According to a study conducted in late April by the U.S. Department of Education and the National Institute of Literacy, 32 million adults in the U.S. can't read. That's 14 percent of the population. 21 percent of adults in the U.S. read below a 5th grade level, and 19 percent of high school graduates can't read.
The current literacy rate isn't any better than it was 10 years ago. According to the National Assessment of Adult Literacy (completed most recently in 2003, and before that, in 1992), 14 percent of adult Americans demonstrated a "below basic" literacy level in 2003, and 29 percent exhibited a "basic" reading level.
