The Effect of Community Uninsurance Rates on Access to Health Care among the Insured

by Isabella Antonio

Abstract 

While the direct effects of being uninsured have been studied extensively, there is significantly less research on how a high community uninsured rate can impact health care access for insured individuals. Using data from SMART BRFSS, I examine the effect of community uninsured rates on access to health care for insured individuals ages 18 to 64 years old. Controlling for MMSA-level fixed effects and year fixed effects, I estimate the effect of community uninsurance on the likelihood of an insured individual skipping care due to cost, the likelihood of an insured individual having at least one personal doctor, and the likelihood of an insured individual delaying a physical exam, cholesterol check, or pap smear. Results suggest that a 10 percentage point increase in the community uninsured rate decreases the likelihood of an insured individual having at least one personal doctor by 0.304 percentage points and increases the likelihood of delaying a physical exam, cholesterol check, or pap smear by 0.590 to 2.31 percentage points. These findings suggests that policies aimed at reducing the uninsured rate, such as the Affordable Care Act and Medicaid expansion, may produce widespread benefits for all Americans, both the uninsured and the insured.
