The American Community Survey (ACS) provides detailed information on limited English proficiency, which includes 29 individual languages and 11 grouped languages. In order to provide translation of vital documents, as guided by federal Title VI regulations, it is necessary to disaggregate the 11 grouped languages in the ACS in order to estimate the constituent individual languages. Local public schools data proves to be useful in unpacking and providing individual language estimates for the grouped languages in the ACS. Considerations include developing a crosswalk between the 100-plus individual languages in the schools data and the 11 grouped languages in the ACS, as well as reconciling distinct geometries (i.e., Census tracts, school attendance boundaries) and universes (i.e., population 5 years and over, student population).
