Longitudinal Establishment Microdata at the Bureau of Labor Statistics: Development, Uses, and Access

James R. Spletzer


The Bureau of Labor Statistics (BLS) is currently constructing a longitudinal database that will contain quarterly employment and wage data for virtually all business establishments in the United States. This longitudinal database will enable us to track changes in employment and wages not only at the macro level, but also at the micro level of the establishment. This database, referred to as the Longitudinal Database or LDB for short, will be used to generate high quality, high frequency, timely and historically consistent information regarding not only job creation and job destruction, but also the life cycle of establishments. The purpose of this paper is to describe this database and to present some research results that will highlight the uses of this database
