Time-use surveys present advantages for capturing detailed information on time spent on all types of productive activities performed in employment and/or in unpaid non-market services, within a short reference period. When all activities are recorded they can provide a solid basis for obtaining information on hours actually worked, as well as on some aspects of working time arrangements, and are best suited to provide good quality measures of absence from work hours. For individuals and the economy as a whole, time-use collection methods give fewer measurement errors for hours actually worked. This is particularly important for some self-employment jobs (often done by women) that risk being omitted from the conventional employment count due to their working hours being considered atypical, irregular, less regulated or interchangeable with activities performed close to home.The use of time-use surveys as the single source for working time statistics may be constrained by their generally non-annual or irregular frequency, small sample size and high response burden and cost of data compilation. They can be important for comparing and assessing the data quality of hours actually worked, improving questionnaires, as well as for adjusting data for certain population groups from other household surveys.
