Oil prices are falling, and for many Americans that’s good news, as gas prices at the pump are down and likely will stay that way in the coming months. But for some — especially residents of certain states — the falling oil prices aren’t the best news.

A study released this month by financial site MoneyRates.com , which ranked states based on their rates of oil production, oil consumption and the percentage of oil workers employed in each state’s workforce, found that some states will feel the falling-oil-price burden more heavily than others.

According to Richard Barrington, the senior financial analyst for MoneyRates, while robust oil production is usually good for a state, falling oil prices can hurt high-oil-production-states’ economic performance (not to mention impact the related job market), at the same time that it boosts the economic performance of states that produce little or no oil — in particular those that also consume a lot of it.

Here are the five states most hurt by falling oil prices, according to MoneyRates.com:

1. North Dakota

Oil-rich North Dakota will feel the biggest negative impact from falling oil prices thanks to the fact that oil production has been such a big help to North Dakota’s economy in recent years (the state has the lowest unemployment in the country, in part due to oil-related jobs) — and lowered prices could slow growth. The study reveals that “at 4.61%, the percentage of oil workers in North Dakota’s workforce is the second highest in the nation, and the state produces more than eight times the amount of oil that it consumes … that’s a bad combination in the context of lower oil prices.” MoneyRates estimates that the drop in oil prices over the past year will cost North Dakota $11 billion in 2015 – or roughly $16,000 per resident.

2. Wyoming

Oil jobs are a bigger percentage of the job market in Wyoming than in any other state (they make up more than 6% of the jobs), which is what makes the falling oil prices such a big threat in this sparsely populated state, Barrington says. MoneyRates estimates that the oil-price drop will cost Wyoming $1.38 billion in 2015.

3. Alaska

Alaska — home to the 800-mile-long Trans-Alaska Pipeline System — will feel a major shock from falling oil prices because it is both a big producer of oil and a significant part of its workforce works in the oil industry. The state stands to lose more than $6 billion in 2015 due to falling oil prices, MoneyRates estimates.

4.Oklahoma

While the overall economic impact of falling oil prices on this state ($660 million, or an average of $170 per resident) is small compared with some other states, the big oil price impact here will happen with regards to the job market, as 3.64% of the state’s workforce is employed in the oil industry, explains Barrington.

5. New Mexico

There’s nothing enchanting about what will happen to New Mexico thanks to falling oil prices: This state, which will get hurt in terms of economic impact (it will cost them $2.19 billion in 2015, according to MoneyRates) and jobs, lands in the No. 5 spot on this list.
