Input coding is the process by which certain data items were categorised during the interview. In the 2011-12 NHS and NNPAS, these included:

  • country of birth of respondent and their parents
  • main language spoken at home
  • occupation
  • industry and industry sector
  • educational qualification
  • relationship within a household.

More detail regarding use of these classifications, except relationship in household, is contained in Appendix 3: ABS Standard Classifications.
