Health insurance premiums in the U.S. significantly increased between 1999 and 2024, outpacing the rate of worker earnings by three times, according to our newly published research in the journal JAMA Network Open.
Premiums can rise if the costs of the medical services they cover increase. Using consumer price indices for the main components of medical care – such as services provided in clinics and hospitals as well as administrative expenses – based on federal data and data from the Kaiser Family Foundation, we found that the cost of hospital services increased the most, while the cost of physician services and prescription drugs rose more slowly.
