source Authors’ analysis of data on nursing home residents from the national Minimum Data Set (2006–09). notes Over the three years, nursing homes with no blacks account for 38–39 percent of all the facilities; nursing homes with no whites account for 0.3–0.4 percent of all the facilities. The stratification by quintiles was based on facilities with both whites and blacks. Quintile 1 represents the lowest proportion of blacks; quintile 5, the highest. Each subgroup accounts for approximately 12 percent of all facilities.
