Appendix B: Detailed Methology AARP Multicultural Survey

Response and Refusal Rates Formulae

We use AAPOR Response Rate 5 (RR5) to calculate response rates for each of the samples and Refusal Rate 3 (REF3) to determine their refusal rates. RR5 and REF3 treat the eligibility estimate of the numbers with unknown statuses (UH) as zero, essentially eliminating them from the rate calculations.

____________________

*All partial interviews are counted as break-offs (mid-interview termination) and classified as refusals.

**Non-contacts are cases in which the RDD number is confirmed as reaching a residential housing unit (household with adult 18+ years of age) but the selected respondent is never available, including housing units where answering devices confirm the existence of a residence but it was not possible to determine an eligible household (45-55 year olds present).

***Other are cases not falling in eligible categories where a potential respondent is supposedly available but no interview takes place, most often for this study due to a language barrier, so even eligibility can not be determined.

**** Telephone numbers that were always busy, or that rang with no answer every time they were tried.
