This also includes benefits, premiums and payments in kind, if the calculation of these payments is not based on the time actually worked. Nonprofit organisztions with less than 50 employees are excluded from the survey. The average monthly gross wages and salaries excludes payments to employees with a contract of agreement because it is difficult to measure the working time of those employees, and the Estonian laws do not require it to be measured. Thus it is difficult to convert the working time of those employees into full time equivalents. A special survey on occupations and sex is carried out in October.
Reference period is a quarter by economic activity.
The population of a survey consists of all economically active units. The register of economically active units is based on the Estonian Enterprise Register. The register of economically active units is updated every year. From the remaining part of the population, i.e. from enterprises with less than 20 employees, a stratified simple random sample was selected. Nonprofit organizations were excluded from the survey.
