National Establishment Time Series Datasets
Drexel University
Welcome to the Google Site for the National Establishment Time Series (NETS) datasets for Drexel University.
The NETS datasets includes information on more than 58 million U.S. business establishments for the years 1990-2014. The longitudinal datasets provide an opportunity to characterize changing neighborhood and business environments.
The Retail Environment and CardioVascular Disease (RECVD) study, led by Gina Lovasi, PhD, Associate Professor and Co-Director, the Drexel Urban Health Collaborative in the Dornsife School of Public Health, recently completed the characterization of the annual point-level location and business characteristics including categorization relevant to health. These data are also available aggregated by census tracts (CT) and zip code tabluation areas (ZCTAs) throughout the contiguous United States (using 2010 boundaries).
The aggregated datasets include data on : Retail (National Establishment Time Series), census block geometries , CrimeRisk data (from ESRI) , land cover (using USGS data), rail transit (from CTOD). While each year from 1990-2014 is available for retail, available years vary for other sources.
The NETS data license ended December 2020. The data are no longer available for use.
