WEIGHTS AND IMPUTATIONS IN SHARE WAVE 9

This chapter describes the weighting and imputation strategies used for dealing with problems of unit nonresponse, sample attrition, and item nonresponse in the most recent SHARE studies: the ninth regular wave of SHARE and the second wave of the SHARE Corona Survey. The remainder of the chapter is organized as follows. Section 8.2 provides a brief overview of the key features of these two studies that are relevant for the purposes of our weights and imputation strategies. Section 8.3 focuses on the construction of calibrated survey weights that attempt to compensate for the potential selection effects generated by unit nonresponse and attrition, while Section 8.4 focuses on the construction of (multiple) imputations for the missing values due to item nonresponse errors.
