Contracted man-years are calculated as all employees in the reference week, with part-time employees converted to full-time equivalents. The figures are sourced from the A-ordningen (a coordinated reporting scheme). The percentage is calculated by dividing the agreed man-years within a service area by the total agreed man-years, and multiplying by one hundred. Definitions of what is included in each service area can be found in the explanatory notes for the variable "Function".
