The workforce jobs series are revised in December each year.
The workforce jobs series include estimates for employees, self-employed, HM Forces and government-supported trainees. It supplements the main estimates of employment from the Labour Force Survey (LFS).
Employee jobs are benchmarked annually to the results of the Annual Business Inquiry (ABI). Figures on self-employment jobs from the LFS have also been revised.
The results of the short term-employment surveys released in December 2004 have, for most industrial sectors, been benchmarked to the ABI for December 2003, as usual taking on board any revisions for the previous year. The exceptions are industrial sectors F (construction), part of I (national post activities), L (public administration and defence), M (education) and N (health and social work), where the results of the most recent ABIs are still being checked against alternative sources.
Revisions to Northern Ireland data take into account the revised editing procedures used in the Labour Force Survey.
