To start, the figure doesn’t reveal how many people actually paid for health plans as of Dec. 24. Though payment is what typically makes enrollment official, up to this point, CMS has counted people as being “enrolled” if they merely went through the process of picking a health care plan.

Additionally, CMS still hasn’t provided a demographic breakdown of those who have signed up for insurance through the exchange, which is a key metric for measuring the success of Obamacare, because the exchanges need a critical mass of young and healthy individuals to offset the cost of covering older and sicker enrollees and those with pre-existing conditions.
