derived from the Household Grids and are included on the family background
files and the parental attitudes files corresponding to each wave.
10.1 How to use the Index file
The Index file includes individual level identifiers for the young person, main
parent and the second parent (where applicable) which identify their position
within the Household Grid. The young person is always fixed as person one in
all households and can be identified by selecting on the variable HHID=1.
Both the main and second parent can take any position within the index file
but can be identified for each wave using the variables WxMAINRES (for the
main parent) and WxSECORES (for the second parent). This only applies to
Waves 1 to 4, since from Wave 5 main and second parents were no longer
identified in the interview. Similarly, the history respondent can take any
position within the Index file and can be identified for each wave using the
variables WxHISTRES.
Users who wish to create person specific datasets i.e. with mother only
responses or with second parent only responses can use a combination of the
variables discussed in Sections 8.2.16 to 8.2.19.
The six variables WxHHRESP indicate whether there is information for an
individual household member at a particular wave.
Survey level information is also available relating to Wave 1 to 4, providing
users with an overall indication of response for each respondent (i.e.
main/second parent, young person and history respondent) These variables
are discussed in more detail in Section 10.2.22 onwards and will help users
interested in longitudinal analysis of the data.
