Abstract

This paper presents a dynamic dual-frame sampling approach for a national survey that selects monthly samples independently for each of the 50 US states and the District of Columbia. Each state has a separate allocation to the cell and landline telephone samples that reflects the estimated share of the cell-only and cell-mostly segments. The survey excludes the overlap set of cell numbers that also have landline access. The design also oversamples listed households in the landline sample, and a subset of cell numbers flagged as active via Marketing Systems Group's Cell-WINS service. We examine the gains on productivity resulting from the oversampling in both frames.
