Relative Concentration measures the extent to which minorities are concentrated in space, with respect to the average concentration of whites, a relative measure of population density. High numbers indicate that minorities are more concentrated in space than are whites. Values of zero indicate that minority children experience the same population density (i.e. land per person) as whites, positive values indicate that whites experience lower population density than minorities, and negative values indicate that minorities experience lower population density than whites.
Racial groups refer to people who indicated they were of specified race
"alone." Excludes those specifying two or more races. Indices in metro
areas with small numbers of specified racial/ethnic groups should be
used with caution.
