3. II.- BEST SOURCES AND METHODS ON LABOUR INPUT VOLUMES FOR SPAIN II ISSUES BETWEEN NA & LFS: 1980-1995 NA & LFS use the SAME DEFINITIONS for employed persons and employees (employed persons= selfemployed + employees) In general, NA figures are higher than those from LFS For some sectors this is not the case 1995-2004 DIFFERENT DEFINITIONS: LFS uses employed persons & employees. NA introduces jobs for self employed & employees. Full- time equivalent jobs are also computed (dividing total annual hours worked by the annual average of hours worked in a full-time job). 2000: LFS methodological change: new definition of unemployed, following Eurostat criteria. Many unemployed persons exit the labour force. May 2005: new release of NA 2000-04 (new year base 2000) June 2005: new release of LFS 1996-2004, with a great increase of the # of occupied persons & employees (immigrant population is introduced in the elevation factors through the municipal census)

4. III.- IN CASE YOU PREFER TO DIFFER FROM THE NA, WHY? We consider the NA figures for jobs and full time equivalent jobs (in aggregate for all sectors), as the best choice. We might suggest changes for some specific sectors.
