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 Bureau, American Community Survey five-year estimates and represents 2020 estimates.
Although the population in Missouri speaks primarily English, this interactive dashboard can be used to further explore other languages spoken in the state. Measures such as the percentage of the population who speak Spanish; those with limited English proficiency; and those who speak a language other than English are shown. Data for a specific county can be viewed by clicking on that county in the map.
