The literacy rate is the total number of literate persons (people able to both read and write) in a given age group, expressed as the percentage of that age group. The adult literacy rate measures literacy among persons age 15 and older.
According to the National Center for Education Statistics, about four out of five U.S. adults (79%) have medium to high English literacy skills. These literacy levels are sufficient to compare and contrast information, paraphrase, and make low-level inferences. This means that about one in five U.S. adults (21%) have low literacy skills, translating to about 43.0 million adults.
Of those who have low English literacy skills, 35% are White, 2% of whom are born outside of the U.S.; 23% are Black, 3% of whom are born outside of the U.S.; 34% are Hispanic, 24% of whom are born outside of the U.S.; 8% are of other races/ethnicities. Non-U.S.-born adults comprise 34% of the U.S. population with low literacy skills.
