This pattern is also confirmed by the OECD Social Institutions and Gender Index (SIGI) Database, which shows that discriminatory social institutions are linked to higher inequality in unpaid work between men and women across the world (OECD, 2014a). By recording workers’ activities throughout the day, these surveys provide a precise estimate of the time devoted to paid work, unpaid work (including housework), leisure and personal care.0 Rather than simply classifying workers on the basis of their main activity (typically obtained from labour force data), these data provide a portrait of how time use is distributed across different activities. As the collection of this type of data is particularly onerous, time-use surveys are not conducted regularly and they are especially rare in emerging economies.
