Effects of Post-Stratification on the Estimates of the Finnish Labour Force Survey
Abstract:In Finland, two competing unemployment statistics are published monthly. Their estimates differ from each other in a very systematic manner: the Labour Force Survey (LFS) estimates are lower than the register counts. This article examines the estimation procedures used in the LFS. We focus on the effects of the present post-stratification procedure. In addition, we investigate the possibility of obtaining more precise estimates by using auxiliary information derived from registers. As a result, we suggest that the present estimation procedure be replaced by the incomplete post-stratification (or generalized raking) method.
Keywords:Post-stratification; generalized raking estimation; auxiliary information; nonresponse bias.
