Since the Affordable Care Act (ACA) health insurance marketplaces opened in 2014, there have been a number of changes in insurance participation as companies entered and exited states and also changed their footprint within states. This brief and interactive maps show how insurance participation has changed over time in every county in the U.S.
President Donald Trump and Republicans in Congress pursued several major efforts to repeal and replace the Affordable Care Act (ACA) but were unable to get a bill through the U.S. Senate in 2017. In 2018, Congress did pass a tax bill that eliminated the ACA’s tax penalty for not obtaining health coverage beginning in 2019.
In December 2019, a federal appeals court panel ruled that the law’s individual mandate is unconstitutional since Congress has set the mandate tax penalty to zero and sent the case back to a lower court to determine how much of the rest of the ACA should be invalidated. The case was first brought by a number of Republican state attorneys general, and the Trump administration now argues that nearly all of the ACA should be overturned. The U.S. Supreme Court has now agreed to review the case.

Biden’s plan would, however, increase federal spending, which we do not attempt to estimate here.
