This Health Policy 101 chapter explores the performance of the U.S. health system on a number of cost, outcomes, and quality measures by comparing it with those in similarly large and wealthy OECD nations. It highlights that despite significant spending, Americans have shorter life expectancies and encounter more barriers to health care, influenced by both the health system's structure and broader socioeconomic factors.

Large majorities of voters, particularly Democratic voters, support a federal right to abortion.
This annual survey of employers provides a detailed look at trends in employer-sponsored health coverage, including premiums, worker contributions, cost-sharing provisions, offer rates, and more. This year's report also looks at how employers are approaching coverage of GLP-1 drugs for weight loss, including their concerns about utilization and cost.
This Health Policy 101 chapter explores how health policy in the U.S. is linked to politics, with the direction of policy influenced by who is in power.
