Examining Diversity by State 2015

.. states with the highest race/origin diversity in 2015 were Hawaii, California and New Mexico. States with the lowest diversity were West Virginia, Maine and Vermont. Higher levels of diversity tend to provide a better framework for understanding, tolerance and cooperative developments and progress. Use the interactive table to view, rank, compare states on the diversity index, percent population by race/origin and population by race/origin.

What is the chance that the next person I meet will be different from me, in terms of race origin? The Diversity Index is a number on a scale from 0 to 100 that shows the chance that two people chosen randomly from an area will be different by race and origin. A higher number means more diversity, a lower number, less diversity.

2015 Diversity Patterns by State

See the related section on diversity. USA TODAY used ProximityOne population projections to 2060 by county to examine diversity trends between 2010 and 2060 – a 50-year trend analysis.

This section provides a new estimate of the 2015 diversity index for the U.S. by state based on the latest data. The 2015 population by race/origin estimates are the most recent official Federal U.S. by state data (updated annually). See more about these estimates; access individual state profiles. In addition, the computational methodology is summarized. The U.S. by state demographics dataset is provided as a part of the U.S. State Diversity GIS project. Analyze alternative computations and views of the diversity index.

Examining the 2015 Diversity Index & Race/Origin by State
Some illustrative examples of the interactive table to view … click the Diversity Index column header cell in the table to sort states in ascending order on the Diversity Index. Click that column header cell again to sort states/rows in descending order on the Diversity Index. Find state(s) of interest; see what peer group those states are in based on demographic measures of interest.

Double-click the %Hispanic column header cell in the table to see that New Mexico has the highest %Hispanic population. Click the “population columns only” button below the table, navigate to far right and double-click the Hispanic column header cell to see that California has the largest Hispanic population.

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.

Dallas, TX Area Diversity Patterns by 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.

Relating Visual to Tabular Data
The graphic below shows diversity patterns by census tract in the Alexandria, VA area. The view of Alexandria shows census tracts with black boundary and labeled with the diversity index.

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.
