formal) and of different types (practical and em…
Supportive families versus support from families
Support from families can reduce costs of reproduction and may therefore be associated with higher fertility for men and women. Family supportiveness, however, varies both between families â some families are more supportive than others â and within famili
The Reproductive Ecology of Industrial Societies, Part II
Studies of the association between wealth and fertility in industrial populations have a rich history in the evolutionary literature, and they have been used to argue both for and against a behavioral ecological approach to explaining human variability. We consider that there are strong arguments in favor of measuring fertility (and proxies thereof) in industrial populations, not least because of the wide availability of large-scale secondary dat…
Fostering relations
Kinship fostering is generally preferred to non-kin fostering by policy makers in the U.S. and elsewhere. Researchers and policy makers alike tend to provide several proximate reasons for why this may be, generally neglecting an ultimate evolutionary framework. However, kin selection theory predicts that in the absence of genetically related parents, care from kin will result in the most similar life history outcomes. In low-fertility settings, p…
