This paper reviews some of the empirical evidence from time use surveys in Sub-Saharan Africa.Starting from a discussion of the 1993 revision of the System of National Accounts (SNA), the paper reviews definitions of work, both market-based and non-market work, paid and unpaid, and how these different types of work are classified and counted within and outside the SNA. The paper then summarizes the results of national time use surveys in four SSA countries, Benin, Madagascar, Mauritius, and South Africa, along with results from the time use module of the Ghana Living Standards Survey, paying particular attention to domestic work, the care economy, and non-economic activity. In conclusion, the paper examines some of the potential correlations between time use patterns and other development variables.
