The proportion of White students attending public schools declined by 39 percentage points between 1955 and 2020.

In its data analysis, GAO used “White alone, not Hispanic” after the category was available starting in 1993. GAO used “Black alone or in combination with another race” and “Asian alone or in combination with another race” to characterize Black and Asian populations respectively in the years those data were available, starting in 2003.
