Abstract:
|
Reluctant respondents and low response rates have resulted in increased data collection costs to maintain the same level of response from one year to the next. Consequently, survey managers must assess the efficient allocation of a fixed budget to achieve the survey objectives when the survey is conducted. The list collection of college graduates is a major component of the NSRCG design and one that has considerable costs associated with it. In particular, data collection resources are concentrated on a small set of late responding schools. These resources could be used elsewhere if the schools responded earlier. This paper focuses on the effect of school nonresponse if the list collection period was not extended and a higher school level nonresponse rate was accepted. With this objective, we assess the bias of survey estimates due to school-level nonresponse at varying response rates.
