This is the first of a series of Measurement Briefs from the NCAER National Data Innovation Centre based on the findings from the Delhi Metropolitan Area Study. This particular Brief on employment outlines the challenges in measuring women’s work and demonstrates how different approaches of employment measurement determine the status of women’s employment. The results in the Brief suggest the need for caution in interpreting the declining trend of women’s work participation and point to the need for a simpler but comprehensive approach that would better capture activities omitted in traditional labour force surveys
