Abstract:
|
We describe ongoing efforts to develop public-use partially-synthetic microdata based on the US Census Bureau's Longitudinal Employer-Household Dynamics (LEHD) database. These are longitudinal linked data on employers and employees, constructed from a variety of administrative and survey data sources. Confidential characteristics of workers, firms, and jobs are replaced with synthetic values. The graph of employment relationships is preserved, to the extent that doing so does not compromise privacy of workers and firms. We describe methods used to generate the synthetic values, and provide a preliminary assessment of utility and disclosure risk in the partially synthetic data.
