Why do some people enjoy larger, more supportive, or otherwise more useful networks than others? Exploring the experiences of New York City mothers whose children were enrolled in childcare centers, Mario Luis Small examines why a great deal of these mothers dramatically expanded both the size and usefulness of their personal networks.

"Child care centers are not just about caring for children. Rather, under the right circumstances, they also foster invaluable community ties among moms. That was a crucial fact about the first kindergartens a century ago, and it is the central lesson of Mario Small's important new book. Unanticipated Gains has important implications for anyone concerned about how to reweave the fabric of American communities."--Robert Putnam, author of Bowling Alone "In this supreme work, Mario Luis Small does nothing less than transform the way that we understand social capital. With meticulous ethnographic fieldwork and a large body of data, he argues that social capital should no longer be conceptualized as individual action divorced from organizational context. To say that this multi-method case study is necessary reading alongside Coleman, Bourdieu, and Wilson is an understatement. Unanticipated Gains provides enormous leverage in explaining social inequality. Small provides a bold new agenda for sociology."--Mitchell Duneier, Professor of Sociology, Princeton University "Unanticipated Gains is a major contribution to the growing literature on social capital. Mario Small's original model of how social capital is influenced by organizational conditions is brilliantly applied to a case study of the experiences of mothers whose children were enrolled in child-care centers in New York. In the process he uncovered mechanisms that produce and perpetuate inequality in personal networks, and thereby provides direction for future research. Indeed, his notion of the 'organizational isolate' will become a key concept in future studies of formal organizations."--William Julius Wilson, University Professor and Director of Joblessness and Urban Poverty Research Program, Harvard University "In Unanticipated Gains, Small suggests an entirely new way to think about our social relationships, situating them within the organizations that we work for, join, and patronize. Small keenly uncovers how these organizations set the parameters of our social worlds, and with an impressive variety of data, he shows that differences in organizations' brokering power is an overlooked source of inequality. This is a supremely smart book that makes it impossible to go back to the old ways of studying individuals outside of the groups within which they live their lives."--Mary Pattillo, Professor of Sociology and African-American Studies, Northwestern University "In his compelling new book, Unanticipated Gains, Mario Small joins sociological theory with detailed empirical evidence to show us how childcare centers generate much-needed social capital in low-income communities. I'll never enter a childcare center again without thinking about this book!"--Sara McLanahan, Professor of Sociology and Public Affairs, Princeton University "Mixing focused interviews with observations both quantitative and qualitative, Small identifies in exquisite detail the mechanisms by which the simple acts of everyday life-enrolling a child in day care-enmesh moms in networks of opportunity and obligation, strengthening their social ties with neighbors and others, thereby weaving the dense matrix of the urban landscape. A beautiful and richly conceived study."--Peter Bearman, Professor of the Social Sciences, Columbia University "Essential.... A great contribution to the burgeoning literature on social capital.... Not only does Small raise an interesting and important question, his book is an exemplary combination of quantitative analyses of survey data with ethnographic fieldwork in child-care centers in New York City.... Small has a masterful writing style; it was difficult to put down the book. Not only will this book be widely read by researchers of social capital and social networks, students will welcome it as welll."--Social & Behavioral Sciences
