NoteAn important variable for analysis purposes. With a few exceptions, data from proxies have been merged with that from respondents. Proxies and telephone interviewees, however, have zero respondent weights and can be selected out by use of this variable. Additional categories and minor recoding in comparison with Wave One. A coding frame for this variable with full labels can be found in Appendix to Volume A.
