How do you get access to healthcare?


Access to these providers can be expensive if you don't have some form of medical insurance. As of the most recent data, the majority of people in the United States have some form of health insurance coverage, which is typically provided by various healthcare providers including private insurance companies, government programs, and employer-sponsored plans. According to data from the U.S. Census Bureau's report on health insurance coverage in the United States for 2021:

  • Approximately 91.7% of the population had health insurance at any point during the year.
  • About 67.5% of the population had private insurance coverage, either through an employer or directly purchased.
  • Government programs like Medicare and Medicaid covered approximately 37.7% of the population. It's important to note that these figures can overlap; for example, someone might have both private insurance and Medicare.

These statistics suggest that a significant majority of the U.S. population is covered by healthcare providers through various types of insurance plans. The healthcare coverage landscape in the U.S. is complex, with many individuals receiving coverage through multiple sources, reflecting the diverse ways in which healthcare is administered across the country:

  1. Private Health Insurance: This includes employer-provided health coverage and private insurance bought on the open market or through the Health Insurance Marketplace established by the Affordable Care Act (ACA). Approximately 67.3% of the U.S. population has private health insurance.
  2. Medicare: This is a federal program providing health coverage if you are 65+ or under 65 and have a disability, no matter your income. Medicare covers about 18% of the population.
  3. Medicaid: This is a state and federal program that provides health coverage if you have a very low income. Medicaid covers about 20% of the population.
  4. Military Health Care: This includes TRICARE and veterans health care programs, covering active-duty military personnel, veterans, and some of their families.
  5. Uninsured: Despite the available programs, about 8.6% of the population, or approximately 28 million people, did not have health insurance at any point during the year as of the latest data.

It's important to note that some individuals may have more than one type of health insurance coverage. For example, it's common for older adults to have both Medicare and some form of private supplemental insurance.

The precise numbers can vary slightly based on the metrics and the specific point in time of the data collection.
