Within each household, one individual aged 25+ was selected based on specific instructions within the letter they received (or provided by the interviewer if they responded by phone). The instructions used the age of household members to determine who was selected, and varied from one household to another. For some households, the oldest member was selected, others the second oldest, or the youngest, etc. These letters were randomly assigned to the selected dwellings ensuring that the selected individual from within the dwelling was random.
