Abstract:

Unit nonresponse in a household survey may introduce substantial bias into estimates when (i) the number of nonrespondents is large relative to the sample size or (ii) the characteristics of nonrespondents differ greatly from those of respondents. Household surveys expend considerable effort and money to interview reluctant respondents. This additional effort is only worthwhile if it results in a set of respondents that is representative of the target population. In this study, logistic regression models are developed to compare characteristics of early respondents to those interviewed only with great effort. Data collected from the Omnibus Household Survey (OHS), a RDD survey on transportation issues, will be analyzed. In addition, because the sample size of the annual OHS is very small, multiple years of data will be used to augment sample size for this study.
