Definition:
The importance of an object in relation to a set of objects to which it belongs; a numerical coefficient attached to an observation, frequently by multiplication, in order that it shall assume a desired degree of importance in a function of all the observations of the set.

Context:
Reweighting consists of raising the original weights for the respondent values when estimates are computed. Reweighting concerns mainly unit non-response. It may also be used to increase precision through the use of auxiliary information. Standard methods include post-stratification, calibration and response propensity modelling (Eurostat, “Assessment of Quality in Statistics: Glossary”, Working Group, Luxembourg, October 2003).
