OUR DATABASES

The Institute for Exceptional Growth Companies has compiled multiple data sets on business and economic activity creating a comprehensive and accessible databank (IEGC 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.

NETS database by Walls & Associates

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 to 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.

IEGC Databank

Building a better economic resource

The cumulative effect of IEGC 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.

Current quarterly data: IEGC assembled and verified D&B DMI files for latest full calendar year rolling thru each quarter. To produce and verify the current year dataset, IEGC goes back through the NETS data to verify and update any information where the current data requires changes.

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 IEGC data.

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

Alternative linkages: D&B DMI files identifying operational categories (eg. franchise, co-op, dealer, health, partnership) starting in 2013.

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.
