The SegIndex launched in May 2022 with new findings on school segregation. Additional data and resources are coming soon, including:
- Longitudinal datasets on racial/ethnic and economic segregation between schools and neighborhoods at multiple levels of geography (e.g., national, metropolitan area, school district)
- Research papers and briefs on key trends and findings
- Methodological explainers on interpreting measures of segregation
- Code for researchers to create customized segregation estimates
Access the Longitudinal School Demographic Dataset (LSDD):
The LSDD draws on the National Center for Education Statistics’ Common Core of Data to provide school-level race/ethnicity and free/reduced price lunch eligibility data from the 1991-92 to 2020-21 school years. The LSDD imputes missing and implausible data, improves school ID linkages, and links charter schools to geographic districts, among other data quality improvements.

The School Segregation Database will provide longitudinal estimates of segregation between schools and between districts for all states, metros, and districts in the US; among private schools, and between public and private schools; and among and between public traditional and charter sectors. We will estimate segregation with multiple indices for racial segregation, economic segregation, and racial economic segregation.
