A number of countries do not have sex-disaggregated wage data. How do you estimate sex-disaggregated GNI per capita for these countries?

The global average female to male wage ratio across all sectors is about 0.8 since 2018. This global average is used to estimate the wage ratio for countries with missing sex-disaggregated wage data. We recognize the limitations in assuming that the global average applies to all countries with missing wage data. The International Labour Organization (ILO) is working to improve availability of sex-disaggregated wage statistics.
