shows on a scale of 0 to 100 how likely it is two people from an area would have a different race or ethnicity.A score of 0 would mean everyone had
47 41 6t the same race and ethnicity;a score of 100 would mean everyone in an area had a distinctly different combination of race and ethnicity.Nearly
everywhere is some place in the middle The index was invented in 1991 by Phil Meyer of the University of North Carolina and Shawn McIntosh,who
was then with USA TODAY.This score differs from the Census Bureau's version of the diversity index because of differences in how the bureau's
formula counts race and Hispanic origin.
