Abstract

As an integral part of the PRCES, the PRTPOPS was done in Puerto Rico. The USBLS collaborated with the PRBLS with technical assistance and in the construction of the instruments. A CATI System was used and the AAPOR standards for final classification were enforced. The time period for follow-up calls was blocked. An electronic list of all listed residential telephone numbers, as of April 20, 2001, and the prevalence of unlisted numbers in 100-numbers non zero clusters, or "unlisted clusters," were provided by the PRTC. This was a first-time approach to increase frame efficiency and reduce implementation complexities in the PR telephone surveys. A pps cluster sample was selected from unlisted clusters with, at least both, 15 % hit rate and 10 unlisted numbers; systematic sampling was used in the listed numbers frame. Six pseudo replicates (waves) per POPS Group were selected during a six-month period, stratified by family income and geographic region, resulting in 44,603 initial calls and 8,524 final interviews.
