Abstract

When there is no sampling frame on the households, area sampling procedure provides a proper sampling frame and allows to sample household units in equal probability. Thus, we can obtain reliable estimates without sampling frame. Despite of these advantages, however, it has been hard for academic or non-academic researchers in Korea to conduct the surveys using area sampling because the list of enumeration districts is not open to the public, except for the samplers working in official statistics. But now area sampling in Korea, where information technology is highly advanced, is viable owing to the development of the Internet that enables researchers to get more precise information on the number of dwellings or structures, there location and address, etc. Based on this information, we can easily and correctly use area sampling procedure. This study shows how to conduct area sampling by using commercial maps, street view service and new address information map service offered on the Internet. We also present how to use the information on small areas available in the website of Statistics Korea. This methodology would lead to obtaining more reliable estimates.
