This report examines the impact of the changing landscape for job skills on gender disparities in the U.S. labor market. The analysis is based on job skills and preparation data from the U.S. Department of Labor's Occupational Information Network (O*NET), specifically Version 23, released August 2018, and Version 5.1, released November 2003. O*NET analysts rate the importance of 35 skills related to job performance in individual occupations. For the purposes of this analysis, the Pew Research Center grouped these into five major families of job skills: social, fundamental, analytical, managerial and mechanical. Occupations were then assigned to one of four skill tiers based on the importance rating of each of the five major skills, ranging from least important to most important. Examples of occupations in which each of the five skills is most important, or is in greatest need, in 2018 are as follows: (1) social skills--sales managers; (2) fundamental skills--lawyers; (3) analytical skills--physicists; (4) managerial skills--chief executives; and (5) mechanical skills--industrial machinery mechanics. Occupational employment and wage data are from the Current Population Survey (CPS).
