WASHINGTON, United States: According to a government survey of literacy an estimated one in 20 American adults is not literate in English, which means 11 million people lack the skills to perform everyday tasks, and 30 million can do little more than sign a document.
 
The nation's adults made no progress from 1992 to 2003 in their ability to read a newspaper, a book or any other prose arranged in sentences and paragraphs. They also showed no improvement in comprehending documents such as bus schedules and prescription labels.
 
The adult population did make gains in handling quantitative tasks, such as calculating numbers found on tax forms or bank statements. But even in that area of literacy, the typical adult showed only basic skills, enough to perform simple daily activities.
 
Perhaps most sobering: Adult literacy dropped or was flat across every level of education, from people with graduate degrees to those who dropped out of high school.
 
Inside the numbers, black adults made gains on each type of task tested in the National Assessment of Adult Literacy, run by the Education Department. Hispanics, though, showed sharp declines in their ability to handle prose and documents.
 
White adults made no significant changes except when it came to computing numbers, where they got better.
 
The results are based on a sample of more than 19,000 adults, age 16 or older, in homes, college housing or prisons. It is representative of a population of 222 million adults.
 
The 11 million adults who are not literate in English include people who may be fluent in another language, such as Spanish, but are unable to comprehend text in English.
