The United Nations Educational, Scientific and Cultural Organization (UNESCO) defines literacy as the "ability to identify, understand, interpret, create, communicate, compute and use printed and written materials associated with varying contexts. Literacy involves a continuum of learning in enabling individuals to achieve their goals, to develop their knowledge and potential, and to participate fully in their community and wider society."
Some have argued that the definition of literacy should be expanded. For example, in the United States, the National Council of Teachers of English and the International Reading Association have added "visually representing" to the traditional list of competencies. Similarly, in Scotland, literacy has been defined as: "The ability to read, write and use numeracy, to handle information, to express ideas and opinions, to make decisions and solve problems, as family members, workers, citizens and lifelong learners."
A basic literacy standard in many societies is the ability to read the newspaper. Increasingly, communication in commerce or society in general requires the ability to use computers and other digital technologies. Since the 1990s, when the Internet came into wide use in the United States, some have asserted that the definition of literacy should include the ability to use tools such as web browsers, word processing programs, and text messages. Similar expanded skill sets have been called multimedia literacy, computer literacy, information literacy, and technological literacy. Some scholars propose the idea multi-literacies which includes Functional Literacy, Critical Literacy, and Rhetorical Literacy.
Other genres under study by academia include critical literacy, media literacy, ecological literacy and health literacy With the increasing emphasis on evidence-based decision making, and the use of statistical graphics and information, statistical literacy is becoming a very important aspect of literacy in general. The International Statistical Literacy Project is dedicated to the promotion of statistical literacy among all members of society.
