Percentage of people in the U.S. without health insurance 1997-2023

In 2023, 7.6 percent of all people in the United States didn't have health insurance. The share of Americans without health insurance saw a steady increase from 2015 to 2019 before starting to decline in 2020 to 2023. Factors like implementation of Medicaid expansion in additional states and growth in private health insurance coverage led to the decline in uninsured population, despite the economic challenges due to the pandemic in 2020. More coverage after ObamacareThe groups who saw the biggest improvement in health insurance coverage after the ACA was enacted were Hispanic and Black Americans. Meanwhile, the share of White Americans without health insurance also fell due to Obamacare, but the drop in that group wasn’t as dramatic as in other ethnic groups. This is primarily due to the fact that the uninsured rate among White Americans was much lower pre-ACA than among any other group, so there was less room for improvement. ACA was especially significant for those with low incomeAlthough the ACA was signed into law in 2010, many of its major provisions didn’t come into force until 2014, which accounts for the sharp drop in Americans without health insurance in 2014. Adults with a family income lower than 200% of Federal Poverty Level (FPL) were especially impacted by the law, as the share of uninsured adults in this income group dropped 14 percent between 2013 and 2015.

于2023年，美国总人口中约有7.6%的人群未享有医疗保险。自2015年至2019年，未参保美国人的比例呈现持续上升的趋势，但自2020年起开始下降，直至2023年。尽管2020年因疫情引发的经济挑战，但得益于更多州实施医疗补助计划的扩展以及私人医疗保险覆盖率的增长，未参保人口数量呈现下降。在奥巴马医改之后，医疗保险覆盖率得到显著提升的群体主要为拉美裔和非洲裔美国人。与此同时，尽管由于奥巴马医改，未参保的白色人种美国人比例也有所下降，但降幅并不如其他种族群体明显。这主要归因于在奥巴马医改实施之前，白色人种美国人的未参保率已相对较低，因此提升空间有限。奥巴马医改对于低收入群体尤为重要。尽管该法案于2010年签署成为法律，但其主要条款直至2014年才开始实施，这也解释了2014年美国未参保人数的急剧下降。特别是家庭收入低于联邦贫困线（FPL）200%的成年人，该法案对他们的影响尤为显著，2013年至2015年间，该收入群体中未参保成年人的比例下降了14%。
