The American Health Care Act, the Republican bill to overhaul the US healthcare system, is expected to be voted on by the full House of Representatives later this week.

Experts in health policy have been digesting what the law could change for Americans on average, including the estimated impact on the cost of health insurance by the AHCA, which has also been referred to as “Trumpcare” by lawmakers and outlets on both sides of the aisle, despite the White House’s pushback on the name.

As part of the AHCA, Americans who do not get coverage through their employer or a government program like Medicaid or Medicare would receive a tax credit to buy insurance through the individual insurance market.

The AHCA does not adjust subsidies based on income or cost of living, unlike the Affordable Care Act, the healthcare law better known as Obamacare, instead giving a flat total to people based on their age.

WalletHub looked at tax-credit structures of both the ACA and the AHCA and determined the metro areas where the average tax credit for insurance would fall the most.

The cities are clustered in a few states. Six of the 17 metro areas that would see the average credit decline by $3,500 or more are in North Carolina - the most of any state.

Only two of the top 17 cities are in states that voted for Hillary Clinton, with the other 15 cities in states that went for Donald Trump in November.
