Gender differences in social networks under subsistence changes
– by Juan Du
Quick question: If something went wrong tonight and you needed help fast—someone to watch a child, lend money, give you a ride—who comes to mind first: a friend, your own family, or your partner’s family? And if you asked your partner, would they choose the same side? People sometimes tease that men have an endless supply of “brother dinners”, while women seem to keep a smaller circle—but hold onto it tightly. It’s easy to shrug and say “that’s just gender” or “that’s just culture”. But our new paper suggests those patterns aren’t fixed and there are gendered differences.
Instead of asking whether men and women are “naturally” different, we asked what happens to social relationships when the rules of everyday life change? In particular, what happens when a community shifts from mainly farming and herding toward deeper involvement in markets—more wage work, more trading, more travel, more time pressure?
We understand that relationships are not just “social”. They are how people get labor help, childcare support, information, and backup when things go wrong. But maintaining relationships takes time. And time is the one resource that becomes painfully scarce as market life expands. The basic idea is that not all social ties cost the same to maintain. In our paper, we focus on two types of relationship: friendship and kinship.
You may able to list a few friends in your daily life, but it is hard to say whether you will keep your friends the same during your lifetime. And, as you grow older, you find that maintaining friendships become even more difficult. Thus friendships become incredibly valuable and expensive. You don’t keep friendships strong by accident—you keep them strong by showing up.
Whereas kin ties can work differently. In many rural settings, cooperation among relatives is woven into everyday routines: shared labor work, shared responsibilities, shared obligations, and the kind of long-term accounting that doesn’t reset every time you miss a meal together. That doesn’t mean kin ties are always easy or conflict-free, but they can be harder to “drop” and sometimes more resilient when time is tight.
So when market participation increases, we expected a simple trade-off to intensify: friendship becomes more expensive; kin cooperation may become a safer bet.
And because market work and mobility often change more for men than for women in many settings, we also expected something else: men’s networks might be reshaped more strongly by market involvement, while women’s networks might remain steadier. Not because women are “born stable,” but because women’s daily cooperative demands—childcare, household coordination, local mutual aid—may stay locally focused even as markets expand.
We worked in a Tibetan community in the Shangri-La region of Yunnan, where economic life has been shifting quickly from traditional farming and herding subsistence to more market involved. Our dataset comes from more than a decade of cumulative research across 14 villages. We collected detailed information on 1,169 married adults, focusing on their core social interactions.
We separated these relationships into four types:
- the person’s overall core network
- biological kin
- in-laws (affinal kin)
- friends (non-kin)
And we used a simple structural measure—network density—to capture whether someone’s close ties form a tightly connected cluster or a looser set. Dense networks can be a sign of coordinated support: people know each other, information travels fast, and cooperation can be reinforced through reputation and mutual monitoring.
We found that among men, higher market participation went with a shift away from friends and toward kin. As men became more engaged in market activities, their kin networks became more cohesive, while friend networks became less cohesive.
This is not the same as saying “men lose friends.” What we see looks more like reallocation. When time and movement are squeezed, men appear to concentrate social effort on relationships that are more durable and more predictably cooperative. If showing up frequently becomes hard, friendship—especially the kind built on frequent contact—may be the first thing to thin out.
Women’s networks, looked comparatively stable across market involvement. Women maintained dense, high-quality core ties regardless of whether they were more or less involved in market activities. The most plausible explanation is not that women are “just better at relationships,” but that women’s roles and cooperative needs remain more locally embedded: if you are coordinating childcare, household work, and everyday mutual help, you cannot afford to let your support network drift.
We also looked at post-marital residence—whether people live near their own family or near their spouse’s family affects their relationships. This matters because residence literally determines who is within reach for daily cooperation. And we found that:
- if you live near your natal kin, your biological-kin network is stronger;
- if you live near your spouse’s side, your in-law network becomes stronger.
That might sound obvious, but it implied that in-laws can operate as real cooperative partners, not merely “secondary” ties. When biological kin are less accessible, affinal kin can step in and support a bilateral cooperative network—a support system sustained by both sides of the family rather than only one lineage line.
So yes, you can still recognize the old pattern—men with lots of social occasions, women with steadier core ties. But what matters is how that pattern moves when work starts pulling people around and evenings disappear. In this community, the changes were clear: as time and mobility constraints grew, men and women reorganized which relationships they kept warm, and which ones were allowed to cool.
