A CGD Policy Paper with Ugonma Nwankwo and Megan O'Donnell. We look at available sources to ask (i) Where is data available on employment and wages allowing for comparisons between women and men, and the public and private sectors? (ii) How do women’s employment, compensation, and seniority compare with men’s in the public and private sectors? (iii) How do gender gaps vary by countries’ income level, education levels, and other factors? What are the policy implications of the data we analyze? (iv) Which countries’ efforts can be modeled by others, and how else can global gender gaps in employment and compensation be narrowed? We suggest the Open Government Partnership as a promising platform through which governments can commit to increased transparency around disaggregated employment and wage data, in turn improving policy decision-making aimed at closing gender gaps (or those rooted in other forms of inequality and discrimination).
