McKinsey & Co. conducted a study on enrollment through Healthcare.gov and the state insurance exchanges using data as of Feb. 1. At that time, 3.3 million had enrolled. McKinsey concluded that only 14 percent, or about 500,000 individuals, were "actual uninsured who have actually gained health coverage." An additional 13 percent of uninsured individuals had signed up for Obamacare but had not paid the premium. Of those who had signed up by that time, 73 percent either had insurance and preferred to choose a plan on the exchange or enrolled because their individual plans were canceled.
