| Occupational structure category | |||
|---|---|---|---|
| I | II | III | |
| *Income inequality index: represents the share of total income that would need to be transferred from those above the mean level of income to those below the mean, and therefore achieve equality in the distribution of income. †Residential class segregation index: represents the percentage of “upper” white collar workers that would need to change their census tract of residence so that all tracts reflect the overall percentage of “upper” white collar workers in the county. County residential class segregation indices are population weighted and combined into an overall residential class segregation index for each occupational structure category (shown). ‡Residential race segregation index: represents the percentage of the black population that would need to change their census tract of residence so that all tracts reflect the overall percentage of black population in the county. County residential race segregation indices are population weighted by the black population and combined into an overall residential race segregation index for each occupational structure category (shown). | |||
