The basic purpose of the elaboration is a presentation of structure of wages and salaries by occupations. Due to differences occurring in classifications, which have been occurred in the time interval of reference, data on a level of wages and salaries in the breakdown of occupational groups were presented separately for the years 2001 – 2002 and 2004 and 2006.
