According to Gallup, “After four years of Affordable Care Act implementation, the percentage of adults with no health care insurance has hit 12.2 percent”
So is that an increase or a reduction? The linked article continues:
“In the last quarter of 2016, the percentage of uninsured hit a record low of 10.9 percent. A year later, in the last quarter of 2017, the percentage of uninsured increased by 1.3 points—the largest single-year increase Gallup has seen since it began tracking the measure in 2008.”
Based on US population of approximately 320 million, each 1-percentage point increase to the uninsured rate is about 3.2 million people. Do the math. The number of uninsured Americans increased by more than 4 million just at one enrollment - 2017! (For any progressives who may struggle with math, 3.2 x 1.3 = 4.1). Don't forget the premiums for 2017 were set B.T. - Before Trump.
Also note that after 4 years of Obamacare, and despite the “mandate”, Americans age 26-34 have the highest uninsured rate = 20.1%. Can’t say that’s a surprise either.
