PADD regions explained: why EIA reports fuel prices by region
The five Petroleum Administration for Defense Districts date back to World War II and still shape U.S. fuel data.
EIA reports weekly fuel prices for the nation, five regions and several sub-regions. The regions are the Petroleum Administration for Defense Districts (PADDs), drawn during World War II to organize fuel supply.
| PADD | Region | States |
|---|---|---|
| 1A | New England | CT, ME, MA, NH, RI, VT |
| 1B | Central Atlantic | DE, DC, MD, NJ, NY, PA |
| 1C | Lower Atlantic | FL, GA, NC, SC, VA, WV |
| 2 | Midwest | IL, IN, IA, KS, KY, MI, MN, MO, NE, ND, SD, OH, OK, TN, WI |
| 3 | Gulf Coast | AL, AR, LA, MS, NM, TX |
| 4 | Rocky Mountain | CO, ID, MT, UT, WY |
| 5 | West Coast | AK, AZ, CA, HI, NV, OR, WA (California is also reported on its own) |
Each region has its own refineries, pipelines and fuel rules, so prices move together inside a region more than across regions. That is why a state page on this site shows its region's weekly average when EIA does not survey the state itself; we label which one you are looking at. See all regions or states.
