Historically, research on U.S. business activities over time has been hampered by the lack of accurate and comprehensive longitudinal data. To improve this situation, the U.S. Small Business Administration(SBA) contracted with the Bureau of the Census to develop better methods of producing firm size data biginning in 1991. The development of a new longitudinal file with data on establishments and the firms that own them has been a joint project of the Census Bureau and SBA's Office of Advocacy since 1996. This Business Information Tracking Series(BITS), formerly called the Longitudinal Establishment and Enterprise Microdata(LEEM) file, currently consists of data on almost all U.S. establishments with positive payroll for 1989 through 1996. Data for additional years will normally follow at a lag of two years.
This tremendously rich data source opens up numerous possibilities for research on businesses in the U.S. economy. It is first nationwide high-quality longitudinal data base that covers most employer businesses from all sectors of the economy.
