Figure 1. Illustration of Selected Scales of Socioeconomic Context Measurement.

Figure 1

Four scales were considered for measurement of “neighborhood” socioeconomic characteristics. As illustrated here, ZIP codes were the largest area considered, with boundaries that do not necessarily correspond to the census area boundaries. Census tracts were divided into smaller census block groups. One-kilometer airline buffers were by definition circular and of a fixed size, while for other neighborhood definitions the shape and size varied.
