"While states with the highest populations unsurprisingly tend to use the most gas, the real fuel efficiency picture comes when you examine each state’s fuel consumption per capita. With that factor added, a very different scenario emerges: High-use states like New York actually have low per-capita usage, while states like Alabama, Iowa, Mississippi, Missouri, New Hampshire, and North Dakota — all states with smaller populations and large distances required for drivers — have higher than average consumption, with the highest per capita usage falling on Wyoming." - Christopher Chung

thought it doesn't seem to take into account that many (though not all) of the states with higher per-capita usage are also states with a lot of farming, which just takes more gas. Whether its for equipment or its to get from one side of the farm to the other on a very regular basis. - Rachel Lea Fox
