• The NIHPS is an extension of the British

• achieved sample 1,978 households and 3,458
  individuals
• Household Response 69
• Individual Response 89

• Complete Household Response for all eligible
  individuals 70
• Interviews at Waves 1 and 2 83

• Unique value of the NIHPS
• Follows the same representative sample of
  individuals over a period of years

• Their natural children born after the start of
  the study
• Temporary Sample Members (TSMs) eligible only
  while living with an OSM
• People who form households with OSMs after the
  start of the study

12

• Sample Membership Status
• Permanent Sample Members (PSMs)
• TSMs may become PSMs if they are deemed to have a
  sufficiently strong continuing bond to an OSM to
  justify following them even if they cease to live
  with that person

13

• There are 3 main parts to the NIHPS
• Household Interview Household Reference Person
  (HRP)
