In 2023, *** 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 Obamacare The 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 income Although 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 ** percent between 2013 and 2015.

Individuals can now enroll in ACA Marketplace and be eligible for premium tax credits, they may have become newly-eligible for Medicaid in states that have expanded Medicaid, or were previously eligible but didn't know or were unable to apply. Moreover, some states have introduced the Basic Health Program to provide continuous coverage for low-income individuals whose income fluctuates above and below Medicaid eligibility.

White Americans had a below-average rate of just *** percent, whereas *** percent of Black Americans had no health insurance.Impact of the Affordable Care ActThe Affordable Care Act (ACA), also known as Obamacare, was enacted in March 2010, which expanded the Medicaid program, made affordable health insurance available to more people and aimed to lower health care costs by supporting innovative medical care delivery methods. Though it was enacted in 2010, the full effects of it weren’t seen until 2013, when government-run insurance marketplaces such as HealthCare.gov were opened. The number of Americans without health insurance fell significantly between 2010 and 2015, but began to rise again after 2016. What caused the change?The Tax Cuts and Jobs Act of 2017 has played a role in decreasing the number of Americans with health insurance, because the individual mandate was repealed. The aim of the individual mandate (part of the ACA) was to ensure that all Americans had health coverage and thus spread the costs over the young, old, sick and healthy by imposing a large tax fine on those without coverage.

As of March 2023, 62 percent of the respondents had a favorable opinion on the health reform, the Affordable Care Act (ACA) otherwise know as Obamacare, highest share in the provided time interval. Opinions about the ACA

Favorability for the health reform law in the United States has fluctuated since 2010 till 2017. In April 2010, 46 percent of U.S. adults had a favorable opinion regarding the ACA, while 45 percent said the same six years later in October 2016. As expected, Republicans tended to consider the ACA as unfavorable while Democrats were more likely to favor the bill. However, after 2017 the share of U.S. who favor the ACA has steadily increased and is steadily above those who view it unfavorably.

The ACA had a major goal, to expand health care coverage. This bill prevents health plans from limiting or denying coverage to children with pre-existing conditions, arbitrarily withdrawing insurance coverage, and implementing lifetime limits on coverage. The ACA is expected to reduce the number of uninsured individuals by 25 million people by 2023. Those who view the ACA favorably usually reason that the bill will increase health care and insurance access, while the opposition often mentions that the health costs may increase and that the law is too expensive.

As of 2016, the projected number of people that would become uninsured would increase dramatically if President Trump were to recall or replace the Affordable Care Act (also called Obamacare). Should President Trump repeal the Affordable Care Act without a replacement, it is estimated that the number of U.S. residents that would become uninsured would increase from 27 million to 49 million.

U.S. health insurance

The U.S. health insurance system is considered a hybrid system of private funding, private business funding and some government funding for individual health coverage. There is currently no universal health insurance system for U.S. residents. The leading health insurance company in the U.S. as of 2017, by direct premiums written was UnitedHealth Group Inc., followed by Anthem Inc. Revenues generated by life and health insurance companies have more or less stagnated in recent history.

The Affordable Care Act

The Affordable Care Act was enacted in 2010 with the goals of making affordable health insurance available to more people and to expand Medicaid coverage in the U.S. Since 2010 the number of U.S. residents under the age of 65 without health insurance has dropped dramatically. Recent data also indicates that Medicaid enrollment has increased in recent years. It is estimated that repealing the Affordable Care Act in the United States could result in the approximately 26.5 thousand excess deaths per year.

This statistic shows the results of a survey conducted in the United States in February 2017. U.S. adults were asked how health coverage has developed for most US citizens since the implementation of the Affordable Care Act. In total, only seventeen percent of respondents stated that it has improved a lot.

In 2023, the total health expenditure in South Korea accounted for approximately 8.47 percent of South Korea's Gross Domestic Product (GDP). This was a slight decrease from the previous year's share. Overall, this share indicates that as the GDP grew, health spending grew at an even faster rate. Korea's GDP per capita was estimated to have dropped to around 32.3 thousand U.S. dollars in 2022, an increase from around 19 thousand dollars in 2009. Meanwhile, overall medical expenditure in 2021 increased by around 7.5 percent compared to the previous year, up to around 93.5 trillion South Korean won. Nearly 60 percent of the costs were covered by the government or the public health insurance system. Higher health spending is still insufficient Even though the country has been an OECD member since 1996, health spending as a share of the GDP stayed below the OECD average of 8.8 percent until 2021. Similarly, the government’s health expenses lay at around 60 percent, showing a slight increase from the previous year, but this was still lower than the OECD average of almost 74 percent. The increased expenditure was largely attributed to the introduction of what is dubbed “Moon Jae-In Care”, named after the former Korean president, much like the American Affordable Care Act is colloquially known as “Obamacare”. In short, the government will provide greatly expanded coverage for medical treatments and care, increasing the reimbursement rate of the public health insurance, along with other measures. In addition, the Korean population as a whole is rapidly aging, and more people than before are being hospitalized and receiving examinations. Koreans already see doctors far more frequently than any other OECD nationals. Strains on health spending and insurance The Korean national public health insurance system enjoyed seven years of surplus revenue since 2011 but fell into the red in 2018. As noted above, Moon Jae-In Care and the aging population are largely responsible. The years’ worth of revenue is projected to run out in the coming years. Foreigners who come to Korea as medical tourists make things worse, with an all-time high of over 497 thousand medical tourists visiting Korea in 2019, though this has dropped off since the coronavirus (COVID-19) pandemic began.
