Twelve NaNDA datasets derived from the National Establishment Time-Series (NETS) have been updated to extend coverage from 1990 through 2022. The updated datasets span a wide range of neighborhood business and service categories:

• Dollar Stores
• Law Enforcement
• Civic, Social and Religious Organizations
• Social Services
• Health Care
• Retail Stores
• Recreation
• Grocery Stores
• Eating and Drinking Establishments
• Personal Care and Laundry
• Post Offices and Banks
• Training and Vocation Schools

These datasets provide longitudinal, neighborhood-level data at both the census tract and ZCTA level, enabling researchers to track changes in the built environment — including shifts that occurred during and after the COVID-19 pandemic. Each dataset is available as a free download via ICPSR. To access, visit the NaNDA repository on ICPSR and search the dataset name.
