The number of persons without health insurance coverage in the United States is one of the primary concerns raised by advocates of health care reform. A person without health insurance is commonly termed uninsured (regardless of insurance of objects unrelated to health), and this article uses the term in this sense as well.

Multiple surveys indicate the number of uninsured has fallen due to expanded Medicaid eligibility and health insurance exchanges established due to the Patient Protection and Affordable Care Act, also known as PPACA or "Obamacare". These changes took effect January 1, 2014. The Commonwealth Fund reported in July 2014 that an additional 9.5 million people aged 19-64 had obtained health insurance, roughly 5% of the working-aged population.[2] Gallup reported in July 2014 that the uninsured rate among adults 18 and over fell from 18.0% in Q3 2013 to 13.4% by Q2 2014.[3] Rand Corporation had similar findings.[4]

According to the United States Census Bureau, in 2012 there were 48.0 million people in the US (15.4% of the population) who were without health insurance.[5]

The causes of this rate of uninsurance remain a matter of political debate. Rising insurance costs have contributed to a trend in which fewer employers are offering health insurance, and many employers are managing costs by requiring higher employee contributions. Many of the uninsured are the working poor or are unemployed. Others are healthy and choose to go without it. Some have been rejected by insurance companies and are considered "uninsurable". Some are without health insurance only temporarily. Some choose faith-based alternatives to health insurance.

Estimates of the number uninsured[edit]

Gallup estimated in July 2014 that the uninsured rate for adults (persons 18 years of age and over) was 13.4% as of Q2 2014, down from 18.0% in Q3 2013 when the health insurance exchanges created under the Patient Protection and Affordable Care Act (PPACA or "Obamacare") first opened. The uninsured rate fell across nearly all demographic groups.[6]

The Commonwealth Fund reported that the uninsured rate among adults 19-64 declined from 20% in Q3 2013 to 15% in Q2 2014, meaning approximately 9.5 million more adults had health insurance.[7]

The United States Census Bureau annually reports statistics on the uninsured. The 2012 Census Bureau Health Insurance highlights summary report states that:

The Rand Corporation reported that by March 2014: "Enrollment in employer-sponsored insurance plans increased by 8.2 million and Medicaid enrollment increased by 5.9 million, although some individuals did lose coverage during this period. The authors also found that 3.9 million people are now covered through the state and federal marketplaces — the so called insurance exchanges — and less than 1 million people who previously had individual-market insurance became uninsured during the period in question. While the survey cannot tell if this latter group lost their insurance due to cancellation or because they simply felt the cost was too high, the overall number is very small, representing less than 1 percent of people between the ages of 18 and 64."[8]

Uninsured demographic[edit]

Uninsured Americans in 2007, by income status

The Census Bureau reports that in 2007 nearly 37 million of the uninsured were employment-age adults (ages 18 to 64) and more than 27 million worked at least part-time. Approximately 61% of the roughly 45 million uninsured live in households with incomes under $50,000 (13.5 million below $25,000 and 14.5 million at $25,000 to $49,000).[9] And 38% live in households with incomes of $50,000 or more (8.5 million at $50,000 to $74,999 and 9.1 million at $75,000 or more). As stated by the Census Bureau, people of Hispanic origin were the most affected by being uninsured; nearly a third of Hispanics lack health insurance. In 2004, about 33% of Latinos were uninsured as opposed to 10% of white, non-Latinos [10] However, this rate decreased slightly from 2006 to 2007, from 15.3 to 14.8 million, a decrease of 2 percentage points (34.1% to 32.1%). The state with the highest percentage of uninsured was Texas (24.1% average for three years, 2004–2006). New Mexico has the second highest percentage of residents without health insurance at 22%.[11] It has been estimated that nearly one-fifth of the uninsured population is able to afford insurance, almost one quarter is eligible for public coverage, and the remaining 56% need financial assistance (8.9% of all Americans).[12] An estimated 5 million of those without health insurance are considered "uninsurable" because of pre-existing conditions.[13] A recent study concluded that 15% of people shopping online for health insurance are considered "uninsurable" because of a pre-existing condition, or for being overweight. This label does not necessarily mean they can never get health insurance, but that they will not qualify for standard individual coverage. People with similar health status can be covered via employer-provided health insurance, Medicare, or Medicaid.[14]

Uninsured children and young adults[edit]

The current estimate for uninsured children does not greatly differ from past estimates. In 2009 the Census Bureau states that 10.0 percent or 7.5 million children under the age of 18 were medically uninsured. Children living in poverty are 15.1 percent more likely than other children to be uninsured. The lower the income of a household the more likely it is they are uninsured. In 2009, a household with an annual income of 25,000 or less was only 26.6 percent likely not to have medical insurance and those with an annual income of 75,000 or more were only 9.1 percent unlikely to be insured.[15] According to the Census Bureau, in 2007, there were 8.1 million uninsured children in the US. Nearly 8 million young adults (those aged 18–24), were uninsured, representing 28.1% of their population. Young adults make up the largest age segment of the uninsured, are the most likely to be uninsured, and are one of the fastest growing segments of the uninsured population. They often lose coverage under their parents' health insurance policies or public programs when they reach age 19. Others lose coverage when they graduate from college. Many young adults do not have the kind of stable employment that would provide ongoing access to health insurance.[16][17] According to the Congressional Budget Office the plan the way it is now would have to cover unmarried dependents under their parents' insurance up to age 26. These changes also affect large employers, including self-insured firms, so that the firm bears the financial responsibility of providing coverage. The only exception to this is policies that were maintained continuously before the enactment of this legislation. Those policies would be grandfathered in.[2]


