Overview

Lack of Health Insurance is the percentage of the population not covered by private or public health insurance. The 2015 ranks are based on 2013 and 2014 data from the Annual Social and Economic Supplement Bureau of the Current Population Survey.

The prevalence of the population without health insurance ranges from a low of 3.5% in Massachusetts to a high of 20.6% in Texas. Nationally, 13.1% of the US population are uninsured, down from 14.6% in the 2014 Edition and 15.6% in the 2013 Edition. 

Public Health Impact

Individuals without health insurance have more difficulty accessing the health care system, are often unable to participate in preventive care programs, and have more unmet health needs than those with health insurance.[1] In addition to decreasing quality of life, these unmet health needs can burden the health care system. Unmet health needs can develop into more serious conditions requiring more costly treatments. Lack of health insurance often leads to more emergency department visits that can cost up to 10 times more than treatment in a clinic.[2] Research shows uninsured individuals have worse health outcomes.[3] Uninsured use preventive health care services less, and cancer mortality rates are higher.[4]The unmet health needs of the uninsured increase the mortality risk 25% compared with those with insurance, accounting for an estimated 18,000 excess deaths annually.[5]

The most significant barrier in accessing quality health care for minority populations is lack of health insurance.[6] Per the Institute of Medicine’s 2002 report on health disparities, racial and ethnic minorities accounted for more than half of the 50 million uninsured Americans in 2000.[7] The 2010 Affordable Care Act is bringing down the uninsured rate through expanded Medicaid eligibility requirements and tax subsidies for individuals in lower income brackets. Early evaluations detected a 5.2% decrease in the percentage of adults without insurance in the second quarter of 2014—a marked decline less than 1 year after the initial enrollment period.[8] This decline corresponded with improvements in access measures that include   the percentage of adults with a personal doctor and the proportion of adults not able to afford medical care.[9]

Increasing the number of Americans with health insurance is important in improving health outcomes and decreasing health care spending, but this step forward in isolation is limited. A 2011 study showed that a combination of 3 strategies—expanding health insurance coverage, delivering better preventive and chronic care, and focusing on community prevention—is more effective at saving lives and money than implementing any of these strategies alone.[10]   

A Healthy People 2020 leading health indicator is to increase the proportion of people with medical insurance to 100% over this decade.
