Data on women's ownership of assets are sparse, with no comparable data on individual-level asset ownership. This limits understanding on intra-household dynamics of asset ownership, rights, and preferences from a gender perspective. Amid increasing demand for systematically collected sex-disaggregated statistics on asset ownership and control, the absence of standard guidelines and methods has constrained the collection and production of basic data. To fill this methodological gap, ADB, in collaboration with development partners, supports the efforts initiated under the global initiative Evidence and Data for Gender Equality, which aims to standardize methods of data collection for comparable sex-disaggregated data and advocate for mainstreaming gender statistics on entrepreneurship and asset ownership. Documenting pilot surveys from three countries, this report outlines the importance of sex-disaggregated data on asset ownership and entrepreneurship and describes the intricacies and methodological challenges of producing these data through household surveys.
