Critical Race Spatial Analysis of Two-Way and One-Way Dual Language Program Distribution Among Texas Public School Campuses, 2020–2021 (ICPSR 308283)
This data collection was assembled to examine the geographic distribution of two-way dual language (TWDL) and one-way dual language (OWDL) bilingual education programs across Texas public school campuses during the 2020–2021 academic year. Campus-level bilingual program enrollment data were obtained from the Texas Education Agency (TEA) through a formal public information request submitted under the Texas Public Information Act. Geographic coordinate data were obtained from TEA's publicly available campus reference file for the 2021–2022 school year. Demographic context variables were drawn from the 2017–2021 American Community Survey 5-Year Estimates (U.S. Census Bureau), including county- and census tract-level data on nativity (Table B05012) and median household income (Table S1903). Geographic boundary files were obtained from the U.S. Census Bureau TIGER/Line Shapefiles (2021) at both the county and census tract levels.
The collection includes campus-level enrollment counts for six bilingual program types: TWDL, OWDL, ESL content-based, ESL pull-out, transitional bilingual early exit, and transitional bilingual late exit. Enrollment counts for small cell sizes were suppressed by TEA for privacy protection. The collection also includes derived variables consisting of normalized program enrollment ratios calculated as program-specific enrollment divided by total campus enrollment. Campus records include geographic coordinates, school type classification (public, charter, or alternative), district identifiers, and county identifiers. The collection additionally includes two derived shapefiles, one at the county level and one at the census tract level, in which TEA-restricted campus enrollment data are not present; these shapefiles contain only Census Bureau demographic variables (immigrant density and median household income) merged into TIGER/Line boundary geometry. Geographic coverage is the state of Texas. The data describe the 2020–2021 academic year.
