Viera Jr. 1 , S. Turner 2 , S. Marsh 1 , R. Medway 31 Fors Marsh Group, United States; 2 Fors Marsh Group LLC, United States; 3 Joint Program in Survey Methodology,University of Maryland, United StatesResearchers in the industry are quickly coming to the realizaon that nonresponse bias in esmates is onlyindirectly related to nonresponse rates. The general statement that ”the lower your response rate, the morevulnerable your study is to nonresponse bias” has been proven a gross oversimplificaon. Because even veryhigh response rates have the potenal for very high bias on specific esmates within a survey, recent calls formore nonresponse bias studies have been made (Groves, 2006). However, conducng such analyses in manylarge, naonal surveys is oen problemac when limited informaon about nonrespondents is available on thesurvey frame. Therefore, researchers have sought to find new ways of conducng nonresponse bias analysesby appending auxiliary data to their samples...3.2.2 Assessment of propensity score methods on nonresponse bias adjustmentA.
