It’s not a question of if gas costs less in your state than it did a year ago. It’s a question of how much less.

The average price for a gallon of regular gas is down year-over-year in all 50 states and the District of Columbia. That’s according to an analysis of fuel prices reported by AAA as of May 23. The full state-by-state list is included below.

“The main reason is the price of crude oil has been lower — about $60 a barrel compared to last year when it was about $80 a barrel,” AAA spokesperson Aixa Diaz said. “This year, OPEC+ has announced production increases, which have increased supply even though demand hasn’t been as robust as in years past.”

According to AAA’s numbers, New Hampshire posted the largest year-over-year decrease with a 17.36-percent reduction. A year ago, New Hampshire residents were paying $3.51 per gallon of regular gas on average. Today, they’re paying about $2.91 a gallon.

On the other end of the spectrum, the state of Washington had the most modest decrease – about 5.5%. A gallon of regular gas in Washington cost $4.60 on average a year ago, compared to $4.40 today.

Washington’s $4.40 figure is the third-highest in the nation, by the way, trailing only California ($4.86) and Hawaii ($4.49). States with the lowest cost per gallon of regular include Mississippi ($2.66), Louisiana ($2.71) and Oklahoma ($2.82).

Nationally, the average cost per gallon was $3.19 as of May 23, according to AAA’s report. That’s down 11.4 percent from last year’s average cost — $3.59.

“Typically, gasoline prices rise as spring progresses and into the summer due to increased demand and refinery maintenance,” said Gerald L. Perrins, Jr., who also tracks the figures with the Bureau of Labor Statistics’ Division of Consumer Prices and Price Indexes. “However, the current decline in oil prices has delayed this seasonal increase.”
