About 1,300 Michigan residents selected a health insurance plan in the first month of enrollment under the federal health law.
The number released Wednesday by the Obama administration confirms the problems people are having in enrolling in private plans offered on a federal website. Michigan is among 36 states to let the federal government run the insurance exchange instead of having its own.
The fewer than 27,000 people who signed up nationally in October are one-fifth of the number expected.
In Michigan, roughly 34,000 residents who applied for coverage have been ruled eligible for the exchange. About 12,500 are eligible for tax credits to offset some of their premiums.
Enrollment runs through March.
The state estimates at least 365,000 people could sign up on the market in 2014.
