Figure 6(b) represents a two-level model with each of six neighborhoods having its own poor health/social class relationship. The thick solid lines represent the average poor health rates for the two groups, while the symbol-lines (one for each neighborhood) represent the variation between neighborhoods around the average line. Since the individual relationship between social class and poor health is also shown in the model, the graph implies that the variation between neighborhoods is not due solely to the varying social composition of neighborhoods and is, therefore, contextual. The neighborhood differences, however, are assumed to be simple such that neighborhoods that are high for one group are also high for the other and vice versa (similar to the ‘random-intercepts’ model). Thus, while there is a (contextual) geography of poor health, it can be summarized in one map.
