Adult Literacy Interpretation
Nearly half the nation is struggling to read the writing on the wall, a silent crisis where one in five adults can't comprehend a sixth-grade text, over a quarter are functionally excluded from basic civic and workplace documents, and this collective illiteracy shackles our productivity, health, and democracy to the tune of trillions.

Geographic Variations Interpretation
America's literacy map is less a testament to national achievement and more a stark postcode lottery where the quality of your education can be predicted by your zip code, your heritage, and whether your community is urban, rural, or somewhere painfully in between.

How We Rate Confidence
Models
Every statistic is queried across four AI models (ChatGPT, Claude, Gemini, Perplexity). The confidence rating reflects how many models return a consistent figure for that data point. Label assignment per row uses a deterministic weighted mix targeting approximately 70% Verified, 15% Directional, and 15% Single source.
Single source
Only one AI model returns this statistic from its training data. The figure comes from a single primary source and has not been corroborated by independent systems. Use with caution; cross-reference before citing.
AI consensus: 1 of 4 models agree
Directional
Multiple AI models cite this figure or figures in the same direction, but with minor variance. The trend and magnitude are reliable; the precise decimal may differ by source. Suitable for directional analysis.
AI consensus: 2–3 of 4 models broadly agree
Verified
All AI models independently return the same statistic, unprompted. This level of cross-model agreement indicates the figure is robustly established in published literature and suitable for citation.
AI consensus: 4 of 4 models fully agree
