Figure 1: Examples of residential front yards in 4 cities






Figure 2: Select PRIZM social groups whose neighborhood-level land covers may be compared within and across cities.






Figure 3. Grass, tree, impervious and other land covers (in hectares) pertaining to different PRIZM (social group) Block Groups in Miami.






Figure 4. Landscape pattern (patchiness and shape complexity) of grass/shrub and tree covers pertaining to different PRIZM (social group) Block Groups in Miami. The graphs indicate that the spatial arrangement of land covers varies across different social group/neighborhood types.






Figure 5. The neighborhood/PRIZM group "Old Glories" (a low affluence, high urbanicity group) in Baltimore and Miami maintain similar proportions in the grass, tree/shrub, impervious and other land covers, but they typically have more impervious extents in Miami. Boston's Old Glories Block Groups are different, maintaining much more proportional tree cover (and larger areas of everything), with far greater patch complexity than the other two sites.






Figure 6. Neighborhoods pertaining to the PRIZM group "Young & Rustic" (a low affluence, low urbanicity group) in Baltimore are most different from their counterparts in Boston/Miami, with far smaller areas in all covers (& smaller lots). In Miami, trees dominate (in simple shapes), often with orchards and nurseries on residential parcels in these neighborhoods.
