Note: Getting an accurate picture of the distribution of computer and network use among U.S. citizens is not straightforward. Numerous samples are used to generate publicized survey data, but close examination shows that despite care in the planning of sample design, the actual data must be adjusted statistically (through the use of weights) to achieve meaningful and accurate inferences about the U.S. population. In addition, what is being measured is often neither clear nor consistent. Survey researchers have observed, for example, that people often do not understand enough about their equipment or services to answer questions reliably; questions about activities and uses tend to yield more accurate and consistent results. Another factor inspiring caution about reported data is that there is significant "churn" in the PC application and services markets: people start and stop activity relatively often, but it is too soon to describe either long-term attrition rates or consistent patterns in how use varies over time and among different categories of people.
