A Dynamic Approach to the Determinants of Immigrants’ Language Proficiency: The United States, 1980–20001

This article proposes a dynamic perspective on immigrants’ language proficiency. Hypotheses are formulated about immigrants’ language skills at arrival and about the speed with which immigrants learn the language thereafter. It pools data from the 1980, 1990, and 2000 U.S. Censuses, and uses a synthetic cohort design to analyze the language skills of immigrants within the first 20 years after migration. Multilevel models show that higher educated immigrants arrive with better language skills and learn the language quicker. Group size has a double‐negative effect: it attracts less skilled immigrants, and it hampers language learning. These and other determinants are discussed in light of current research on immigrants’ second‐language proficiency.
