States and Metropolitan Areas
For 2022, facilities located in all 56 states and territories reported to the TRI Program. Texas, Ohio, and California had the most facilities report to TRI, and together accounted for 20% of the total number of facilities that reported for 2022.
Approximately 80% of the U.S. population and many industrial and federal facilities that report to TRI are in urban areas. The Office of Management and Budget defines Metropolitan Statistical Areas (MSAs) as areas consisting of the county or counties “associated with at least one urban area of at least 50,000 population, plus adjacent counties having a high degree of social and economic integration” as measured through commuting ties. All MSAs are displayed on the “Where You Live” map. The chart below shows TRI chemical releases for 2022 for the 10 most populous MSAs.
