NetSmart V was based on a half hour, nationwide, telephone survey of 1000 Internet users who are online at least an hour a week, excluding e-mail.
The survey base was a stratified sample drawn so as to reflect the incidence of users of online services and those who access the Internet and World Wide Web through direct access providers. Selected for the sample were residential telephone numbers of households where someone had indicated usage of online services or direct Internet access.
In the survey, potential respondents were screened to accept only user ages 21 to 65.
Phone interviews were conducted using carefully trained interviewers in a supervised and monitored calling center. The questionnaire was pre-tested with 25 interviews. Each interview averaged 30 minutes in length.
The sample was balanced geographically to reflect all regions of the United States. It was structured to reflect the generally agreed upon statistics of online users.
