Notes
ACE touchscreen question "How many years have you lived at your current address?"
The following checks were performed:
- If answer < 1 then rejected
- If answer > Participants age then rejected
If the participant activated the Help button they were shown the message:
If you have lived there for less than one year select Less than a year.
If you are unsure, please provide an estimate or select Do not know.
If you have lived at your current address at different times, add up
the total number of years you lived there. For instance if you lived
at your current address for 3 years, moved overseas for one year and
returned to your current address for another 5 years, then you would
enter 8 years.
