Yet, globally, time use data remains limited, in particular for developing countries, due to the significant costs and capacities needed to undertake a time use survey. Reporting on SDG Target 5.4 requires regularly collected time-use data disaggregated by sex, age group and location. However, to date, only 83 countries have ever conducted time-use surveys, and only 24% of those were conducted after 2010 (UN Women, 2018). Of the 47 least developed countries, only 8 have collected time-use data.
