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 nonresponse. It may also be used to increase precision through the use of auxiliary information. Standard methods include poststratification, calibration and response propensity modelling (Eurostat, “Assessment of Quality in Statistics: Glossary”, Working Group, Luxembourg, October 2003).
