3.1  Data description

The variables collected in monthly and quarterly survey:

A. Number of employees.

B. Wages and salaries.

C. Hours worked.

On the base of above mentioned information the estimation of number of persons employed is realised.

3.2  Classification system

Odvetvová klasifikácia ekonomických cinností (SK NACE Rev. 2) - Branch classification of economic activities – NACE rev.2.

Klasifikácia štatistických územných jednotiek- Nomenclature of Territorial Units for Statistics– NUTS 2010.

Štatistická klasifikácia produktov podľa činností - Classification of products by activity -  CPA 2015.

Enterprises with principal activity in Divisions 05 to 39 of SK NACE Rev. 2 and selected enterprises with a non-industrial principal activity.


3.3  Sector coverage

Enterprises with principal activity in Divisions 05 to 39 of SK NACE Rev. 2 and selected enterprises with a non-industrial principal activity.

All enterprises with 20 and more employees registered in the business register.

In addition enterprises in the business register with less than 20 employees that:

- Are statistically important according to expert judgement;

- Or have a turnover in excess of 5 million Eur.

In addition there are estimates of small enterprises based on quarterly sample survey and sole proprietors performing their business activity on the base of issued trade licences according to Act no. 455/1991 [Digest] (the data source is the number of issued trade licences).
3.4  Statistical concepts and definitions

A.The number of persons employed variable includes:

- Paid employees, e.g. those persons who have a contract of employment and who are on the payroll of the enterprise. Paid working proprietors, paid students and homeworkers, part-time workers, seasonal workers persons on short-term leave are included in the variable. It is measured as an average number;

- Unpaid persons employed, e. g. unpaid working proprietors (owners), unpaid family workers. The data for the unpaid working proprietors is estimated using the data from the structural business statistics survey. 

B.Wages and salaries include the total remuneration of employees counted on the payroll in return for their work, before deduction of their share of social security charges. It includes gratuities and bonuses paid from the profit of the enterprise, payments for emergency work. The particular items are based on the company accounting headings.

C. Average gross nominal monthly wage consists of basic (tariff) wages set by wage rules including basic components of contracted wage and salaries for working overtime, compensation of wage for hours not worked, monthly and long-term bonuses paid according to performance and evaluation criteria, extra payments for working overtime, night work, work during Saturdays and Sundays, holidays, for environment damaging health, noise, risky and hard work, in-kind wages expressed in financial terms and other wages in the form of wage advantages whose level and periodicity are set in advance regardless of the situation in an enterprise.

D. Hours worked include all hours which have actually been worked during the current period (basic or normal hours, overtime hours, hours worked during nights, Sundays or public holidays, short periods of rest at the place of work including tea and coffee breaks, time spent on business trips). The variable excludes hours which are paid but not worked such as paid annual holidays, public holidays, sick leave, or due to accidents, strikes, lock-outs or slack time.

Estimates of this variable are realised for population of small enterprises based on quarterly sample surveys and for self-employed performing their business activity on the base of issued trade licences according to Act no. 455/1991 [Digest] (the data source is the number of issued trade licences). 

The Business register is the frame for identifying units for the population. The Business register is updated in daily frequency from: the business register, the trades register, the professional chambers, and from other ministries. The Business register is updated with information from the tax register, the social insurance company register and from statistical surveys.

12.1  User needs

Description of users and their respective needs with respect to the statistical data.

Consultations with users are required by statistical act stressing the cooperation with other organisations (ministries and other state organisations) during preparation of the Programme of State Statistical Surveys.

An advisory body the Statistical Council consists of members representing main users (representatives of ministries, state organisation and public institutions).

The Council is the permanent expert advisory body for the President of the SOSR in the field of state statistics. The task of the Council is to draft /submit proposals and recommendations regarding state statistics concepts, to discuss the Programme of the state statistical surveys and other tasks according to the Status on the Statistical Council.

In practice the consultations with users run on bilateral bases as well as within activities covered by the action programme Activities focussing on learning about expectation of key users and on supporting better interpretation and better use of statistical products.

