Abstract:
|
Labor force estimates of the U.S. civilian noninstitutional population are derived through a number of weighting steps in the Current Population Survey (CPS) estimation procedure. Currently, the weight for each interviewed person includes a second-stage ratio adjustment. This second-stage estimation process uses Iterative Proportional Fitting (IPF), or raking, in order to simultaneously match three sets of independent population controls and to create second-stage weights. Upon completion of the second-stage process, the weights are subjected to a composite estimation process which also uses a three-way rake to match composite population controls; but the procedure does not reproduce all second-stage controls. This paper explores more complex raking methods to determine if a single set of weights can be produced that simultaneously preserves all second-stage and composite controls.
