This layer displays information obtained from analysis of the Food and Drug Administration (FDA) Compliance Check Inspections of Tobacco Product Retailers database. This database contains address-level records for each retailer inspection – including decision date, violation type, and tobacco product type – dating back to 2011. These address-level records are geocoded and aggregated to the county level for multi-year periods* based on the inspection result decision date. Percentages are calculated by dividing the number of inspections with violations (any or minor-related) by the total number inspections in a given area and reporting period.

Note: Multi-year periods are used to enable stable comparisons over time, as some counties have no inspections during a single reporting year.
