Cross-Study ID File 1972, 1974, 1976

This file provides case ID information across the following studies by respondent:

• NES 1972 time series (cross-section) Study
• NES 1974 time series (cross-section) Study
• NES 1976 time series (cross-section) Study
• NES 1972-1974-1976 Series File

The 1972-1974-1976 Series File includes cases from the following:

• 1972 time series (cross-section) Study
• 1974 time series (cross-section) Study
• 1976 time series (cross-section) Study *
• 1972-1974 Panel
• 1974-1976 Panel
• 1972-1974-1976 Panel

Variables TS72ID, TS74ID, TS76ID are case IDs represented in the individual time series studies 1972, 1974 and 1976 respectively. Variables SERIES72, SERIES74, and SERIES76 are IDs from the Series File and represent all cases 1972, 1974 and 1976 released as part of that dataset.

Participation can be tracked across studies. Variable PAN72_74 is flagged 1 for all cases included in the 1972-1974 Panel (0 otherwise), variable PAN74_76 is flagged 1 for all cases included in the 1974-1976 Panel (0 otherwise), and variable PAN72_76 is flagged 1 for all cases in the 1972-1974-1976 Panel (0 otherwise). Variables CROSS72, CROSS74, CROSS76 are flagged 1 if a case is represented (respectively) in the 1972, 1974, or 1976 cross-section (time series) study. Participation by wave may also be tracked using variables PRE72, POST72, POST74, PRE76 and POST76, which are coded 1 if R was interviwed in that wave (0 if not).

The ID File is a tab-delimited ASCII text file with variable labels in row 1.

* NOTE: the 1976 time series dataset includes 1 case which is not included in the series file; it is represented in the ID file.
