There are large numbers of people with no health insurance in the US

Lack of health coverage has been a persistent problem in the U.S. Obama’s Affordable Care Act (ACA) sought to address gaps in the health coverage system and led to historic gains in health insurance coverage by extending Medicaid coverage to many low-income individuals and providing Marketplace subsidies for individuals below 400% of poverty. The number of uninsured nonelderly Americans decreased from over 46.5 million in 2010 (the year the ACA was enacted) to just below 27 million in 2016. However, for the second year in a row, the number of uninsured people increased from 2017 to 2018 by nearly 500,000 people. But although Trump trying to roll back anything associated with the Obamas, the problem was there for a long time before ACA.^[1] Most uninsured people are in low-income families and have at least one worker in the family. Reflecting the more limited availability of public coverage in some states, adults are more likely to be uninsured than children. People of colour are at higher risk of being uninsured than non-Hispanic Whites.^[1] People without insurance coverage have worse access to care than people who are insured. One in five uninsured adults in 2018 went without needed medical care due to cost. Studies repeatedly demonstrate that uninsured people are less likely than those with insurance to receive preventive care and services for major health conditions and chronic diseases.^[1]
