STUDY DESIGN HIGHLIGHTS:
In each year 1972, 1974, and 1976, respondents could be defined as 'panel-only,' 'Time Series only' or 'both panel and Time Series.' Members of the last group were counted in the cross-section of the year's Time Series study and were also counted within one or more of the panels. The yearly status of interview cases as panel, cross-section, or both is as follows:
'Panel and Time Series' cases intersect membership as follows.
* in the 1972-1976 Merged File, there are 2,259 cases identified as 1976 cross-section; 11 of these
For the panels, attempts were made to follow movers who still lived within 50 miles of a sample area. In 1974, panel reinterviews were sought with all respondents who had been interviewed in both waves of the 1972 Time Series study; in 1976, panel reinterviews were sought with existing panel members and with the new cross-section cases from the 1974 study.
1972-1974-1976 panel respondents are 1972 Time Series cross-section respondents who were interviewed twice (pre and post) in 1972 and then successfully re-interviewed in 1974 and in at least 1 wave in 1976; also among the cases defined for this panel are 24 cases of 1972 pre-and-post respondents who were re-interviewed in 1976 (both pre and Post) even though they had not been re-interviewed in 1974. 1972-1974 panel respondents are 1972 Time Series cross-section respondents who were interviewed in both 1972 waves and then re-interviewed in 1974, regardless whether they were ever re-interviewed in 1976. 1974-1976 panel respondents are 1974 cross-section respondents who were re-interviewed at least once in 1976 (pre or post). The 1974-1976 panel includes respondents not present in either of the other panels because the 1974 cross-section incorporated new respondents as well as respondents who had already participated in the 1972 Time Series study.
Samples for the the 1972-1974-1976 panel, the 1972-1974 panel, and the 1972 Time Series study are unweighted; a sample selection variable is present for each (V764002, V764003 and V764005, respectively).
For the 1974-1976 panel, weight/sample selection variable V764004 selects cases from this panel and also weights to compensate for the differential sampling rates used in 1974 and 1976 for the different sample components.