Users are consulted:

- In accordance with internal directives on Value adding processes, part Communication with users;

- Via Survey on satisfaction of users with products and services of the SO SR, in two-year periodicity;

Evaluation of the user satisfaction survey also includes satisfactions rate (overall and for specified areas as well as for groups of products) and it is submitted together with conclusions and suggestions for improvements to top management meeting for approval.

12.3  Completeness

100%.


13  Accuracy and reliabilityUp
13.1  Overall accuracy

The return on the exhaustive survey for enterprises with 20 or more employees, which have a significant share in the industry, is more than 95%, so the overall accuracy of industry statistics is very good.
The Statistical Office of the Slovak Republic makes great efforts to prevent the occurrence of errors in the data, for example in the form of inspections, and performs thorough verification of data to detect errors.


13.2  Sampling error

Sampling errors are negligible.The deviation is not measured.


13.3  Non-sampling error

For each survey the Technical project (TP) of data processing is elaborated. One part of TP is dedicated to the description/definitions of checks.

Response rate is the same at the time data are provided to Eurostat and also at the time data are first published nationally

Response rate (October 2017):

  1. At the time data are provided to Eurostat:                  97,83 %
  2. At the time data are first published nationally:            97,83 % 
Response rate is followed-up  by regional statistical Office each day. 
14  Timeliness and punctualityUp
14.1  Timeliness

For the indicator Number of persons employed, Wages and salaries and working hours there are no differencies in timeliness between the different aggregation levels (Total, MIGs, special aggregates, NACE Sections, Divisions, Groups or Classes, if relevant).

Data are released approximately T+43 days after reference month. See details in next point.
14.2  Punctuality

All deadlines have been respected.

15  Coherence and comparabilityUp
15.1  Comparability - geographical

Number of persons employed, wages and salaries and working hours  data are  calculated for all territory of Slovak Republik, sections B,C,D,E, MIGs, special industrial branches, size groups of enterprises by number of persons employed and also divided to regions.


15.2  Comparability - over time

Data is comparable over time.


15.3  Coherence - cross domain

The following data comparison analysis is done:

1)  Comparison of monthly survey results with quarterly data surveyed for the purposes of national accounts (for the calculation of  quarterly GDP);

2)  Comparison with structural business statistics data;

3)  A regular analysis and discussion of the STS experts with the national accounts experts is organised;

4)  The trends of the STS data are compared with the business tendency surveys.

The analysis shows very good compliance level in case of parts of population surveyed exhaustively. Some differences appear when comparing data from monthly, quarterly and yearly samples, which are the subject of further detailed data analysis.


15.4  Coherence - internal

There are no problems with internal consistency in case of Number of persons employed. 

17  Data revisionUp
17.1  Data revision - policy

Revisions are in conformity with standards, time-tested and transparent. They are described in decision ROZ-3/2018 Revision Policy of the SOSR.

The same revision policy is applied to STS data released nationally and transmitted to Eurostat.

According to Revision Policy of the SO SR the revised data are accompanied by all necessary explanations (reasons, character, etc.), they are accessible via the SOSR Portal.

The Revision Policy and Calendar of Revisions of the SOSR as well as all necessary explanations are accessible via the SOSR Portal. 

The Revision Policy of the SO SR

We distinguish:

Routine revisions – regular revisions of data not influenced by change of methodology. In general, the monthly/quarterly data is considered to be preliminary.

Routine revisions of data may be necessary due to data available from quarterly enterprise surveys, new data received from reporting units, correction of price indices or corrected data from reporting units. The revised data for the last 3 months of the quarter are published together with the preliminary results of the following month/quarter. The publication of the revised data is done periodically in line with Calendar of revisions    

Extra-ordinary revisions – not scheduled in the Calendar of revisions. Extra-ordinary revisions include revisions of definitive data due to changes of methodology, changes of classifications, change of base year, changes of mathematical/statistical methods of data calculation. Those revisions may result in a break in time series of data. The users are informed via Press releases in advance.

