The Petroleum Administration for Defense Districts (PADD) are geographic aggregations of the 50 states and the District of Columbia into five districts: PADD 1 is the East Coast, PADD 2 the Midwest, PADD 3 the Gulf Coast, PADD 4 the Rocky Mountain region. , and PADD 5 the west coast. Due to its large population, PADD 1 is divided into sub-PADD, with PADD 1A as New England, PADD 1B as the Central Atlantic States, and PADD 1C comprising the Lower Atlantic States. There are two additional PADDs (PADD VI and VII) that encompass the US territories (these are not shown on the map). PADDs help users of EIA petroleum data to assess regional supplies of petroleum products.

During World War II, the Petroleum Administration for War, established by executive order in 1942, used these five districts to ration gasoline. Although the administration was abolished after the war in 1946, Congress passed the Defense Production Act of 1950, which created the Petroleum Administration for Defense and used the same five districts, only now called the petroleum administration for defense districts.

PADDs also allow data users to analyze trends in the movement of crude oil and petroleum products across the country. In 2010 (the last full year for which published data is available), the bulk of petroleum product pipeline movements took place between PADDs 1, 2 and 3 (see table below). More than half of the total inter-PADD product pipeline movements in the United States were from PADD 3 (an area with significant refining capacity) to PADD 1 (a large population center). In contrast, PADD 4 and 5 show very small incoming and outgoing volumes by pipeline, with nothing coming out of PADD 5.

For crude oil, nearly three quarters of inter-PADD pipeline movements in 2010 were movements from PADD 3 to PADD 2 (see table below). These volumes include crude oil produced in the Gulf of Mexico and imports from the Gulf Coast region moving inland to PADD 2 refineries. The volume of crude oil transported by pipeline from PADD 3 PADD 2 has declined steadily in recent years as pipeline receipts of crude oil from the Canadian tar sands and increased production from the Bakken formation in North Dakota have boosted supplies of PADD 2 crude oil. PADD 2 crude supplies reduced their need for Gulf Coast crude oil supplies. The vast majority of inter-PADD pipeline movements occur between PADDs 2, 3 and 4, with very little pipeline activity entering or exiting PADD 1 and 5. Such patterns of crude oil and oil movement. petroleum products would be difficult to understand. discern without the availability of data at the PADD level.
