About NETS Data


The 2020 National Establishment Time-Series High Technology Database© (NETS-HiTech) is a historical database that provides time-series information on establishment sales growth performance, job creation and destruction, changes in primary markets, merger and acquisitions, mobility patterns, and historical D&B ratings.

It contains annual time-series of information for over 6.8 million U.S. high technology establishments from January 1990 to January 2020 as defined using the detailed 8-digit SIC classification system (over 18,500 industries).
