The Missouri Economic Research and Information Center tracks language diversity for the state to help inform the public, businesses, agencies, organizations, and other stakeholders of the unique language diversity across Missouri. The language data series also helps determine English Language Proficiency for purposes of translation requirements. This data is pulled and analyzed from the U.S. Census, American Community Survey five-year estimates and represents 2019 estimates (2015-2019).
The American Community Survey five-year estimates includes a general language survey that can be updated annually and a more detailed survey of over forty different languages spoken in Missouri statewide. Missouri county language details include language groups that cover Spanish, Indo-European, Asian and Pacific Islander, Serbo-Croatian, and other languages.