At present, numeric information on the size of revisions of data is not available.

The policy on vintage database is laid down in the Revision Policy of SOSR. Practical implementation of the policy is being prepared in the statistical information system.       

Vintage database of raw data exists in source database and is not publicly accessible. Data and documents regarding the revision is kept. General information about revision and methodological explanation is published, if relevant.

Coherence of the revision policy is respected for the data released nationally and disseminated to Eurostat.


17.2  Data revision - practice

The primary source of routine revisions is the need of data revisions due to data available from quarterly enterprise surveys, new data received from reporting units or corrected data from reporting units. The revised data for the last 3 months of the quarter are published together with the preliminary results of the following month. The publication of the revised data is done periodically in line with Calendar of revisions.

18  Statistical processingUp
18.1  Source data

Monthly survey Priem 1-12:

All enterprises with 20 and more employees registered in the business register. In addition enterprises in the business register with less than 20 employees that:

— Are statistically important (the decision about including them into survey of big enterprises was done by experts of particular activities, for example responsible for industry data);

— Or have a turnover in excess of EUR 5 million.

Number of units: 2762.

In addition enterprises with less than 20 employees are selected, which are statistically important according to expert judgement.

Trade register

Estimates for sole proprietors performing their business activity on the base of issued trade licences according to Act no. 455/1991 [Digest] (the data source is the number of issued trade licences).


18.2  Frequency of data collection

Monthly data collection.


18.3  Data collection

Data collection is organized by specialised regional office of the SO SR in Banska Bystrica.

The electronic data collection of monthly/quarterly data is compulsory since the 1st January 2016 in line with the obligation laid down in the Slovak National Council law No 326/2014 (Digest) amending the Slovak National Council law No 540/2001 on the state statistics. 

Formal and logical checks are realised in the process of data entry automatically; (compatible with Validation level 0 and 1), informal checks aim of which is to control the complexity and relations among the variables ((compatible with Validation level from 2 to 5). Most of the errors are directly consulted with the reporting units by our regional offices.

Data should be submitted on the 17th calendar day following the end of the reference month. The non-responding units are informed about their reporting duty and contacted by regional offices again. There are no problems with reporting discipline in the case of big enterprises, nevertheless the situation in this area shows the decreased tendency in the last years.

The basic step in the process of unit non-response calculation is the analysis of population with regard to the status of activity of reporting units. For this purpose we use the classification of special response and non-response cases. The particular codes describing active and non-active units are allocated to every reporting unit. Afterwards we define eligible units: they are all active responding and non-responding units. In some cases it is not possible to obtain any information about the unit. In this case we suppose there is the same share of active and non-active units as in the known population. The part corresponding to active units we consider to be non-responding units.


18.4  Data validation

The data entry, data completeness and statistical control are organised by specialised regional offices of the SO SR. 

It has been distinguished between two levels of checking:

1/ Formal checks, which are realised in the process of data entry automatically; (compatible with Validation level 0 and 1).

2/ Informal checks aim of which is to control the complexity and relations among the variables (compatible with Validation level from 2 to 5).

According to the importance there are classified 2 basic types of informal checks:

 I –  Informative check- this check gives the additional information, which is important for the following process of corrections. It informs also about some inconsistencies in the state of fulfilment of the questionnaire, about item non-response, exceeding stated limits etc. 

Z – Check of great importance - it is mostly check indicating the exact error and it must  be always corrected or explained.

Most of the errors are directly consulted with the reporting units by our regional offices.


18.5  Data compilation

Imputation is made from data of the previous months - max. 3 months after surveyed period or is necessary to find a donor.

The results for the population of small enterprises are estimated based on data obtained from quarterly enterprise surveys.

The number of issued trade licenses is used to estimate the sales of sole traders.

18.6  Adjustment

Working day adjustment and seasonal adjustment procedures are carried out using JDEMETRA+ and TRAMO-SEATS.

For details on seasonal and working day adjusment please see the annex.
