  1. Groups are based on the Tract-level data. N(%) contains the percent of all tracts in the grouping analysis (n = 4177). The fields 2000 and 2013 contain the NME rates (%) of the group centers for those years. CHG contains the absolute change in NME rate (%) from 2000 to 2013. The Line Color field corresponds to the line colors used in Fig. 5 and the Description field contains a short description of the starting NME rate and the change over the study period
