The likelihood of dying without medical insurance is a topic that has been widely studied, with research showing a strong correlation between a lack of health insurance and increased mortality rates. Studies have found that uninsured individuals have a higher risk of death compared to those with private insurance, with factors such as socio-economics, health behaviours, and baseline health being accounted for. This disparity in mortality risk is particularly prominent in the United States, which stands alone among industrialized nations in not providing universal health coverage to its citizens. The absence of health insurance leads to limited access to healthcare services, resulting in delayed or missed diagnoses and treatments, ultimately contributing to a higher likelihood of death. While the specific causes of death vary, the lack of insurance disproportionately affects certain illnesses and populations. The impact of insurance status on mortality has been quantified in various ways, including hazard ratios and standardized mortality ratios, providing valuable insights into the relationship between healthcare access and patient outcomes.

The chronically ill uninsured are less likely to receive preventative care
Several studies have found a strong correlation between a lack of health insurance and an increased likelihood of death. For instance, a study by the Institute of Medicine (IOM) in 1993 found a 25% higher death risk among the uninsured compared to those with private insurance. Another study published in the American Journal of Public Health in 2019 found that nearly 45,000 annual deaths are associated with a lack of health insurance, with uninsured working-age Americans having a 40% higher risk of death than those with private insurance.
The chronically ill who are uninsured are less likely to receive preventative care and primary care. This is due to a variety of factors, including the high cost of insurance, a lack of access to coverage through employment, and a lack of awareness of coverage options. As a result, they are more likely to delay or forgo necessary medical care, leading to negative health outcomes. For example, they may not be able to afford prescription medications or follow-up care for chronic conditions, increasing the risk of preventable hospitalizations and missed diagnoses.
Research has consistently shown that uninsured individuals are less likely to receive preventive care and services for major health conditions and chronic diseases. They are more likely to be hospitalized for avoidable health problems and experience declines in their overall health. In addition, when they are hospitalized, they receive fewer diagnostic and therapeutic services and have higher mortality rates.
Gaining health insurance has been shown to improve access to healthcare and reduce the adverse effects of being uninsured. For example, a study of Medicaid expansion in Oregon found that adults who gained coverage were more likely to have outpatient visits and receive prescriptions, and they experienced improved mental health in the short term. Similarly, providing Medicaid coverage to previously uninsured adults significantly increased their chances of receiving a diabetes diagnosis and diabetic medications.
Expanding access to health services is crucial for reducing health disparities and improving health outcomes, especially for racial and ethnic minority groups who may face additional barriers to care.

Intermittently uninsured people are more likely to die than insured people
A study by the Harvard Medical School and Cambridge Health Alliance found that nearly 45,000 annual deaths are associated with a lack of health insurance. This figure is about two and a half times higher than an estimate from the Institute of Medicine (IOM) in 2002. The study found that uninsured, working-age Americans have a 40% higher risk of death than their privately insured counterparts, up from a 25% excess death rate found in 1993. The chronically ill uninsured are less likely to have access to preventative and primary care, and the discontinuity of insurance is also harmful. Intermittent insurance coverage is common and accelerates the decline in health among middle-aged persons. Those who are intermittently uninsured are more likely to die than the insured.
The study's lead author, Dr Andrew Wilper, an instructor at the University of Washington School of Medicine in Seattle, commented:
> The uninsured have a higher risk of death when compared to the privately insured, even after taking into account socioeconomics, health behaviours, and baseline health. We doctors have many new ways to prevent deaths from hypertension, diabetes, and heart disease — but only if patients can get into our offices and afford their medications.
Another expert, Lucien Wulsin, director of the Santa Monica, California-based Insure the Uninsured Project, supported the research. He observed that the study seems to validate what is already known about the lack of access to healthcare services for the uninsured. Wulsin commented:
> I saw it as very much validating the earlier [IOM] study, that being without health insurance means that you have a greater likelihood of mortality because you don’t get the care when you don’t have the health insurance until ‘too-little too late.
The United States is the only industrialized nation that does not provide health coverage to all its citizens. Most uninsured people are in low-income families, and many cite the high cost of insurance as the main reason they lack coverage. People without insurance coverage are less likely to access care and more likely to delay or forgo it because of the costs. Uninsured people often face unaffordable medical bills, and nearly half (49%) of uninsured adults say they have difficulty affording healthcare costs, more than double the share of those with private insurance (21%).

