The purpose of this report is to examine the consistency and reliability of the activity history data collected in the FACS. Using data from the first five waves of the FACS and from the first thirteen waves of the British Household Panel Survey (BHPS) as a comparison survey, carefully matched samples have been analysed to calibrate the completeness and consistency of the activity history data collected in the FACS and to test whether the FACS generates labour market statistics similar to the comparison survey.
