Our survey statistics expert Stas Kolenikov (Ph.D., PStat) offers practical advice and clarification
on the weighting procedures in his recently published Survey Practice article “Is It a Post-
Stratification or a Non-Response Adjustment?”
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.
