Medicaid Enrollment, Average Monthly Enrollment as a Percentage of the Population by County, All Persons, New Mexico,

In 2018, 840,486 New Mexico children and adults were enrolled in Medicaid each month, on average. Over 40% of Medicaid enrollees were children under age 21 years.

Why Is This Important?

Medicaid provides health coverage for those New Mexicans living below a certain percentage of the federal poverty level, and provides coverage for almost half of New Mexico's children. People with health coverage are more likely to receive preventive medical care and are consequently less likely to suffer from preventable illnesses and complications of those illnesses.


The monthly percentage of the population enrolled in Medicaid, averaged over the months in the measurement period. Enrollment varies from one month to the next. The average monthly enrollment was used to compute these percentages.
