Examining Neighborhood Diversity Patterns

Population race/ethnic diversity varies widely by neighborhood in the United States. This section reviews use of tools that you can use to examine patterns of neighborhood race/ethnic diversity for anywhere in the United States. There are many types of neighborhood diversity (economic, age, etc.); we examine just one here -- diversity based on race/ethnicity. Using the tools and resources described in this section, you can also examine many other types of neighborhood diversity, or simply sub-county demographic-economic characteristics.

Neighborhood Diversity Index
The diversity index measures the degree of racial and ethnic diversity of the population. The percentage of each race (White, Black, American Indian/Alaska Native, Asian, Native Hawaiian) and Hispanic origin/ethnicity are used to calculate the chance that any two people are from different groups. The index ranges from 0 (no diversity) to 100 (highest diversity). The diversity index is computed for each census tract using data from Census 2010 Summary File 1 Table P5.

Variation in Neighborhood Diversity
Census tract 06001437701 in Alameda County, CA has the highest diversity index (88). Of the approximate 73,000 census tracts, there are more than 800 tracts with a diversity index above 80 (highly diverse). There are more than 8,000 tracts with a diversity index below 10 (little diversity).

Visual Patterns of Neighborhood Diversity
We illustrate use of CV XE GIS with associated GIS project to visually examine patterns of diversity by census tract. We extracted the Census 2010 Table 5 data using the Demographic Economic Data Extraction API tool and then integrated those data into a U.S. by census tract shapefile. See more about the GIS project.

Dallas, TX Area
Diversity Patterns Neighborhood/Census Tract
Census tracts are colored based on value of the diversity index. See color patterns assigned based on diversity index values as shown in legend at left of the map. Blue tracts are most diverse; red tracts are least diverse. Tracts shown with black cross-hatched pattern are tracts with 50-percent or more Hispanic population.

Diversity Patterns by Census Tract
Similar to the Dallas view, but note how different the patterns are. Click on the graphic to see the larger view with more details. In the larger view, the identify tool is used to display a mini-profile for a selected tract. Details about this census tract and mini-profile content are shown in the table below.

Illustrative Table P5 Mini-Profile
Census 2010 Summary File 1 Table P5 items for census tract 51-510-200900 are shown in the table below. Table P5 contains 17 data items for each tract, P0050001 through P0050017. As shown here, the total Census 2010 population of this tract was 4,693. The total non-Hispanic population was 4,534. The relatively low size of the Hispanic population suggests that this tract will have less diversity than others.
