Examining Neighborhood Diversity Patterns
-- Washington, DC Region
Population race/ethnic diversity varies widely by neighborhood 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 the related section, you can also examine many other types of neighborhood diversity, or simply sub-county demographic-economic characteristics.

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.

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.

Using the GIS Resources
The Geographic Information System GIS project/files and software used to develop diversity views shown in this section are available at no fee to members of the ProximityOne User Group. Zoom to you own areas of interest. Change labeling/colors/appearance. Add other geography. Select from other wide-ranging demographic-economic data. Join now; no fees to participate.
Support & DMI Web Sessions
Learn more about using resources described in this section. Join us in a Decision-Making Information Web session. There is no fee for these one-hour Web sessions. Each informal session is focused on a specific topic. The open structure also provides for Q&A and discussion of application issues of interest to participants. We can address your specific questions about tools to visually analyze patterns.
ProximityOne develops geographic-demographic-economic data and analytical tools and helps organizations knit together and use diverse data in a decision-making and analytical framework. We develop custom demographic/economic estimates and projections, develop geographic and geocoded address files, and assist with impact and geospatial analyses. Wide-ranging organizations use our tools (software, data, methodologies) to analyze their own data integrated with other data. Follow ProximityOne on Twitter at www.twitter.com/proximityone. Contact ProximityOne (888-364-7656) with questions about data covered in this section or to discuss custom estimates, projections or analyses for your areas of interest.
