The inclusion of something as basic as the sex of family farmers in agricultural censuses is vital to ensure the visibility of women's contribution to this work (see Story of Change, "The simple scheme that's driving a quiet revolution for Brazil's family farmers"). There is no global database that brings together national statistics on migration flows to enable a better understanding of migrant family life. These data limitations, in all regions, should be addressed through sustained investment in national statistical systems and in methodological development at global, regional and national levels.
