Business Dynamics data are created from the Census Bureau's Statistics of U.S. Businesses (SUSB), an annual series that provides national and subnational data on the distribution of economic statistics by enterprise size and industry. This includes data on contractions and expansions, along with business births and deaths. The SUSB series excludes data on nonemployer businesses, private households, railroads, agricultural production, and most government entities. We have links below that will take you to Excel data tables and technical documentation. These tables are excerpted from the Census Bureau site. Availability of data by industry and enterprise size varies by type of geography. Data starting with the the 2008-2009 period are posted here.
(Below these links we continue with additional introductory information about this data set.)

Enterprises are defined on a national basis and each consists of one or more domestic establishments (physical locations of businesses) under common ownership or control. The classification of data according to enterprise size is a feature that differentiates SUSB products from a more commonly used Census Bureau product, County Business Patterns, where businesses are classified by size of individual establishment.
The database of employers that underlies the SUSB allows the Census Bureau to track employment in individual businesses over time (i.e., two-year periods such as 2008 to 2009) in areas as small as counties. As a result of this tracking effort, the Census Bureau can publish aggregate Business Dynamics data for these time periods, data that delineate the size of expansions and contractions for existing businesses in terms of employment and establishments, the number of establishments that cease to exist (business deaths) and their related employment, and the number of businesses that come into existence (business births). These statistics allow the data user to see more than just the net change in jobs and establishments (the information presented in most other databases) and examine the dynamics of that change -- births, deaths, expansions and contractions.
Moreover, classifications according to size of enterprise allow the data user to see the numbers of establishments and employees in categories based on the size of parent organizations rather than simply the size of individual establishments. This provides for a less ordinary view of an area's economic structure. For example, according to 2008 County Business Patterns (CBP) data for New Mexico, there were just 82 establishments with at least 500 workers in each of the individual establishments. The CBP distribution of employment according to size of establishment shows that those 82 establishments accounted for 89,440 employees. The data indicate that these large business establishments made up just 14% of total New Mexico employment, almost 641,000 employees reported as of mid-March in the CBP database.
On the other hand, 2008 SUSB data (the initial year for the 2008-2009 dynamic statistics) for New Mexico show that there were 7,325 establishments with 286,092 employees in enterprises of at least 500 workers. If "large" is determined by the size of the parent organization rather than just the size of establishment, then the SUSB data indicate that large businesses made up almost 45% of total New Mexico employment, again about 641,000 employees.
