Key Language Findings for Maryland

How Language Use Varies Across Maryland Counties

Language patterns differ sharply by county. Spanish is the leading non-English language across most of Maryland, but county-level rankings show large local communities speaking African languages, Chinese, French, Korean, Russian, Tagalog / Filipino, German, and other languages.

Montgomery County has both the largest number of residents speaking a language other than English at home and the highest share relative to its age-5+ population, at 39.6%. In Garrett County, other West Germanic languages are the leading non-English language, showing how statewide rankings can differ substantially at the local level.

English Proficiency and Language Access in Maryland

Speaking a language other than English at home does not necessarily mean someone has limited English proficiency. Census table B16001 also separates language groups by whether residents report speaking English "very well" or less than "very well," providing additional context for organizations planning language access services.

About the Data

Data on this page comes from the U.S. Census Bureau's American Community Survey 2011–2015 5-Year Estimates, table B16001, Language Spoken at Home by Ability to Speak English for the Population 5 Years and Over. Statewide and county estimates use the same Census table so the figures can be compared consistently across the page.

The estimates describe languages spoken at home among residents age 5 and older. Census estimates include margins of error, particularly for smaller counties and less common language groups.
