Interpretation
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.

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.
