In 2014, 34 percent of Americans age 18-64 didn't visit — or even speak with — a primary care physician, according to a CDC report.
In Montana, that number was highest, at 48.1 percent, with 10 other states — South Dakota, Alaska, Nevada, New Mexico, South Carolina, Idaho, Nebraska, Texas, Florida and California — also reporting above average numbers.
Whether states had state-based or federally facilitated marketplaces had little impact on whether residents saw providers, but rates were lower in states with partnership marketplaces.
Additionally, many adults in the U.S. reported not having a go-to place to receive care in 2014. That number ranged from 2.8 percent in Vermont to 26.7 percent in Nevada, according to the data. Those rates were slightly lower in states with Medicaid expansion.
