Five decades of CPS wages, methods, and union‐nonunion wage gaps at Unionstats.com
该网站从1973年起提供美国工会、非工会及总体工资的年度数据，并给出基于回归的工会工资差距估计，按人口群体和部门分类，对研究工资不平等和工会影响的学者有用。
Abstract Unionstats.com provides annual measures of union, nonunion, and overall wages, beginning in 1973, compiled from the U.S. Current Population Surveys. Regression‐based union wage gap estimates are presented economy‐wide, for demographic groups, and sectors (private/public, industries). Union wage gaps are higher in the private than in the public sector, higher for men than women, roughly similar for black and white men, and much higher for Hispanic men than for Hispanic women. The database is updated annually.
