Abstract:

Household frames in area probability samples have traditionally been constructed by sending trained field staff to construct these lists on location. The cost of doing so often constitutes a sizable portion of the field operation budgets. This paper investigates an alternative solution to the household frame construction task using GIS and GPS technology applied to property tax files, which are increasing found to be available in GIS format through local tax offices. We present findings from an field comparison study in Central North Carolina involving the GIS-based approach and the traditional household listing approach, using both cost and frame coverage evaluation criteria. We find that the GIS-based approach is less costly, has comparable sample coverage outcomes, and provide locator information that is easy and effective to use.
