In compliance with the European Union Council Regulation No 530/1999 and Commission Regulation (EC) No 1738/2005 the Structure of Earnings Survey is conducted once in four years. Data acquired within the survey are used to obtain detailed information on number of employees and wages in breakdown by occupation, sex, age, educational attainment, number of years worked for the enterprises on country as a whole as well as by economic activity or region, in 2010 totally and selected indicators on October. Survey compiles information on number of employees having collective agreement.


Gross wages and salaries – wages and salaries calculated on all months of 2010, including wage tax and statutory social security contributions payable by employees.

It includes regular and irregular payments: basic salary (monthly salary, wage), payments on time worked or amount of work done, regular and irregular bonuses and premiums, payment for annual leave and additional annual leave, additional payment before vocation, leave benefit, compensation for unused leave, payments of sick list A, payments of holidays and other days not worked, statutory social security contributions payable by employees, and sums of income tax.

It is one twelfth of annual gross wages and salaries.

Gross wages and salaries (regular costs) on average per hour in October are calculated by dividing employee calculated gross wage and salary regular payments in October by sum of hours worked and paid in October.

Within the framework of this survey employee is natural person, which on the basis of labour contract or contractor agreement for agreed wage or salary performs certain job, for which according to the Labour Law the working time is registered, or working time registration is made according to the contractor agreement.

It includes only regular costs on October and does not include all irregular payments to employees, i.e., not regularly calculated every month: bonuses and premiums paid for certain time periods not regularly every month, bonuses related to individually or collectively performed work (e.g., irregular bonuses – quarterly, half-year and for longer time period, holiday bonuses; 13th and 14th salary), payment for additional annual leave, additional payment before vocation, leave benefit, compensation for unused leave.

Statistical unit or part thereof (e.g., workshop, shop, studio, factory, store, warehouse, office, mine or storehouse) where economic activity is performed and that is located in place geographically identified by postal address.

Structure of Earnings Survey data are compiled and calculated by using:

  • Classification of Occupations of the Republic of Latvia, based on the International Standard Classification of Occupations (ISCO-08);
  • Statistical Classification of Economic Activities (NACE Rev. 2);
  • Classification of Administrative Territories and Territorial Units of the Republic of Latvia (CATTU);
  • Nomenclature of Territorial Units for Statistics (NUTS);
  • Educational Classification of Latvia;
  • International Standard Classification of Education (ISCED).

A Classification Catalogue with classification codes and their explanations has been published on the CSB website.

Data collection

Survey method and source data

Data on structure of earnings are obtained by conducting sample survey, collecting information with the help of the CSB questionnaire "Report on structure of wages and salaries in 2010" (5-Labour).

Survey sample was stratified two-stage random sample. For the stratification of local units three features were used: kind of economic activity, number of employees and region. Sample size in each stratum was determined with the help of combined Neuman optimum placement, considering the number of local units in stratum and number of employees of the corresponding stratum. In the first sample stage local units in each stratum were selected with the help of simple random sampling.

In second stage of the sample statistical units selected employees on which information had to be submitted, considering following rules:

  • if in local unit there were 1–50 employees, information had to be submitted on all employees,
  • if there were 51–69 employees – on 50 employees,
  • if 70–149 – on 60,
  • if 150–249 – on 70,
  • if 250–499 – on 80,
  • if 500–999 – on 90,
  • if 1 000 and more – on 8% of the total number of employees in the local unit on October 31, 2010.

Statistical unit was allowed to provide information on all local unit employees if it was more convenient.

In survey it was considered that, there are no local units in the statistical units employing less than 50 persons, except financial and insurance sector (NACE Rev. 2 code 64, 65 and 66 of Section K), where it was assumed that, there are no local units in the statistical units employing less than 10 persons.