Non-citizens are more likely to be uninsured than citizens, with a 43.8% uninsured rate. This is attributable to a higher likelihood of working in a low-wage job that does not offer health benefits, and restrictions on eligibility for public programs. However, most of the uninsured in the US are citizens (78%).[18] The longer a non-citizen immigrant has been in the country, the less likely they are to be uninsured. In 2006, roughly 27% of immigrants entering the country before 1970 were uninsured, compared to 45% of immigrants entering the country in the 1980s and 49% of those entering between 2000 and 2006.

Most uninsured non-citizens are recent immigrants; almost half entered the country between 2000 and 2006, and 36% entered during the 1990s. Foreign-born non-citizens accounted for over 40% of the increase in the uninsured between 1990 and 1998, and over 90% of the increase between 1998 and 2003. One reason for the acceleration after 1998 may be restrictions imposed by the Personal Responsibility and Work Opportunity Reconciliation Act (PRWORA) of 1996. Almost seven out of ten (68%) of uninsured non-citizens live in California, Texas, Florida, or New York.[19]

Downturn effects[edit]

A report by the Kaiser Family Foundation in April 2008 found that US economic downturns place a significant strain on state Medicaid and SCHIP programs. The authors estimated that a 1% increase in the unemployment rate increase Medicaid and SCHIP enrollment by 1 million, and increase the number uninsured by 1.1 million. State spending on Medicaid and SCHIP would increase by $1.4 billion (total spending on these programs would increase by $3.4 billion). This increased spending would occur while state government revenues were declining. During the last downturn, the Jobs and Growth Tax Relief Reconciliation Act of 2003 (JGTRRA) included federal assistance to states, which helped states avoid tightening their Medicaid and SCHIP eligibility rules. The authors conclude that Congress should consider similar relief for the current economic downturn.[20]

Types of insurance[edit]

Americans are accessing their medical insurance through employment-based programs, private health insurance companies, and Medicaid. The Census Bureau reports that in 2010 persons covered by private health insurance decreased to 64 percent. This was not a dramatic decrease from those being covered by private insurance companies in 2009, at 195.9 million, but private health coverage has continued to decline since 2001. Those persons being covered by government sponsored health insurance programs have increased. During 2010 persons insured through government programs increased slightly from 30.6 percent to 93.2 million during 2009 covered 31.0 percent or 95.0 million. Persons covered by employment-based health insurance have also declined. The decrease in employment-based health insurance to 55.3 percent in 2010 from 56.1 percent in 2009. And the trend continued in 2011. According to the Gallup-Healthways Well-Being Index, only 44.6% of Americans got their health insurance from their employer.


The numbers of uninsured Americans and the uninsured rate from 1987 to 2008
The percent of people in US who reported not seeking medical care due to high cost.

Americans who are uninsured may be so because their job does not offer insurance; they are unemployed and cannot pay for insurance; or they may be financially able to buy insurance but consider the cost prohibitive.[citation needed] During 2009 the continued low employment rate has negatively affected those who had previously been enrolled in employment-based insurance policies. Census Bureau states a 55 percent drop. Other uninsured Americans have chosen to join a health care sharing ministry as an alternative to insurance.[21]

Low-income workers are less likely than higher income individuals to be offered coverage by their employer (or by their spouse's employer) and less able to afford buying it on their own. Beginning with wage and price controls during World War II, and cemented by an income tax exemption ruling in 1954, most working Americans have received their health insurance from their employers.[22] However, recent trends have shown an ongoing decline in employer-sponsored health insurance benefits. In 2000, 68% of small companies with 3 to 199 workers offered health benefits. Since that time, that number has continued to drop to 2007, when 59% offered health benefits. For large firms with 200 or more workers, in 2000, 99% of employers offered health benefits; in 2007, that number stayed the same. On average, considering firms of all numbers of employees, in 2000, 69% offered health insurance, and that number has fallen nearly every year since, to 2007, when 60% of employers offered health insurance.[23]

One study published in 2008 found that people of average health are least likely to become uninsured if they have large group health coverage, more likely to become uninsured if they have small group coverage, and most likely to become uninsured if they have individual health insurance. But, "for people in poor or fair health, the chances of losing coverage are much greater for people who had small-group insurance than for those who had individual insurance." The authors attribute these results to the combination in the individual market of high costs and guaranteed renewability of coverage. Individual coverage costs more if it is purchased after a person becomes unhealthy but "provides better protection (compared to group insurance) against high premiums for already individually insured people who become high risk." Healthy individuals are more likely to drop individual coverage than less-expensive, subsidized employment-based coverage, but group coverage leaves them "more vulnerable to dropping or losing any and all coverage than does individual insurance" if they become seriously ill.[24]

