CRDB is a leader in dynamic business establishment research. We provide transparent data about the economy you can use.


The Business Dynamics Research Consortium has compiled multiple data sets on business and economic activity creating a comprehensive and accessible databank (BDRC Databank) on the US economy, and in the process attract and serve diverse research initiatives across multiple disciplines and academic institutions. Our primary database is NETS (National Establishment Time Series), by Walls and Associates, a truly unique business establishment database.

Walls & Associates NETS database

Coverage of over 55 million unique establishments on a national basis with over 300 data fields, including:

Establishment Data: The NETS Database has over 300 fields that uniquely describe each establishment from 1990 thru 2012. These variables include business type, location information, employment, sales, Dun and Bradstreet ratings and payment performance, and special indicators like minority or women-ownership and whether the establishment imports or exports.

Covers all businesses including sole-proprietors and the self-employed: NETS includes all businesses including from every industry level, and containing the self-employed, sole-proprietors, and partners. No company left behind!

Corporate Affiliation: Headquarters identifiers (HQDuns) are available in every year, as well as an indicator if there has been a headquarters (ownership) change. In addition, the numbers of related establishments or establishments reporting to a headquarters are also computed.

Relocation Behavior: Every significant establishment relocation is chronicled with 30 fields that tell us the move year, SIC, origin and destination, distance of move, employment and sales in the move year, type of location and whether the establishment is still active in the last year. In addition, we have the latitude-longitude of all origins and destinations of all moves.

Kauffman Foundation Brings Out the NETS

The Kauffman Foundation has recently become a national partner with the Business Dynamics Research Consortium (BDRC). In doing so, the Foundation will be able to relicense (at no cost to the approved researchers) the National Establishment Time Series (NETS) Database for research and policy purposes, bringing an important new source of business-level data within reach of many academics focused on understanding business-level outcomes such as revenue and employment trajectories.

BDRC Databank

Building a better economic resource

The cumulative effect of BDRC is to assemble and avail large, simply usable, transparent time-series data sets that are unveiling the reality of the dynamic U.S. economy. Each of these separately assembled data sources can be matched by DUNS number to NETS (National Establishment Time Series) database. Currently deposited into the databank:

NETS: A true business census of the U.S. economy, attempting to locate, verify, and count every establishment (and its jobs and sales) at its unique location anywhere in the U.S., Puerto Rico, or the Virgin Islands.

Preliminary NETS data: Exclusive to BDRC, the lastest preliminary year of the NETS database is used to assemble aggregates, merge with other data, and build applications and websites.

Firm totals: Using the HQDuns affiliation that links each establishment to a parent (including standalone establishments), 3 field variables are created each year for each Headquarters, Branch, or Standalone establishment totaling establishments, jobs, and sales for every establishment in the NETS and BDRC data.

Time-series variables: BDRC assembles new time series variables that can be used with NETS, they are: MSAs, HQFIPS, churn tracking (birth, death, expansion, contraction, and move indicators).

Private capital data: Over 50,000 private equity companies from our partner PitchBook showing equity finance type: 1995-2013.

Public market identification: public market identification including exchange, stock symbol, and IPO date.

Congressional District identification: Congressional District identification for every establishment each year in the time-series from the 113th Congress.
