Mothers’ Social Networks and Socioeconomic Gradients of Isolation
研究印度农村母亲的社会网络，发现富裕和高种姓女性的社交圈反而更小，主要因为她们认识的本群体女性更少，存在强烈的同质性隔离。
Social connections are fundamental to human well-being. We examine the social networks of mothers of young children in rural Odisha, India. Gendered norms around marriage, mobility, and work likely shape this group’s opportunities to form and maintain ties. We track 2, 170 mothers’ networks over 4 years and find a high degree of isolation. Wealthier women and women from more-advantaged castes and tribes have smaller networks than their less-advantaged peers, primarily because they know fewer women within their own socioeconomic group. There exists strong but symmetric homophily by socioeconomic group. Socioeconomic differences are associated with toilet ownership and labor force participation.
