Purpose: Bilingual programs in the United States, particularly two-way dual language immersion (TWDL) programs, have been implemented since the 1960s to support the education of English Learner-classified (EL-classified) and language minoritized students. Over the past decade, TWDL programs have grown significantly across the United States. This study examines TWDL program growth in Los Angeles Unified School District, exploring the relationships between program expansion and neighborhood change, enrollment declines, and school choice. These factors have been linked to decreased access to these programs for language minoritized students. Research Methods/Approach: We descriptively examine the neighborhood characteristics of TWDL schools over a 22-year period using publicly available school, census, and housing data, and investigate the relationship between these factors and TWDL emergence. Findings: We find that of the three factors we explored, enrollment change (specifically declining enrollment) and the existence of nearby charter schools are two factors most likely to be associated with TWDL program emergence. We find little evidence that TWDL are primarily emerging in gentrifying contexts. Implications: This study helps us understand general, decade-long trends of TWDL program expansion and dispersion in a district undergoing many of the phenomena described in the literature on this topic.
