Effects of rotation groups, interviewing modes and interviewers on the LFS estimates

Doc: 05/2010

This paper examines the influence of three factors (rotation groups, method of interview and interviewer effect) on the main estimations in the Labour Force Survey (LFS), by performing probit and homogeneity analysis. It also shows that the influence of the interview method is partially due to the different representation of foreign people in the CATI and CAPI samples. Finally, it highlights the importance of a correct identification of the bias sources and outlines the future plans to improve the standardization in the Spanish LFS.
