Mapping Project

In an effort to identify areas of the state that may lack a sufficient number of providers to serve adults seeking dental services under the new Medicaid adult dental waiver program, MDAC mapped the location of Medicaid providers and the dual-eligible population.  The dual eligible population can be found in every county in the state, but the highest concentrations of duals are in Baltimore City, Baltimore County, and on the Eastern Shore. Click here for data showing the 2019 county level distribution of duals.  

In 2018, MDAC, with the help and support of Medicaid and the Maryland Department of Health Office of Oral Health, developed a series of maps showing the relationships between the population, number of providers, and social service agencies that service the dual eligible population.

Maryland population map shows the population of Maryland according to 2012 U.S. Census data. The counties in dark blue are the counties with the largest populations.  The locations of FQHCs, local health department dental clinics, safety net providers, and referral services, as per the 2017 Maryland Oral Health Resource Guide, are indicated by the colored dots on the map.  

MDAC identified more than 100 social services that service the dual-eligible population.  On this map, the dental service providers are shown in yellow, and social services organizations in red.  Not surprisingly, both dental providers and social service agencies are clustered in areas with high populations:  Baltimore City, Baltimore County, Montgomery County, and Prince George’s County.

Maryland dual eligible population map shows the areas of the state with the greatest number of dual eligibles.  Roughly 38% of the dual-eligible population in Maryland is located in Baltimore City and Baltimore County.  Social service agencies that service duals are also clustered in Baltimore City and Baltimore County.

Maryland Dually-Eligible as Percent of County Population shows the percentage of duals by county.  In many rural counties, the percentage of duals is high, while the number of providers is low.

Social service providers are also limited in rural areas with a high percentage of duals.

MDAC very much appreciates the help and support of Medicaid and the Office of Oral Health in developing these maps.
