30 DAYS ALIVE This variable counts the number of days between when a coversheet was issued and when the interview was completed. This variable was built from the control file. Since only one disposition (interview, non-interview) was taken from each cluster in a sample week, those cases in the control file where the previous case has the same cluster ID and sample week were REDRAWN coversheets. Days Alive, therefore, is equal to Che "Days of Interviewing" Period for all sheets that WERE NOT REDRAWN. For those coversheets that WERE REDRAWN, Days Alive records the difference between "Days of Interviewing" Period for the record and the previous record. 01. . . . . 26. 99. NA
