The "Pew" Internet and American Life: Daily Tracking Survey (March thru June 2000)

This data set contains four months of Pew's daily tracking survey on Americans' use of the Internet. This data set consists 10,642 interviews completed March through June 2000. All surveys were done over the phone and the interviewing was conducted by the Princeton Survey Research Associates between March 1, 2000 and June 30, 2000. Each month was an independent random sample and the questionnaires differ from month to month. The data set includes a variable called month, which allows you to do separate analysis by month of interview.

Non-response in telephone interview surveys produces some known biases in survey-derived estimates because participation tends to vary for different subgroups of the population, and these subgroups are likely to vary also on questions of substantive interest. In order to compensate for these known biases, the dataset includes a variable named 'weight' to adjust the biases. This weight incorporates adjustments for differential probabilities of selection, for non-response, and for post-stratification. The demographic weighting parameters were derived from a special analysis of the Census Bureau's Current Population Survey (March 1999). When using the data set weight the sample size increases to 21,486.
