WASHINGTON — A little more than 1 million people renewed health coverage or signed up for the first time through HealthCare.gov around the start of open enrollment, which coincided with a GOP election sweep likely to scramble President Barack Obama’s signature law.

The figures released Wednesday by the Obama administration represent steady sign-ups but no enrollment surge so far.

Still, officials said they have seen an outpouring from consumers wanting to make sure the government knows how important the endangered program has become in their lives.

“Health insurance is linked to independence and economic freedom,” said Andy Slavitt, head of the Centers for Medicare and Medicaid Services, which runs the nation’s major coverage programs.

Overall, the new number is fairly comparable to early sign-ups last year, but the share of new customers is down. They accounted for 24 percent of the total so far this year, compared with 34 percent in the first two weeks of last year’s open enrollment season. Nearly 1.1 million people had enrolled last year by about the same time.

The 2017 early sign-up figures are for Nov. 1-12, while the closest numbers from last year cover a full two weeks, which may explain some of the shortfall. The administration said 53,000 more customers signed up in the first 12 days this year than in the same period last year.

Still, several numbers were down, including call center volume, HealthCare.gov users, and window-shoppers.
