• Employees are persons at age 13 or above, who in the relevant month received a wage of minimum 4 hours a month through the pay-as-you-earn (PAYE) tax system. 
• Persons that are temporary absent form work are also included whether they receive wages or not (such as shift work, flex time, compensatory leave for overtime, parental leave or illness).
• Region refers to the employee's region of residence

Other definitions: 

• Employees (main job): Main job of an employee is set to be the main activity and institutional sector of the employer from which the largest wage is received. An employee only counts once.
• Main- and minor jobs: Counts the total of main- and minor jobs together in the institutional sector/economic activity. An employee can have multiple counts due to several jobs in each institutional sector/economic activity.
• Minor jobs: Counts the number of minor jobs in the institutional sector/economic activity. An employee can have multiple counts. Main jobs are excluded.
• Jobs across economic activities: This value portrays the number of employees in each institutional sector/main activity when minor jobs are also included. An employee can only count once in each institutional sector/economic activity, but several times across. Thus the number is higher than the measure of number of employees (main job).
• Employers: Counts the number of employers. Employers count only once, which is in their main activity.”
• Institutional sector: The sorting of institutional entities by economic activity. The economic activity is determined by whether the goods and services produced are for the market, whether the ownership is public or private, as well as the type of production. The definitions and terms used are based on the guidelines provided in the 'System of National Accounts' (SNA) by the United Nations and the 'European System of Accounts' (ESA) by Eurostat. In the wage and employment statistics the institutional sectors are grouped differently than normal. Non-financial corporations, financial corporations, households and organizations are grouped together and divided by whether the ownership is public, private or foreign. Public administration and services is unchanged and is divided in to central government, state government, local government and social security funds. 'The Rest of the World' is a separate institutional sector, which is grouped together with unknown sector, if any. When the employment statistics are depicted and described, the institutional sector is often divided by whether the employers are under public or private control.
  • "Under public control" includes "General government" + "Public corporations" 
  • "Under private control" includes "National Private corporations" + "Foreign controlled corporations" + "Rest of the world and not specified"  
• Main activity: Main activity is attached to the employer that pays the wage. An employer is grouped in to the main activity in which he has the largest activity. A person may have several employers, and the employer from which the most wage is paid is set to be the person's main activity of work. Main activity is not necessarily the actual economic activity of the work done for the wages paid as an employer may cover several economic activities. Main activity is based on the international statistical classification of economic activities NACE rev. 2. The first and second level are directly comparable. The third level opens up a few subgroups in order to best portray the national economy. On the third level there are 93 economic activities.