The risk of death is higher for men, smokers, heavier drinkers, and older people
The likelihood of dying is a topic that medical insurance companies are interested in, as they can use this information to assess risk and set premiums. Various factors influence a person's likelihood of dying, and these factors can be used to predict mortality risk.
One such factor is gender, with men having a higher risk of death than women. This is partly due to men being twice as likely to die from unintentional injuries, which are the third leading cause of death for men, after heart disease and cancer. Men are also ten times more likely to be killed at work, often in high-risk jobs such as construction, manufacturing, and transportation. Masculine stereotypes and societal expectations of men can also contribute to this increased risk, as men are encouraged to take risks and may be reluctant to admit physical pain or seek help when needed.
Smoking is another significant factor that increases the likelihood of dying. Overall mortality among smokers is about three times higher than among non-smokers, with smoking-related diseases, including cancer, respiratory and vascular disease, and heart disease, being the major causes of excess mortality among smokers. Smoking increases the risk of dying from coronary heart disease by almost four to five times, and it raises the risk of dying from bronchitis and emphysema by 12 to 17 times. Quitting smoking before the age of 40 can reduce the risk of dying from smoking-related diseases by about 90%.
Excessive alcohol consumption is also linked to a higher risk of death. Heavier drinkers face increased mortality risks from all causes, alcohol-related cancers, liver-related causes, and, in some cases, cardiovascular disease. Episodic heavy drinking, defined as having 5 or more drinks on at least three days, further increases the risk of all-cause mortality and death due to liver-related diseases and, in some cases, cardiovascular disease.
Lastly, older people have a higher risk of death. This is because, as we age, our cells become damaged by injury, stress, and DNA mutations, causing our organs to deteriorate. This makes us more susceptible to diseases such as cancers, cardiovascular diseases, infectious diseases, and dementias, which increase overall death rates. However, it is important to note that death rates in older people are much lower today than in the past. For example, those born in 1970 Sweden had an 11 times lower annual death rate at age 50 than those born in 1800.

The yearly probability of dying is based on age, sex, and other factors
The probability of dying within a year is a statistical estimate of the likelihood of a person's death within that time frame. This estimate is based on factors such as age, sex, and other variables. For instance, mortality rates differ significantly between the ages of 10 (1 death per 10,000) and 85 (10 deaths per 10,000). The yearly probability of dying increases with age, while the yearly probability of living decreases.
Mortality tables, also known as actuarial or life tables, are used to calculate the percentage of people in a specific group who are likely to die within a given time frame. These tables are commonly used in the insurance industry to set life insurance premiums and annuity pricing. The Internal Revenue Service (IRS), for instance, publishes life expectancy tables that taxpayers use to determine their annual required minimum distributions (RMDs) from retirement accounts.
Various factors influence the probability of dying, and these factors are considered in studies examining the link between health insurance coverage and mortality rates. One study found that uninsured, working-age Americans had a 40% higher risk of death than those with private insurance. The risk factors for death among the uninsured were higher for men, smokers, heavier drinkers, and older individuals. Additionally, discontinuity of insurance coverage is harmful, as those with intermittent insurance are more likely to die than those with continuous coverage.
The impact of lacking health insurance on mortality rates is evident in specific states and regions. For example, California had the highest number of excess deaths due to a lack of health insurance, with 5,302 deaths in 2005. This issue is not limited to a single state, as nearly 45,000 annual deaths across the United States are attributed to a lack of health insurance. This number exceeds the deaths caused by common diseases such as kidney disease. The increased risk of death among the uninsured is associated with delayed access to necessary medical care and improvements in treatment options for insured individuals.

Lack of health insurance is the third leading cause of death for Americans aged 55-64
A 1993 study found a 25% higher risk of death among uninsured US adults compared to those with private insurance. The study was replicated in 2009 with updated census data, and the findings were similar, with a 40% higher risk of death for uninsured people. This is because uninsured people are less likely to have a regular source of care outside of emergency departments and often delay or forgo medical care due to high costs. They also pay more for medical care when they do receive it, as they cannot negotiate discounts with hospitals and doctors.
The lack of health insurance is a significant issue in the US, with an estimated 18,000 to 27,000 adults aged 25-64 dying due to a lack of coverage in 2006. The number of deaths associated with a lack of health insurance exceeds those caused by common conditions such as kidney disease. The risk of death is likely even higher, as these estimates are based on older data, and the quality of care for insured individuals has improved since then.
The issue of lacking health insurance is more prevalent in certain states; California led the nation in excess deaths from a lack of health insurance in 2005, with 5,302 deaths. The percentage of uninsured people varies across states, ranging from 10% in Minnesota to 28% in Texas.
The impact of lacking health insurance is not limited to adults; children and adolescents are also affected. A study that analysed data from participants aged 17 to 64 years found that among all participants, 3.1% died. After adjusting for age and gender, the hazard ratio for mortality among the uninsured was 1.80, which further increased to 1.40 after additional adjustments for race/ethnicity, income, education, health status, body mass index, leisure exercise, smoking, and regular alcohol use.
The high number of deaths associated with a lack of health insurance highlights the importance of policymakers ensuring that as many people as possible have access to healthcare services. By focusing on primary care and preventive services, individuals can receive timely and appropriate care, reducing the risk of serious outcomes from untreated illnesses.

Frequently asked questions
Studies have shown that uninsured people have a higher risk of death compared to those with private insurance. The uninsured are more likely to go without necessary care, leading to an increased risk of mortality.
The availability of medical care and treatment options significantly impact mortality rates. Uninsured individuals often experience discontinuity of care, making it difficult to manage chronic illnesses effectively, which can lead to premature death.
Yes, demographic factors such as age, gender, race, and lifestyle choices (e.g., smoking, alcohol consumption) contribute to varying mortality rates among the uninsured. For example, studies have found that the risk of death is higher for men, smokers, and older individuals without insurance.
Life expectancy estimates are used to determine the likelihood of an individual attaining a certain age before death. These estimates are influenced by factors such as current age, sex, and health status. Insurance companies use these estimates to set premiums and pricing, assessing an individual's mortality risk.
Yes, certain conditions, such as hypertension, diabetes, and heart disease, have improved treatments for insured individuals, increasing the survival rate. However, the lack of access to these treatments for the uninsured contributes to a higher likelihood of mortality from these diseases.
