Income mixing and segregation Taking a look at the new StatCan D-index and related income mixing metrics At the end of June StatCan released an interesting census tract level metric, dubbed the D-index, measuring how much the income distribution in each census tract differs from the metro-wide distribution, and we decided to take it for a test drive.
