Obamacare is pretty popular in Miami, Fort Lauderdale and other parts of Florida.

Florida's Miami-Dade County had 392,442 plan selections in the latest open enrollment period under healthcare.gov. That's the largest total for any county out of 37 states that use the website to sign up Obamacare enrollees.

The other highest county was right up the road in Broward County with 222,210 signups. The county encompasses the beachfront city Fort Lauderdale.

Rounding out the top five counties are Cook County, Illinois (157,223), Palm Beach County in Florida (136,968) and Maricopa County in Arizona (129,539).

The administration unveiled the county enrollment figures on Thursday, but does not take into account state-based exchanges. A total of about 8.8 million people signed up for Obamacare through healthcare.gov.

It isn't known which county had the lowest Obamacare enrollees as the data does not include counties with 10 or fewer plan selections due to privacy concerns, the administration said.

Some counties with the lowest signups resided in Texas. The county with the lowest amount of signups in the released data was Borden County in Texas with 12. Kennedy County in Texas had 13, Roberts County had 15, Motley County had 24, and two others in Texas were in the 30s.
