NOTES:
------
1992 NOTE: 
A shorter questionnaire was designed for telephone interviewing only, 
where telephone administration was intended for selected Panel cases; 
all long-form questionnaires were designed to be administered in 
person.  However, due to interviewer misunderstanding, 125 Pre 
interviews and 284 Post interviews -- including both Panel and new 
Cross-Section respondents --were administered over the telephone using 
long-form questionnaires.  Mode of interview here thus cannot be 
identified with short or long questionnaire (VCF0015a,VCF0015b).  [Note: 
additionally, in 1 Pre case a Panel short-form interview was conducted 
in person.]
1998 NOTE:
This is the beginning mode of the interview; in some cases, the 
interview may have been suspended and completed in a different mode.
2000 NOTE: 
Code 1 includes 5 cases which were personal in the Pre and intended to 
be switched to phone mode in the Post, but which were again 
administered face-to-face.
