States and Metropolitan Areas
For TRI purposes, “states” includes all U.S. territories. For 2020, facilities located in all 56 states and territories reported to the TRI Program. Texas, Ohio, and California had the most facilities that reported to TRI, and together accounted for 20% of the total number of facilities that reported for 2020.
More than 80% of the United States’ population and many of the industrial and federal facilities that report to the TRI Program are located in urban areas. “Metropolitan Statistical Areas” (MSAs) and “micropolitan statistical areas” in the United States are defined by the Office of Management and Budget (OMB) and consist of one or more socially and economically integrated adjacent counties, cities, or towns.
