Post-stratification or a non-response adjustment?

Abstract

This paper considers the conceptual similarities and differences in weight adjustment steps known as nonresponse adjustment, post-stratification, and calibration. The distinction is based on the information requirements, i.e., whether the data necessary for the specific type of weight adjustment exist at the population level, at the level of the original sample that includes both respondents and nonrespondents, and/or at the respondent level. An illustrative example is provided where the different weights are constructed.
