Although the ACA has significantly reduced the percent of Americans who are uninsured, we have not yet come close to universal coverage. This has become a topic of focused debate among Democratic primary candidates. Short of achieving full coverage by passing a single-payer plan (which seems very unlikely in the near future), further gains in insurance coverage will come through means available through the ACA.
It’s worth revisiting, therefore, exactly who constitute the uninsured at this point. A better understanding could allow policymakers and advocates to focus their efforts on those populations. A recent report from the Robert Wood Johnson Foundation and The Urban Institute covered just that.
