Note: Column (1) is 100*[ln(50th percentile wage)−ln(10th percentile wage)]. Similarly column (5) is 100*[ln(90th percentile wage)−ln(50th percentile wage)]. Composition adjustments are made using the Dinardo, Fortin, and Lemieux (1996) kernel reweighting approach. The demographic characteristics controlled for in the composition adjustments are a quartic in age, dummies for region of the country (using the four major census regions), marital status, and race/ethnicity (using mutually exclusive categories of white non-Hispanic, black non-Hispanic, Hispanic any race, and other). The occupations are the 250+ detailed occupations. The base year is 2007, which is further explained in the text.
