The use of computers and the Internet by students has increased rapidly in recent years. In 2001, computer and Internet use was more widespread among school-age children and adolescents than among adults. The now commonplace use of these technologies follows the installation of computers and Internet access in nearly all public schools and in a majority of households with children by 2000. This Issue Brief describes the percentages of students in grades 12 or below who used computers or the Internet in 2003. Data for this Issue Brief come from the October 2003 Computer and Internet Use Supplement to the Current Population Survey (CPS). The CPS is a sample survey representative of the civilian noninstitutional population in the United States. The survey is conducted in approximately 56,000 households each month. In October 2003 it collected information regarding 29,075 children enrolled in nursery school through 12th grade. A member of each household who is at least 15 years old provides information about household members. As a result of this data collection method, data regarding computer and Internet use by students were not collected directly from students in most cases, but from another member of the household; this method is a potential source of error. Computer users are identified by questions that ask if the subject uses computers at home, at work, or at school. Internet users are identified by questions that ask if the subject uses the Internet at any location. (Contains 1 table and 3 footnotes.)
