Math Gaps Mirror Socioeconomic Segregation

The PISA 2022 U.S. mathematics results show measurable score differences across student groups (by income, race/ethnicity, and school characteristics). Those subgroup gaps track socioeconomic sorting and school resource differences, not just individual ability, and so highlight where policy (funding, school assignment, early childhood support) can change population outcomes. — If math‑achievement gaps largely reflect socioeconomic segregation, then debates about school funding, zoning, and early interventions should be central to discussions about economic mobility and labor supply.
