Neighborhood effects


In Great American City: Chicago and the Enduring Neighborhood Effect Robert Sampson provides a very different perspective on the “micro-macro” debate. He rejects the methodologies associated both poles of the debate: methodological individualism (“derive important social outcomes from the choices of rational individuals”) and methodological structuralism (“derive important social outcomes from the features of large-scale structures like globalization”). Instead, he argues for the causal importance of a particular kind of “meso” — the neighborhood. He takes the view that neither “bottom-up” or “top-down” sociology will suffice. Instead, we need to look at processes at the level of socially situated individuals.

In this book I proposed an alternative to these two perspectives by offering a unified framework on neighborhood effects, the larger social organization of urban life, and social causality in general…. Contrary to much received wisdom, the evidence presented in this book demands attention to life in the neighborhoods that shape it. (357)

I argue that we need to treat social context as an important unit of analysis in its own right.  This calls for new measurement strategies as well as a theoretical framework that do not treat the neighborhood simply as a “trait” of the individual. (60)

Sampson offers his own instantiation of Coleman’s Boat to illustrate his thinking:

But unlike Coleman (and like the argument I offered in an earlier post about meso-level explanation; link), Sampson allows for the validity of type-4 causal mechanisms, from “neighborhood structure and culture” to “rates of social behavior”. So neighborhoods are not simply outcomes of individual choices and behavior; they are social ensembles that exert their own causal powers.

Sampson offers an articulated methodology for the study of the social life of a city, in the form of ten principles. These include:

  1. Focus on social context
  2. Study contextual variations in their own right
  3. focus on social-interactional, social psychological, organizational, and cultural mechanisms of social life
  4. integrate a life-course focus on neighborhood change
  5. look for processes and mechanisms that explain stability
  6. embed in the study of neighborhood dynamics the role of individual selection decisions
  7. go beyond the local
  8. incorporate macro processes 
  9. pay attention to human concerns with public affairs 
  10. emphasize the integrative theme of theoretically interpretive empirical research while maintaining methodological pluralism (67-68)

The heart of “neighborhood sociology” can be summarized, Sampson asserts, in a few simple themes:

First, there is considerable social inequality between neighborhoods, especially in terms of socioeconomic position and racial/ethnic segregation.  

Second, these factors are connected in that concentrated disadvantage often coincides with the geographic isolation of racial minority and immigrant groups.  

Third, a number of crime- and health-related problems tend to come bundled together at the neighborhood level and are predicted by neighborhood characteristics such as the concentration of poverty, racial isolation, single-parent families, and to a lesser extent rates of residential and housing instability.  

Fourth, a number of social indicators at the upper end of what many would consider progress, such as affluence, computer literacy, and elite occupational attainment, are also clustered geographically. (46)

This set of themes asserts a series of important correlations between neighborhood features and social outcomes. The hard question is to identify the social mechanisms that underlie these correlations. “It is from this idea that in recent decades we have witnessed another turning point in the form of a renewed commitment to uncovering the social processes and mechanisms that account for neighborhood (or concentration) effects. Social mechanisms provide theoretically plausible accounts of how neighborhoods bring about change in a given phenomenon” (46).

This is a fascinating and methodologically innovative piece of urban sociology. Sampson’s use of large data sets to establish some of the intriguing neighborhood patterns he identifies is highly proficient, and his efforts to place his reasoning within a more theoretically sophisticated framework of multi-level social mechanisms is admirable. In an interesting twist, Sampson shows how it is possible to expand on the very costly video-based methodology of the original PHDCN study by making use of Google Street View to do systematic observations of neighborhoods in Chicago and other cities (361).
