The diversity index reports the percentage of times two randomly selected people would differ by race/ethnicity. Working with percents expressed as ratios (e.g., 63 percent = 0.63), the index is calculated in three steps: A. Square the percent for each group, B. Sum the squares, and C. Subtract the sum from 1.00. Eight groups were used for the index: 1. White, not Hispanic; 2. Black or African American; 3. American Indian and Alaska Native (AIAN); 4. Asian; 5. Native Hawaiian and Other Pacific Islander (NHOPI); 6. Two or more races, not Hispanic; 7. Some other race, not Hispanic; and 8. Hispanic or Latino. People indicating Hispanic origin who also indicated Black, AIAN, Asian, or NHOPI were counted only in their race group (0.5 percent of the population). They were not included in the Hispanic group.

Difference in diversity:1990 diversity index subtracted from 2000 diversity index by county

Two changes were made before comparing 1990 and 2000 diversity indexes. "Two or more races" and "Some other race" groups weresummed to produce a singlegroup for 2000. "Asian" and "Native Hawaiian and Other Pacific Islander" groups were created for 1990 from detailed race data. These adjusted groupings produced comparable indexes calculated from seven groups for both 1990 and 2000.
