Unpaid work, across the world, is an area that has generally been neglected by economists as well as development actors. Yet the amount of unpaid work done and the manner in which its burden is distributed have important implications for the well-being of individuals and households, as well as for any economys growth and dynamism. This book establishes that there is an urgent need to measure unpaid work and incorporate it in analysing the critical concerns of an economy. As a first step, it focuses on gathering quality statistics and methodologies required to conduct time-use surveys in moving towards integrating unpaid work in policymaking. Assessing various time-use surveys from the global South Asia Pacific, Latin America, and Africa the book moves on to address critical socioeconomic concerns such as poverty alleviation, employment, gender equality, womens empowerment, as also the overall well-being and development of a nation. With in-depth theoretical foundations and empirical analysis, it builds the case for aggregating quality time-use data for sustainable development of the global South.
