Most & Least Diverse Places in America

The Diversity Index (DI) is a scale of 0 to 100 that represents the likelyhood that two persons, chosen at random from the same area, belong to different race or ethnic groups. If an area’s entire population belongs to one race and one ethnic group, then the area has zero diversity. An area’s diversity index increases to 100 when the population is evenly divided into two or more race/ethnic groups.

When all incorporated cities, towns and census designated places (CDPs) in the  United States are ranked by Diversity Index from highest to lowest using July 1, 2015 estimates, which ones have the highest DI and which ones have the lowest DI?

The top-five MOST diverse locations in the US include:

  1. Lost Hills Census Designated Place in California has a DI of 98.8.
  2. Kennedy Census Designated Place in California had a DI of 97.8.

Measuring Diversity in America: Diversity Index

The Esri Diversity Index expresses the racial and ethnic diversity of a geographic area in a single number that ranges from 0 to 100. The Diversity Index represents the likelihood that two persons, selected at random from a specific geographic area, belong to different race or ethnic groups. If an area’s entire population belongs to one race or ethnic group, then the area has zero diversity. If an area’s population is evenly divided into two or more race/ethnic groups, then the Diversity Index is 100.

The United States had a Diversity Index of 60.6 based on 2010 census counts. As of July 1, 2015, the Diversity Index was estimated to be 63.0 and it is forecast to be 65.3 by July 1, 2020.

When the Unites States are sorted into ranked order by Diversity Index, the top-five states with the highest Diversity Index (DI) (as of July 1, 2015) are:

  • Hawaii, DI = 83.2
  • California, DI = 82.4
  • New Mexico, DI = 77.1
  • Nevada, DI = 75.3
  • Texas, DI = 74.4

From this same ranked order listing of states by DI, the states with the lowest Diversity Index are:

  • Maine, DI = 13.2
  • Vermont, DI = 13.8
  • West Virginia, DI = 15.7
  • New Hampshire, DI = 19.7
  • Montana, DI = 27.1

Note that the Diversity Index is reported for 99,861 locations including cities, towns, villages, counties, boroughs, ZIP Codes and census designated places (CDPs) in the HomeTownLocator series of 50 state gazetteers.
