71 – Renting of machinery and equipment without operator and of personal and household goods,
72 – Computer and related activities,
73 – Research and development,
74 – Other business activities,
75 – Public administration and defence; compulsory social security,
80 – Education,
85 – Health and social work,
90 – Sewage and refuse disposal, sanitation and similar activities,
91 – Activities of membership organizations,
92 – Recreational, cultural and sporting activities,
93 – Other service activities.
- They are provided in order to make profits. As for institutional sectors, market services comprise entities from the sector 11 (non-financial enterprises) and sector 14 (households – unincorporated natural persons). To put it simple, budgetary and allowance organizations are classified to non-market services. CZ-NACE Divisions 75 and 91 are mentioned only to make the listing of activities complete, number of units classified to the sector 11 or 14 is very small and thus data for these two CZ-NACE Divisions are not published separately.
The publication comprises of two parts.
Part A: Results of quarterly surveys
Data in the first part of the publication result from the processing of the quarterly questionnaire P 3-04. For the selection of businesses included in the survey we used administrative sources that are included in the Business Register. Medium-size businesses (usually with 20 – 99 employees) fill the questionnaire P 3(b)-04 and large businesses (usually with 100 and more employees) the questionnaire P 3(c)-04. Individual “mutations“ of the questionnaire P 3-04 differ as for the number of indicators required; basic indicators have the same methodological determination and are measured by both the questionnaires. In total, the quarterly questionnaire in the services branch was sent to approximately 3.5 thousand units; response rate (percentage of filled-in questionnaires that came back) was 82,4 %. Data for the set of units that do not receive the quarterly questionnaire (small businesses, usually with less than 20 employees or without employees) are estimated using information from monthly surveys SP 1–12 and then specified according to the last results of annual surveys available (now we have preliminary processed annual questionnaires for the year 2001).
For statistical surveys in 2003 the CZSO started to use information on economic activity of enterprises from available administrative sources. This methodological change was reflected in the creation of populations and samples as well as in the processing of the results of surveys. The results of the survey for 2002 were calculated retrospectively by the same method. For the above-mentioned reasons, data for the previous year differ from the data published in 2002; data in this publication for both years are comparable as for methodology.
The publication contains basic indicators by individual Divisions (2-digit codes) of CZ-NACE, an overview of financial indicators for large businesses (with 100 and more employees) in total, from that for foreign controlled enterprises (sub-sector 11003). The graphical part contains graph of development of average wages, structure of sales and employment by size of enterprises and individual Divisions of CZ-NACE.
Financial indicators (where not mentioned otherwise) are in current prices.
Part B: Monthly surveys
Data in the second part of the publication are the results obtained from the processing of the monthly questionnaire SP 1-12 only for the following Divisions of CZ-NACE:
70 – Real estate activities,
72 – Computer and related activities,
74 – Other business activities,
93 – Other service activities.
Until 2002 results of this survey were published monthly in the joint publication Results of Monthly Survey on Services (code of publication in the Catalogue of Publications 2002: 9002-02), in 2003 only data for trade, hotels and restaurants are published with monthly periodicity. Information on the development of services in the Czech Republic are also regularly released in News Releases presented by the CZSO on its web sites always on the 33rd working day after the reference quarter.
The monthly statistical questionnaire SP 1-12 monitors development of the branch measured by the sales index. Reporting units with 100 or more employees are covered all, and smaller enterprises by way of samples, whose size depends on the share of the total number of units in a given size group to those in the 3-digit Group of CZ-NACE. Groups of enterprises with low numbers of employees that, according to the Business Register, are not numerous, are covered all by the survey. In groups where random sampling is applied, so-called rotation takes place, i.e. partial substitution of the sample, aimed at updating the set of reporting units on the one hand, and keeping comparability with data produced previously on the other. As a result, randomly chosen enterprises principally remain in the sample for four consecutive years and then they are substituted. In total, the monthly questionnaire in the market services branch was sent to about 4.7 thousand units, response rate (percentage of filled-in questionnaires) differs in individual months – the number of received questionnaires for the currently processed month is lower, average response rate for the fourth quarter of 2003 is about 62,9 %.
The questionnaire SP 1-12 measures sales, both including VAT and not including VAT; sales excluding VAT are used to calculate the sales index (with the exception of CZ-NACE 93, for which sales including VAT are used). It is supposed for this monthly survey that the number of units is constant throughout the year: therefore, the results of the monthly survey may differ from the results produced by quarterly or annual surveys whose purpose is to estimate not only the index, but the absolute volume of sales, and that is why they take into account also the changing number of enterprises in individual periods. Different samples in some of the Divisions of CZ-NACE with large variance in sales are another cause of possible discrepancies.
In compliance with the re-basing of price indices (2000 average becoming the base) used by the CZSO as from January 2001, the calculation of the sales index was changed accordingly. Aggregate indices now use the weights of 2000. Sales measured by the monthly survey at the level of 3 digits of CZ-NACE in individual months of 2000 serve as the weights. Y-o-y sales indices at current prices are derived from the monthly survey for each deepest CZ-NACE level. There has been no change in this point of the calculation. For the same CZ-NACE levels, the price statistics produces also y-o-y price deflators for individual months and price deflators of individual months related to the 2000 average.
Using the chaining of deflators, monthly sales at current prices for the deepest CZ-NACE levels are converted to the 2000 price level. The sum of sales at constant prices gives aggregate sales (for 2-digit CZ-NACE) at constant prices, which provide a basis for the calculation of y-o-y indices at constant prices. Aggregate deflator is a ratio of aggregate sales at current and constant prices. The sum of 2000 monthly sales at current prices amounts to the sum of sales at constant prices.
The time series of indices re-based to 2000, covering 1997-2000, were made available in the publication “Results of Monthly Survey on Services for June 2001” (code of publication 9002-01, released on 31 August 2001). Data for current year are retroactively updated on a regular basis, using questionnaires received after deadline. Final data for 2003 will be published in half 2004, data for 2002 are already final.
This publication contains y-o-y and basic indices (average of year 2000 = 100) of sales in current and constant prices seasonally non-adjusted, graphical part shows development of sales since 2000, namely in the form of basic indices seasonally non-adjusted, y-o-y indices and trend (after seasonal adjustment).
