This plate extends Du Bois's 1900 methodology — count, visualize, present to the world — to the same subject one hundred and twenty-six years later. The visual grammar preserves Du Bois's plate-mount conventions: hand-drawn double border, Libre Caslon italic titles in English and French, geometric bars, the Du Bois 1900 palette (ink, blue, green, gold, red). The data is rendered at a single consistent scale so that the 1900 baseline and the 2020 figure share the same axis; in 1900 the bar is effectively a hairline next to the 2010 peak.
This is a preview plate for conversation, drafted April 11, 2026. The values above are approximate to within roughly 10% for the illustrative years shown. The production plate for The Du Bois Reappraisal, Volume I, 2026 will source exact figures from NCES Digest of Education Statistics Table 306.10 for 1976 forward, and from IPEDS / Census IPUMS / The College-Bred Negro (Du Bois, 1900) for pre-1976 years. No figure in the production plate will be uncited. Any number that cannot be cited to a primary source will not appear.
