The US has the world’s largest economy, but it still has no universal health insurance coverage, and a part of the population remains uninsured. The number of uninsured people has declined in recent years, but it’s still substantial.

The very high cost of healthcare makes it almost impossible for uninsured people to get care, which is a serious problem.

We’ve collected the latest statistics on the uninsured population in the US from multiple sources. Let’s dive right in

Key Findings

  • 27.2 million Americans have no health insurance
  • Younger adults are at much greater risk of being uninsured than the elderly population.
  • The uninsured rate varies by region in the US, from 2.5% in Massachusetts to 18.0% in Texas.
  • The rate of uninsured people is highest among Hispanic Americans.
  • Most households without health insurance make under $25,000 per year.
  • Affordability is cited as the most common reason (69.6%) for being uninsured in the US.
