Notes
This question was introduced part way through fieldwork in April 2009.
ACE touchscreen question "How many OLDER brothers/sisters do you have? (Please include those who have died, and twins. Do not include half-, step- or adopted brothers and sisters)"
The following checks were performed:
- If answer < 0 then rejected
- If answer > 25 then rejected
- If answer > 10 then participant asked to confirm
Field 5057 was collected from participants except those who indicated they were adopted as a child, as defined by their answers to Field 1767
Coding 100291 defines 2 special values:
- -1 represents "Do not know"
- -3 represents "Prefer not to answer"