Roughly a quarter of the uninsured are eligible for public coverage but are not enrolled.[25][26] Possible reasons include a lack of awareness of the programs or of how to enroll, reluctance due to a perceived stigma associated with public coverage, poor retention of enrollees, and burdensome administrative procedures. In addition, some state programs have enrollment caps.[26]

A study by the Kaiser Family Foundation published in June 2009 found that 45% of low-income adults under age 65 lack health insurance.[27] Almost a third of non-elderly adults are low income, with family incomes below 200% of the federal poverty level.[27] Low-income adults are generally younger, less well educated, and less likely to live in a household with a full-time worker than are higher income adults; these factors contribute to the likelihood of being uninsured.[27] In addition, the chances of being healthy decline with lower income; 19% of adults with incomes below the federal poverty level describe their health as fair or poor.[27]


A study published in the American Journal of Public Health in 2009 found that lack of health insurance is associated with about 45,000 excess preventable deaths per year.[28] One of the authors characterized the results as "now one dies every 12 minutes."[29] Since then, as the number of uninsured has risen from about 46 million in 2009 to 48.6 million in 2012, the number of preventable deaths due to lack of insurance has grown to about 48,000 per year.[30]

A survey released in 2008 found that being uninsured impacts American consumers' health in the following ways:[31]

The costs of treating the uninsured must often be absorbed by providers as charity care, passed on to the insured via cost-shifting and higher health insurance premiums, or paid by taxpayers through higher taxes.[32] On the other hand, the uninsured often subsidize the insured because the uninsured use fewer services[33] and are often billed at a higher rate.[34] A study found that in 2009, uninsured patients presenting in U.S. emergency departments were less likely to be admitted for inpatient care than those with Medicare, Medicaid, or private insurance.[35] 60 Minutes reported, "Hospitals charge uninsured patients two, three, four or more times what an insurance company would pay for the same treatment."[36] On average, per capita health care spending on behalf of the uninsured is a bit more than half that for the insured.[18]

A study published in August 2008 in Health Affairs found that covering all of the uninsured in the US would increase national spending on health care by $122.6 billion, which would represent a 5% increase in health care spending and 0.8% of GDP. “From society’s perspective, covering the uninsured is still a good investment. Failure to act in the near term will only make it more expensive to cover the uninsured in the future, while adding to the amount of lost productivity from not insuring all Americans,” said Professor Jack Hadley, the study’s lead author. The impact on government spending could be higher, depending on the details of the plan used to increase coverage and the extent to which new public coverage crowded out existing private coverage.[37]

Over 60% of personal bankruptcies is caused by medical bills. Most of these persons had medical insurance.[38]

Emergency Medical Treatment and Active Labor Act (EMTALA)[edit]

EMTALA, enacted by the federal government in 1986, requires that hospital emergency departments treat emergency conditions of all patients regardless of their ability to pay and is considered a critical element in the "safety net" for the uninsured. However, the federal law established no direct payment mechanism for such care. Indirect payments and reimbursements through federal and state government programs have never fully compensated public and private hospitals for the full cost of care mandated by EMTALA. In fact, more than half of all emergency care in the U.S. now goes uncompensated.[39] According to some analyses, EMTALA is an unfunded mandate that has contributed to financial pressures on hospitals in the last 20 years, causing them to consolidate and close facilities, and contributing to emergency room overcrowding. According to the Institute of Medicine, between 1993 and 2003, emergency room visits in the U.S. grew by 26%, while in the same period, the number of emergency departments declined by 425.[40] Hospitals bill uninsured patients directly under the fee-for-service model, often charging much more than insurers would pay,[41] and patients may become bankrupt when hospitals file lawsuits to collect.

Mentally ill patients present a unique challenge for emergency departments and hospitals. In accordance with EMTALA, mentally ill patients who enter emergency rooms are evaluated for emergency medical conditions. Once mentally ill patients are medically stable, regional mental health agencies are contacted to evaluate them. Patients are evaluated as to whether they are a danger to themselves or others. Those meeting this criterion are admitted to a mental health facility to be further evaluated by a psychiatrist. Typically, mentally ill patients can be held for up to 72 hours, after which a court order is required.

Uninsured rates by state[edit]

The United States Census Bureau regularly conducts the Current Population Survey (CPS), which includes estimates on health insurance coverage in the United States. The data is published annually in the Annual Social and Economic Supplement (ASEC). The data from 1999 to 2012 are reproduced below.[n 1] As of 2012, the five states with the highest estimated percentage of uninsured are, in order, Texas, Nevada, New Mexico, Florida, and Georgia. The five states/territories with the lowest estimated percentage of uninsured for the same year are, in order, Massachusetts, Vermont, Hawaii, Washington, D.C., and Connecticut. These rankings for each year are highlighted below.[1]

Assisting programs for uninsured[edit]

People without health insurance in the United States may receive benefits from patient-assistance programs such as Partnership for Prescription Assistance.[42] Uninsured patients can also use a medical bill negotiation service, which can audit the medical bill for overcharges and errors.
