Racial isolation values based on the 2010 census tract level using the 2013-2017 ACS 5-year population estimates

These data contain a residential isolation value for non-Hispanic blacks (NHB) and non-Hispanic whites (NHW) at the census tract level. Population counts from the 2013-2017 5-year American Community Survey (ACS) 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 tracts.
