Dual-frame, random-digit-dialing (DFRDD) surveys, using a frame of landline telephone numbers and a frame of cell phone numbers, have become the norm for telephone surveys. Two alternative frame constructions sample exclusively from a cell phone frame, referred to as the ‘single-frame cell,’ and sample from the listed landline frame and the cell phone frame, referred to as ‘listed/cell.’ The listed/cell frame construction differs from the DFRDD in that it does not select unlisted-landline frame members. We observe in our simulated data that the listed/cell frame construction results in estimates that more closely approximate the estimates from DFRDD compared with the single frame cell, results in an improvement in precision compared with the DFRDD that is not as large as the improvement in the single-frame cell, and has lower cost than both the DFRDD and the single-frame cell. We conclude that a listed/cell frame construction might be a better solution than either a DFRDD or single-frame cell frame construction.
