LBDLongitudinal Business Database
DescriptionThe Longitudinal Business Database (LBD) is a research dataset constructed at the Center for Economic Studies (CES). Currently, the LBD contains the universe of all U.S. business establishments with paid employees from 1976 to 1999. The LBD is updated annually - the next update scheduled for late 2006 will add data through 2004 . The LBD offers researchers at CES and its affiliated Research Data Centers (RDCs) a number of features not available in other longitudinal datasets. These include: Long Time Series - The LBD contains complete establishment histories from 1975 to 2005. Precise birth and death year information are available for most establishments. Industrial Scope - The LBD contains all employer establishments that are in scope for the Economic Census (i.e., all manufacturing, mining, construction, retail, wholesale, service, TCU and FIRE establishments) as well as a large number of public administration and other out of scope entities. Improved Longitudinal linkages - In contructing the LBD, great care was taken to provide researchers with the most complete and accurate set of longitudinal establishment linkages possible. This substantially reduces the number spurious establishment births and deaths observed in the data. In addition, the LBD provides researchers with detailed flags that describe, for each establishment, the nature of the linkages over each year an establishment is observed in the data. Basic establishment demographic data - The LBD contains basic information on establishment size, industry, location and ownership that permit researchers to analyze establishment demographics. Linkages to other micro data - The research capabilities of the LBD can be greatly and easily enhanced by linking it to other establishment and firm information contained in Economic Census and survey files available at CES and the RDCs. More detailed information about the LBD is available in Jarmin and Miranda (CES-WP-2002-17).ObservationsThe LBD covers almost 24 million unique establishments from 1975 to present.Coverage
