The following report from Brookings Metro proceeds in four sections. First, it discusses how low-wage workers are defined for purposes of this analysis, and briefly describes how it segments that population into smaller groups of individuals likely to face similar labor market prospects. Then, it describes low-wage workers overall, and introduces the nine clusters of low-wage workers with fictionalized examples of people in each group. Third, it examines the variation among low-wage workers by metropolitan area, and how that relates to industrial composition and demographics. The report then conclude with recommendations to support economic mobility for low-wage workers.
