This suggests that as GDP increases, a reduction in the physically and time-intensive tasks of unpaid care work (such as collecting water or fuel) can be observed for (mainly) women, but this does not lead automatically to a more equitable distribution among household members (Ferrant, Pesando and Nowacka, 2014). For a definition of income groups see http://data.worldbank.ore/data-cataIoe/world-deveIoDment-indicators. In Ethiopia, Peru and South Africa time use data is available for girls and boys from age ten, revealing that ten-year-old girls spend on average 44 minutes in unpaid care work compared to 24 minutes for boys of the same age.
