"Each year the quarterly employee jobs figures are benchmarked to the ABI annual inquiry, and at the same time the annual seasonal adjustment review is incorporated. This year, ONS is also carrying through the implications of the 2001 Census population data to the estimates of workforce jobs. This article describes each of the type of revisions that ONS has taken on, and provides an indication of their impact on the total workforce jobs estimates. It also provides an up-to-date comparison of the population-based Labour Force Survey (LFS) employment estimates and the business-based workforce jobs estimates.The main effects of these various revisions has been to raise the number of employee jobs in December 2001 by 153,000 and revise downwards self-employed jobs. Comparisons between the revised workforce jobs series and the post-2001 Census LFS jobs series show a substantial gap between the two series."
