1. There have been 846,184 applications completed. Because many of these applications are for families, they cover 1,509,883 people. But only 106,185 have chosen an actual plan.

2. It's not quite right to say 106,856 have actually bought a plan. The White House is also counting people who have placed a plan in their shopping cart but haven't yet paid.

3. Ten percent of people who have been determined eligible to enroll have actually done so. The rate is higher in state-based marketplaces (21 percent) than in those run by the federal government (4 percent).

4. About 75 percent of the sign-ups come from the 14 state-based marketplaces. Those marketplaces have had about 79,000 people sign up, compared with the 27,000 people who have purchased coverage in the federal marketplace.

5. California's enrollment accounts for a full third of all sign-ups. The state has had just over 35,000 people sign up.

6. North Dakota has the fewest enrollees. Exactly 42 people have signed up.

7. Lots of shoppers on HealthCare.gov are turning to paper applications. Thirty-three percent of sign-ups in the federal exchange have been done offline. In states, that number stands at just 3 percent.

8. The "woodwork" effect is real. 

9. The numbers would be a lot higher if HealthCare.gov worked as well as some state-based marketplaces.
