Federal numbers released today show that 120,000 Arizonans selected health plans via the federal marketplace during the open enrollment period, which ended March 31.

Nearly 80 percent of those purchasers qualified for financial assistance with their insurance plans through President Obama's health plan, numbers from the U.S. Department of Health and Human Services show.

Border states, including Arizona, had highest shares of Latinos among marketplace plan selections, with Texas at 33.6 percent, New Mexico at 31.1 percent, Arizona at 24.2 percent, followed by Florida at 19.2 percent.

Another 101,000 people signed up for Medicaid via the marketplace during the enrollment period, the data says. In Arizona, Medicaid is called the Health Care Cost Containment System (AHCCCS).

Other highlights of the new data:

• 21% of those who selected marketplace plans were under the age of 18

• 24% were between the ages of 55 and 64

Arizona did not run its own marketplace, which is why state residents had to go to a federally-run portal to access federally subsidized health insurance.

About 1.2 million state residents were uninsured prior to open enrollment, which began Oct. 1.
