Insurance Status by State Medicaid Expansion Status: Early Release of Estimates From the National Health Interview Survey, 2013–September 2014

May 21, 2015

Under the Affordable Care Act, states have the option to expand Medicaid coverage to all eligible persons with incomes up to 138% of the federal poverty level (FPL). Previous research has shown that there have already been significant decreases in the percentages of persons who were uninsured between 2013 and the first 9 months of 2014.

Using data from 2013 and the second and third quarters (April through September) of the 2014 National Health Interview Survey (NHIS), a new NCHS report examines changes in the percentage of persons who were uninsured, by state Medicaid expansion status, age, and poverty status.

Data from the second and third quarters of the 2014 NHIS were chosen for this analysis because they capture the surge in enrollment in the Health Insurance Marketplace and state-based exchange plans that occurred in March and the beginning of April 2014. Data from the fourth quarter of the 2014 NHIS are not yet available.

Key Findings from the Report:

  • The percentage of adults aged 18–64 who were uninsured at the time of interview decreased from 20.4% in 2013 to 15.9% in April–September 2014.
  • Adults aged 18–64 with family incomes less than or equal to 138% of the FPL in Medicaid expansion states had a larger decrease in the percentage uninsured (10.2 percentage points) than those with similar income in nonexpansion states (3.3 percentage points) from 2013 to April–September 2014.
  • Between 2013 and April–September 2014, the percentage of uninsured adults aged 18–34 with incomes less than or equal to 138% FPL decreased 9.1 percentage points in Medicaid expansion states, compared with only 0.7 percentage points in nonexpansion states.
  • The greatest absolute decrease in the percentage uninsured from 2013 to April–September 2014 (12.1 percentage points) was among adults aged 45–64 with incomes less than or equal to 138% FPL in Medicaid expansion states.

Report card for Nation’s health focuses on young adults aged 18-29

February 18, 2009
Young adults in the United States aged 18-29 face a number of health challenges, including increases in obesity, high injury rates, and a lack of insurance coverage compared to other adults, according to the latest report on the nation’s health from NCHS.
  • Obesity rates have tripled among young adults in the past three decades, rising from 8 percent in 1971-74 to 24 percent in 2005-06.
  • In 2006, 29 percent of young men were current cigarette smokers compared to 21 percent of young adult women.  
  • In 2005, unintentional injuries (‘‘accidents’’), homicide, and suicide accounted for 70 percent of deaths among young adults 18–29 years of age. Three-quarters of the 47,000 deaths in this age group occurred among young men. 
  • In 2006, young adults aged 20–24 were more likely to be uninsured (34 percent) than those aged 18–19 (21 percent) and those aged 25–29 (29 percent).

New Ambulatory Care Report

June 29, 2007

The Centers for Disease Control and Prevention today issued a new report, “Ambulatory Medical Care Utilization Estimates for 2005,” which contains information on patient visits to emergency departments, outpatient clinics, and physician offices.

Highlights of the report:

There were over 1.2 billion patient visits to physician offices, hospital outpatient clinics, and emergency rooms in 2005. Over the past decade, rates of visits per population increased for all types of health care settings studied.

In the emergency department, the visit rate for patients with no insurance was about twice that of those with private insurance.

Conversely, patient visits to physician offices were higher for individuals with private health insurance compared with uninsured persons.

Over 29 percent of all ambulatory care visits were for chronic diseases such as heart disease and diabetes, and one in four were for preventive care, including check-ups, prenatal care, and post-surgical care.

There were 2.4 billion medications prescribed or administered at these visits.

Health Insurance Coverage

June 26, 2007

The National Center for Health Statistics has released its estimates of health insurance coverage in the United States derived from household interviews conducted under the aegis of the Health Interview Survey. The report is entitled Early Release of Health Insurance Estimates Based on Data From the 2006 National Health Interview Survey.

As an aside, the Census Bureau conducts a similar study, using a different methodology so when comparing insurance coverage over time you have to be careful to make an apples-to-apples comparison.

Top line results:

The study examines data collected from interviews in over 100,000 households nationwide. Some of the highlights include:

  • In 2006, there were 43.6 million Americans of all ages who did not have health insurance (at the time of the interview), or 14.8% of the population.
  • Among working-age Americans (those ages 18-64), there were 19.8% who did not have health insurance in 2006, a slight increase from 18.9% in 2005.
  • Approximately 9.3% of children under the age of 18 did not have health insurance in 2006, a decrease from 13.9% in 1997.
  • In 2006, the percentage uninsured at the time of interview among the 20 largest states ranged from 7.7% in Michigan to 23.8% in Texas.
