Despite its seemingly endless political and financial travails, Obamacare has taken a big bite out of the number of uninsured Americans since it was enacted in 2010. An estimated 20 million more people are now covered by private health insurance obtained through subsidized government exchanges or expanded Medicaid for the poor.
But as the curtain begins to ring down on President Obama’s administration, roughly 20 million to 24 million people still lack health insurance, a huge piece of unfinished business that will be left to the next president and a new Congress to address. And that raises two interesting questions: precisely who are the uninsured today and why haven’t they been able to obtain coverage?
A national survey by the Commonwealth Fund conducted last February through April finds “notable shifts” in the demographic composition of the uninsured since the Affordable Care Act first took effect in 2014.
A quick snapshot of the detailed findings tells the stories of millions of people either purposefully rejecting health care insurance, not qualifying for a federal program, or being unaware of their options to acquire coverage.
