• Find county-level data on the number, share, and linguistic diversity of LEP individuals in LEP Data Brief compiled by the Migration Policy Institute's National Center on Immigrant Integration Policy. The county-level data offer two different counts - LEP individuals as a percentage of the total county population as well as in absolute numbers - by language or language group across 3,221 counties in the United States (including Puerto Rico). (Note: the national and state-level estimates in the LEP Data Brief might not match exactly the estimates shown in the "Language and Education" Fact Sheet because different years of ACS were used).
