NETS database by Walls & Associates |
||
|---|---|---|
| To develop a database that better described the dynamics of the U.S. economy, Walls & Associates
teamed up with Dun and Bradstreet (D&B) to convert their archival establishment data into a timeseries
database of establishment information, the National Establishment Time-Series (NETS)
Database.
The NETS Database is constructed from 20 “snapshots” taken every January since 1990 of all active Dun and Bradstreet establishments (currently over 24 million). That data is then put through rigorous quality control, statistical analysis, and additional estimation procedures to create the resulting time-series in the NETS Database. These snapshots use the Duns Marketing Information (DMI) file to determine which establishments were active. Other archival files (e.g., the Credit Rating file) were utilized to provide annual raw establishment data that allowed us to create time-series information.

Each Summer the NETS
Database is updated with another year of establishment information. No establishments are ever
deleted from the Database; but their “LastYear" is indicated, so one can explore the dynamics of
“births” and “deaths” of establishments. Walls & Associates maintains the NETS Database and
continues to update and improve estimates before the next annual update.
Walls & Associates uses
the NETS Database in the conduct of its own consulting business and licenses the Database to other
researchers and analysts.
