Notes:               The Racial Dissimilarity Index measures the percentage of the
                     non-hispanic white population in a county which would have to change
                     Census tracts to equalize the racial distribution between white and
                     non-white population groups across all tracts in the county.
                     
                     Starting with the 2016 observations, the calculation has been changed
                     so that counties with only one census tract have missing data. Zero
                     values represent counties where the proportions of non-white
                     population and non-hispanic white population are the same. Multiyear
                     estimates from the American Community Survey (ACS) are "period"
                     estimates derived from a data sample collected over a period of time,
                     as opposed to "point-in-time" estimates such as those from past
                     decennial censuses. ACS 5-year estimate includes data collected over a
                     60-month period. The date of the data is the end of the 5-year period.
                     For example, a value dated 2014 represents data from 2010 to 2014.
                     However, they do not describe any specific day, month, or year within
                     that time period.
                     
                     Multiyear estimates require some considerations that single-year
                     estimates do not. For example, multiyear estimates released in
                     consecutive years consist mostly of overlapping years and shared data.
                     The 2010–2014 ACS 5-year estimates share sample data from 2011
                     through 2014 with the 2011–2015 ACS 5-year estimates. Because of
                     this overlap, users should use extreme caution in making comparisons
                     with consecutive years of multiyear estimates.
