Racial isolation values based on the 2000 census block group level using the 2010 census boundaries

These data contain a residential isolation value for non-Hispanic blacks (NHB) and non-Hispanic whites (NHW) at the census block group level. Population counts from the 2000 census using the 2010 census boundaries are used to calculate the index. For each block group, the index is the proportion of the population (NHB or NHW) in the index block group and block groups adjacent to the index block group. Islands (areal units with no first-level adjacent areal units) are removed as it is not possible to calculate isolation for units with no adjacent block groups.
