of Respondent Within Household
The multi-stage sampling
process described in the previous sections yielded a random national sample
of households with telephones, drawn proportionate to the population distribution.
The final stage required the selection of one respondent per household
for the interview.
A systematic selection
procedure was used to select one designated respondent for each household
sampled. The "most recent/next birthday method" was used for within household
selection among multiple eligibles. The Within Household Selection Procedure
is presented in Figure 1. The CATI system alternated the "most recent"
and "next" birthday specification for the selected respondent to avoid
a temporal bias for birthdays before (or after) the field period.
