Longitudinal Employer-Household Dynamics (LEHD)
Characteristics: Linked employer-employee/household data from multiple sources; available from 1990-2008 (quarterly), but availability varies by state.
Identifiers: person, establishment, firm, industry, geographic (six-digit latitude & longitude)
Longitudinal Business Database (LBD)
Characteristics: The LBD tracks establishments over time (1976-2010, annually), including information on payroll, employment, and establishment entry and exit. The focus is on business dynamics.
Identifiers: establishment, firm, industry, geographic
Longitudinal Research Database (LRD)
Characteristics: The LRD is essentially a combination of the quinquennial Economic Census of Manufacturers (CMF) and (in the non-CMF years) the Annual Survey of Manufacturers (ASM). The value added by the LRD is the ability to track an individual establishment (plant) over time across survey years.
Identifiers: plant, firm, industry, geographic
