The committee will review the Contingent Worker Supplement (CWS) of the Current Population Survey, which provides key measures of contingent workers, alternative work arrangements, and insights on the “gig” economy. The committee will review the CWS and other existing data sources, as well as the methodological issues surrounding measurement of these concepts. A workshop to discuss the views of data users, stakeholders, and survey experts will be convened. A report with conclusions and recommendations will be issued to provide guidance for improving the measurement of these aspects of the modern economy, as well as a rapporteur-authored proceedings of the workshop.
