Interstate Natural Gas Supply Dependency, 2007
Map: Interstate Natural Gas Supply Dependency

Note: A state’s relative dependence on the interstate natural gas pipeline network for its supplies was determined by the level of natural consumed within the State in 2007 relative to the amount of natural gas produced within the State. A State with no natural gas production was 100 percent dependent on the interstate natural gas pipeline network for its supplies.
