[H]ere, once again, is the complete 2015 ACA enrollment graph, showing the rough breakout of all 32.3 million people whose current healthcare coverage is either wholly or partly due specifically to the Affordable Care Act.
Again, that does not mean that all 32.3 million were uninsured to begin with. By my best estimates based on the available data, I estimate that around 19 million already had some form of insurance coverage. Around 11 million were uninsured prior to January 2014, and around another 2 million were uninsured prior to January 2015.
It does mean that 32.3 million people have quality insurance that covers more than just catastrophic care. What's not encompassed in this chart is how much coverage has changed for every American with health insurance—the preventive care that no one has to pay extra for, the peace of mind from knowing that a serious health issue won't keep them from getting or keeping insurance.
