The interactions between trade and gender are complex and context specific. Therefore, making trade policies more gender-responsive requires sound national statistics. Statistical authorities, however, in most cases lack data and tools for the measurement of gender and trade. This is especially the case for developing countries where women are most vulnerable and statistical capacities less developed. At the signing of the December 2017 Buenos Aires Declaration on Trade and Women’s Economic Empowerment, countries called for the sharing of methods and procedures for the collection of sex-disaggregated data, and the analysis of gender-focused statistics related to trade. The project is a joint effort of UNCTAD, ECA and ECE to develop a coherent approach to measuring the impact of trade on gender equality using official statistics and building on the existing statistical data and capacity of countries. The expected result will be an enhanced capacity of national statistical authorities to collate and disseminate data and statistics for policy makers for more gender-responsive trade policy. In the longer term, the project will enable a more coherent review of progress towards inclusive trade policy and equitable economic development as part of the 2030 Agenda.
