New data from insurance company regulatory filings show that enrollment in the individual health insurance market declined significantly last year—by 10 percent, or 1.8 million people.

Over the three years prior to the implementation of Obamacare (2011 through 2013), enrollment in the individual market was basically stable—fluctuating narrowly between 11.8 million and 12 million persons. With the introduction of Obamacare, enrollment jumped to 16.5 million in 2014, peaked at 17.7 million in 2015, and then declined to 17.1 million in 2016.
