EPA's Report on the Environment (ROE)

Regional and State Trends

The ROE focuses on national-level indicators and also presents indicators at sub-national (e.g., regional and state) scales when sufficient data are available to depict a representative trend. These scales vary widely from very large regions (e.g., eastern versus western U.S.) all the way down to, for a few indicators, data from individual sampling or monitoring sites (e.g., sea level rise at particular tide gauges). Approximately half the ROE indicators present data at sub-national scales, primarily at regional or state scales.

Why does the ROE present trends at sub-national scales?

Sub-national data are important because national-level indicators may mask important variations at sub-national scales. For example, a national-level indicator may show a trend for the nation as a whole, but not whether the trend is increasing in some regions and decreasing in others. State, regional, and other sub-national data, when available, can provide important insights into conditions and trends at these higher degrees of resolution.

How are regional, state, and other sub-national data presented in the ROE?

  • At multiple resolution levels. For 10 indicators, you can use interactive mapping tools to explore the data and zoom to a regional, state, or (in some cases) more local level.
  • By EPA Region. Some indicators present national data broken out by EPA Region. EPA Regions play an important role in the way the Agency's environmental protection efforts are implemented. They follow state borders and do not reflect natural boundaries based on physiography, climate, or biota.
  • By other boundaries. Some indicators present national data broken out by other types of boundaries, including natural boundaries such as ecoregions or watersheds.
  • For particular regions. A few indicators only present data for a particular region, such as an EPA Region or a regional ecosystem of national significance (e.g., Gulf of Mexico, Chesapeake Bay). These indicators are not necessarily representative of similar trends in other regions or in the nation as a whole, and they may or may not scale up to national indicators.

How can I view exhibits with data relevant to a state?

Click on a state in the map below to see a list of indicators. Each listed indicator has one or more exhibits that present sub-national data relevant to that state. To view these exhibits:

  • Click on a listed indicator to go to the indicator page, where you will see all exhibits listed on the left.
  • To view these exhibits and learn which present sub-national data, click on each exhibit. One or more exhibits present sub-national data either:
    • As maps,
    • Broken out by state,
    • Broken out by EPA Region that includes the state, or:
    • Broken out by other types of boundaries (e.g., ecoregions, watersheds, Gulf of Mexico, Chesapeake Bay) that include the state.

For map exhibits, you can also use the table of Interactive Maps to rapidly link to maps where you can zoom to regional, state, and, in some cases, local levels.
