Examining the gender wage gap in logistics

The logistics industry in the United States has faced significant labor shortages for the last couple of decades. Women are a source of labor that has been traditionally underrepresented in the major logistics sectors, transportation, and warehousing. We study the workforce composition and potential gender wage gap across these sectors. Using data from the U.S. Census Bureau from 2003 to 2020, we show that women comprise about 4% of the workforce for truck drivers and 21% for warehouse workers. As traditionally measured by economists, there is a 17% gender wage gap among truck drivers and an 11% wage gap among warehouse workers. A regression analysis suggests that the gap is smaller for warehouse workers, which is consistent with theory that an occupation's stability and predictability can reduce or eliminate wage gaps. Further analysis is carried out on specific occupations within the logistics industry and measures the variation across truck transportation and warehousing industries. There is evidence for a declining gender wage gap across both over time, although the gap remains sizable. This paper provides insight on the trends and status of gender differences in labor outcomes in the logistics industry.
