GENERAL  NOTE: 
Ns indicated below are unweighted. The combined sample of panel and 
fresh-cross cases together constitute an overall representative cross-
section for the time-series study.  Panel cases in 1958,1960,1974 and
1976 are not flagged in the data of the respective time-series studies;
for these years this variable has been coded from the 1956-1958-1960
and 1972-1974-1976 merged panel files.
1958 NOTE:
Panel cases had previously been interviewed in 1956 (note: the number
of panel caes in the 1958 time-series data file does not correspond with
the number of 1958 panel cases in the 1956-1958-1960 merged panel file)
1960 NOTE:
Panel cases had previously been interviewed in 1956 or 1958 (note: the

merged panel file)
1974 NOTE:
Panel cases had previously been interviewed in 1972 (note: the number
of panel caes in the 1974 time-series data file does not correspond with
the number of 1974 panel cases in the 1972-1974-1976 merged panel file)
1976 NOTE:
Panel cases had previously been interviewed in 1972 or 1974 (note: the 
number of panel caes in the 1975 time-series data file does not

merged panel file)
