Structure of the Data Files

For each wave, there are four files:

• Household File – containing information from the HF and HQ.
• Enumerated Person File – listing all persons in all responding households and contains limited information from the HF (includes respondents, non-respondents and children).
• Responding Person File – containing all persons who provided an interview and contains CPQ/NPQ and SCQ information.
• Combined file – this is a combined file of the three files above. The household information and responding person information is matched to each enumerated person.

In addition, a master file and a longitudinal weights file are provided with the files for the most recent wave (for Release 6.0, this is wave 6). The master file contains all persons enumerated at any wave, their interview status in each wave and limited information about the individual. The longitudinal weights file contains weights for all sequential balanced panel combinations and all balanced pairs of waves.
