Gas prices are up across the country, but nowhere are they up as much as in Kingsbury County, S.D., where an average gallon of gas would run you $4.57 a gallon Thursday, 87% more than the price at the start of the Iran war.
How much gas prices have increased depends on where you live, an NBC News analysis of average gas price data from AAA shows. Kingsbury County’s price was up $2.13 a gallon, while Whitley County in Indiana, population 34,000, prices had only increased 73 cents as of Thursday.
It also depends on the state. In Georgia, average gas prices are up $1.18 per gallon, the second-lowest state-level increase in the nation (Georgia suspended its 33 cents per gallon state gas tax in mid-March). But in Illinois, the average price is up $1.84 per gallon, the largest state-level increase in the U.S.
