Growing Superdiversity among Young U.S. Dual Language Learners and Its Implications

[Read This Article/Report]

This report explores the diversity within the DLL population at the national, state, and local level. Although a clear majority of parents of DLLs speak Spanish nationwide (59 percent), this average belies considerable state-to-state variation; in Texas, 78 percent of parents of DLLs speak Spanish, compared to 16 percent in Vermont and Maine. Other languages including Chinese, Tagalog, Vietnamese, Arabic, and a range of less commonly spoken languages are also represented to varying degrees. And even within states that appear relatively homogenous overall, certain counties may still have DLL populations that exhibit superdiversity.
