Current Dataset Release: 2016-May-04 version
2018-May-22 A new variable has been made available to indicate whether respondent members of the KnowledgePanel (i.e., respondents who completed the study on the Internet) did or did not receive a laptop computer to enable their participation in the KnowledgePanel. The "laptop" variable is coded 0 if the respondent did not receive a device and is coded 1 if the respondent did receive a device. These data are available in SPSS and .csv format and can be merged with the main dataset using the caseID variable. The file does not include entries for the cases in the face-to-face sample, for whom this variable is not applicable.
Laptop variable for Internet cases: SAV zip    |    CSV zip
