Abstract

Neighborhood is a term that, though part of the common vernacular, has varied and sometimes-conflicting definitions (Sampson et al. 2002; Talen 1999). Neighborhoods are commonly understood to be defined spatial units within a city, but as is discussed in other chapters within this volume, neighborhoods are social constructs for which definitions in physical space vary among inhabitants and observers. The research relating to neighborhoods described in this book was conducted with two related objectives: (1) understanding the social interaction and transfer of knowledge relating to health outcomes within neighborhoods and (2) delineation of spatial units for which health, socio-economic, and environmental data can be summarized to support statistical analyses. The research described in this chapter relates to the second of these two objectives and, therefore, considers a ‘neighborhood’ to be a definable spatial unit that may or may not contain residents who share a common identity or behaviors. Specifically, it seeks to test the feasibility of defining spatial units (i.e., neighborhoods) of relatively homogeneous health outcomes and, as a proxy, socio-economic conditions from satellite image data. This objective was achieved by assessing (1) methods for the delineation of neighborhoods from satellite image data and (2) the relationship between satellite remote sensing derived land surface properties and factors affecting health outcomes.
