Abstract

When there is no available list sample frame, area probability sampling enables researchers to select samples and obtain reliable estimates for household populations. However, a considerable amount of time and cost is associated with on-site enumeration, precluding it from being a viable approach in building sampling frames for many household surveys. Area sampling using information technology (IT) may be an alternative for saving time and effort. In this paper, we present a new methodology for constructing household sampling frames based on the existing Internet information services in a metropolitan survey, which was conducted to investigate health problems among residents from communities surrounding industrial complexes in Korea. This method uses highly advanced IT including mailing address information and map service. It is also useful in cases where the list of enumeration districts is not open to the public, like in Korea. Since there is no limitation in the size of areas as well as the number of dwellings in the survey population, this approach would apply to national surveys. Some survey results are provided.
