Literacy in the United States

Rates of literacy in the United States depend on which of the various definitions of literacy is used. Governments may label as literate those individuals who can read a couple of thousand simple words they learned by sight in the first four grades in school. Other sources may term such individuals functionally illiterate if they are unable to use basic sources of written information like warning labels and driving directions. The World Factbook prepared by the CIA describes the definition of literacy in most countries as "age 15 and over can read and write." The literacy rates are not completely measurable.
