Abstract

Response rates in national household surveys conducted by Statistics Korea have declined over the past years. This is particularly true of the Korean Labor Force Survey (KLFS), which is one of the major surveys. The purpose of this study is to construct a hard-to-survey index (HTSI) to be useful in investigating sampling units such as the enumeration districts (EDs) where response rates in the KLFS tend to be lower than others. To build the HTSI, we first define the underlying constructs to measure how difficult to survey a sampling unit, and then we compute the scores based on regression models depending on the significant variables related to the constructs. The scores are served as the HTSI and the EDs with high scores are designated as hard-to-survey areas. We examine the performance of the HTSI by analyzing correlations with some indicators of nonresponse.
