More than five million people have now enrolled in private health coverage through Obamacare, the Obama administration announced Monday.

The figure, announced via a blog post, provided another data point as the law’s open enrollment comes to a close at the end of March. The administration said 4.2 million people had enrolled by the end of February, which means about 800,000 have signed up in March.

Obamacare is still set to fall well short of the Congressional Budget Office’s original enrollment projection of 7 million, but the CBO’s revised projection of 6 million — offered after HealthCare.gov’s disastrous launch — seems attainable.

Administration officials and health policy experts have long said they expected enrollment to accelerate ahead of the March 31 deadline.