Centralised accountancies of budgetary institutions submitted data not on local units, but on seven activities electricity, gas, steam and air conditioning supply (NACE Rev. 2 code 35), public administration and defence; compulsory social security (NACE Rev. 2 Code 84), education (85), residential care activities (87), social work activities without accommodation (88), creative, arts and entertainment activities (90), and libraries, archives, museums and other cultural activities (91). It was assumed that, one kind of activity is one local unit. Such collection of information does not cause mistakes in the data of earnings structure survey in breakdown by region, because local units of local governments always are located in the territory of local government.

Number of employees indicated in report of each local unit was extrapolated on all employees of the local unit with the help of weight coefficients.

Summaries were based on following additional activities:

  • employees for which wage or salary in October was calculated under average earnings (sick-leave certificate A) were excluded from the sample, and weights for other employees were increased;
  • selected employees, who during a year or in October worked less than one month, were excluded from the sample, and weights for the other employees were increased;
  • for employees having unpaid days or less days worked in October due to recruitment, October wage and hours paid were re-calculated for whole (full) month.

Statistical population

All commercial companies, individual merchants, peasant and fishermen farms (with 50 and more employees), budgetary institutions, foundations, associations and funds, which were economically active on October 31, 2010. Survey includes both full-time and part-time employees, which on October 31, 2010 were employed in main or secondary job and received wages or salaries.

Survey does not include employees, which had labour contract on performance of urgent, short-term or single jobs – not more than 43 hours per month or 10 hours per week, and those employees having labour or collective agreement according to which it was not possible to determine hours actually worked, as well as self-employed, which pay social security contributions themselves.

Survey does not include also following persons:

  • employers – persons having business or professional practice and who are employing one or several other persons, but do not receive wage or salary (their income consist of part of the profit);
  • self employed – persons working in own business or professional practice with an aim to earn income and do not employ other persons;
  • employed family (household) members of the respondent for which wages or salaries are not calculated.

Survey did not cover also employees of military occupations.

Sample size

Thus sample included 18 thousand local units or approximately 10 thousand respondents. Totally sample covered 229.1 thousand employees.

Calculation methods

As a two-stage sample was used in the survey, in order to obtain summary data, two weights are calculated for each employee included in the sample. Firstly, weights, when local unit is extrapolated on all local units (Svv), and, secondly, weights extrapolating employee on all employees of the local unit (Sdarb).

Firstly monthly average gross annual wage (DSvid) of each employee is calculated, considering workload and number of months worked.

DSvid = calculated gross annual wage / (workload * number of months for which wage was calculated).

To estimate sum of monthly average gross wages, calculated DSvid on each employee is multiplied by both weights – Svv and Sdarb. To determine number of employees receiving such wage, the products of both weights is summed.

As a result formula for the calculation of monthly average gross annual wage is following:
Σ (DSvid * Svv * Sdarb) / Σ (Svv * Sdarb)

Monthly average gross wage in October (DSokt) includes only regular payments and it is calculated as follows:

DSokt = Σ ((regular payments of calculated gross wage in October / workload) * Svv * Sdarb) / Σ (Svv * Sdarb).
DSSTokt. = Σ ((regular payments of calculated gross wage in October * Svv * Sdarb) / Σ (number of hours paid * Svv * Sdarb)

Average hourly gross wage in October (DSSTokt) includes only regular payments and it is calculated as follows:

DSSTokt. = Σ ((regular payments of calculated gross wage in October * Svv * Sdarb) / Σ (number of hours paid * Svv * Sdarb)

To estimate number of employees by specific characteristics (age, educational attainment, etc.), both stage weight product of selected employees are summed.

Data revision

Data are final and will not be revised.

In some cases, due to specifics of electronic data processing technologies and rounding adjustments, slight discrepancies may occur between totals and sums of components.


Comparability over time

Structure of earnings data are comparable with the data from the survey of 2006.

International comparability


The Statistical Office of the European Union (Eurostat) compiles and on own webpage publishes information on structure of wages and salaries in EU and on each country separately.
