This report provides statistical information on computer use in the United States in 1984, including home, work, and school use, and use according to socioeconomic status, race, and sex. The data show that over 15 million American adults owned home computers, but only 53% actually use them. About 8% of U.S. households, or 6.98 million, had a computer in 1984, and households with school age children were three times more likely to have a computer. Students aged 10 to 13 were the most likely to use a computer at school. Among adults, 63% of the men and 43% of the women used the computer if it was present in the house. Households with incomes of $50,000 or more were the most likely to own a computer (23%), while households with incomes of $10,000 or less were the least likely (2%). Although blacks were less likely to have home computers, black children who did have them used them more than white children. Survey data are presented in three text tables and five detailed tables. Appendixes provide additional tables and information on the survey itself, including its reliability and the survey instrument. (EW)
