|||
3.4. Statistical concepts and definitions | |||
Statistical variables provided by the SPPI surveys are services producer prices and turnover. The services producer prices are in general transaction prices, i.e. the prices of the performed services which enterprise achieves on the market (excluding VAT). All price-determining characteristics of the products are taken into account, including quantity of units sold, transport provided, rabates, discounts, services conditions, subsidies, guarantee conditions and destination. Prices are collected for well specified services for reference quarter and for the previous quarter. Information is also collected on turnover (excluding VAT) for the previous year. STS definition of turnover is used. Turnover comprises the totals invoiced by the observation unit during the whole reference year and this corresponds to market sales of services supplied to third parties. Turnover is used to calculate weights. Turnover covers flows during the calendar year. Information about turnover cover total turnover from all activities of the enterprise and turnover from the specified activities. Share of that turnover by groups of services is also required. |

Observation units
|
|||
3.6. Statistical population | |||
The target population are business entities (legal units, tradesmen and free lances) which perform service activities that are proposed in the Requiremen (listed under 3.3.). The frame for identifying units for the population is the Statistical Business Register. In the case of NACE J61 national regulator obtains the statistical population. Sample frame consists of about 103.900 units. Sample covers about 1.300 units. |
|||
3.7. Reference area | |||
Geographical area covered: Republic of Croatia. |
|||
3.8. Coverage - Time | |||
Time series for SPPIs have different length, depending on when the production of industry index started and how long in the past the backcasting was performed. Some series have data from 2006 but most of them have data from 2010 and some from 2015.
|
|||
3.9. Base period | |||
Base year (the year on which the weights are based) is previous year (2021). Base period (the period to which the index values are compared) is the last quarter of the previous year. Reference year (the year when the index equals 100) is 2015. |
|
|||
The variables for which data are collected are prices (without VAT), expressed in kuna and turnover (without VAT) expressed in thousand kuna. Only price index numbers are calculated as the results of the surveys. Data in absolute figures are not published nationally. |
|
|||
Data on prices are collected in reference period of the quarter with the exception of:

|||
7.2. Confidentiality - data treatment | |||
Confidential data are treated according to policy rules (see point 7.1). Data series on the levels proposed as obligatory by Annex D of STS Regulation for selected activities (listed under 6.2.) are transmitted to Eurostat. For certain service activities in which an observation is based on a very few dominating enterprises data are considered confidential and are marked with the confidential flag. With the first quarter of 2016 price indices started to be regularly nationally published. The same treatment with confidential data has been applied when published nationally as well as when transmitted data to Eurostat. |

|||
10.7. Quality management - documentation | |||
Documentation on quality management is available only for internal users in database specially designed for the purpose of storing information on quality and assessing data quality. |
|
|||
11.1. Quality assurance | |||
There is a written statement under the Official Statistical Act (NN No 25/20) that official statistics in Croatia should be of enough quality. CBS has started systematic approach to quality management with the adoption of the European Code of Practice and with the decision to implement TQM. This process is still in course. Data base for storing information for the purpose of assessing data quality has been developing. |
|||
11.2. Quality management - assessment | |||
CBS has started systematic approach to quality management with the adoption of the European Code of Practice and with the decision to implement TQM. This process is still in course. Data base for storing information for the purpose of assessing data quality has been developing. Overall quality of SPPI indicators is good. Quality is achieved:
|
|
|||
12.1. Relevance - User Needs | |||
User needs are considered almost fully met. Users of the SPPI are: 1. Internal CBS user:
2. External users:
|
|||
12.2. Relevance - User Satisfaction | |||
There is a good cooperation with national accounts as a main users of SPPIs. Also, all questions from users are answered but there is no sistematic way to monitor user satisfaction. |
|||
12.3. Completeness | |||
According to STS Regulation there is one service activity that is not covered by SPPI (M712 Technical testing and analysis) but CBS will be develop in 2023 and disseminate in 2024. Some service activities are still in experimental phase and are not ready to be published. Other services activities are regularly published and sent to Eurostat.
Accorging to new EBS Regulation there is more services activity that has to be included. Service activities that are still not completely developed under SPPI are: H49, H52, I55, I56, J60, L68, M74, N77, N81. Most of these activites were developed in 2022 and disseminated in 2023 and M74,N81 will be develop in 2023. These activities will be developed during the next year. For some activities SPPI survey will be developed and for some activities appproximation will be made. |
|
|||
13.1. Accuracy - overall | |||
CBS does not measure difference between indices calculated with the real population value. It is generaly considered that SPPIs are unbiased and accurate. The main source of errors are:
Indices are not subject to revisions. |
|||
13.2. Sampling error | |||
Most of SPPI surveys are based on a cut-off method where 60% to 70% of total turnover of that service activity is covered. In just a few SPPI surveys PPS sample is used. Those are service activities where there is a lot of small units. Sample error is not measured due to lack of resources. |
|||
13.3. Non-sampling error | |||
The main source of errors is the degree of the accuracy of sample frame and non-response. Non-response amounts 10% on average. Fixed quantity indices may contain a bias as a result from the entry of new services or if significant changes occure in the service structures and weights by industries. The bias caused by new service is minimised by adding new service to the ones monitored with the index. The SPPIs' objective is to measure pure price movements, so changes in the quality must be taken into consideration during the index calculation. This is the main challenge in index calculation, so quality changes are very carefully monitored and treated. Two methods are frequently used: overlaping method and carrying forward method in order to find the price difference equal to the quality difference of the service. If the data are not obtained in two periods, new service is selected. Data collected on prices sometimes are considered as confidential by the reporting units which influences on non-response rate. During the survey conduction great number of units are found not in the scope of the survey. In order to update the sample frame and in order to give a feedback to the Statistical Business Register, based on the information from the survey, units from the sample are classified as:
Double checks and error listings of input data are used to avoid processing errors. |
|
|||
14.1. Timeliness | |||
Results are published no later than 90 days after the reference quarter. Indices are regularly calculated and sent to Eurostat on quarterly basis. Reference period-Date of publishing 1st quarter 2022-30/6/2022 2nd quarter 2022-30/9/2022 3rd quarter 2022-30/12/2022 4th quarter 2022-30/3/2023 |
|||
14.2. Punctuality | |||
There is no time lag between the actual delivery of the data to Eurostat and the target date when it should have been delivered. |
|
|||
15.1. Comparability - geographical | |||
Same statistical concepts are applied in the entire national territory: there is no problem of geographical comparability. Data are also comparable with other member states because the methodology is based on the same regulations. |
|||
15.2. Comparability - over time | |||
Data series for 7 SPPIs developed so far have been compiled from 2006 and are comparable over time (NACE H51, H521, H501_H502, H5224, H531, J61 and N80). Other are available from 2010 and some from 2015. All data series are comparable. |
|||
15.3. Coherence - cross domain | |||
Price movements for several activities in which private consumers are significant are cross-checked with CPI indices like in Regular Air Passenger Transport (NACE H51) and Sea and Coastal Passenger Water Transport (NACE H501). |
|||
15.4. Coherence - internal | |||
SPPI indices are internally coherent. For all NACE areas the same definitions of turnover and output prices are used. |
|
|||
Cost is presented in working hours of CBS staff that is spent on the compilation of producer price index and it is approximately 2500 hours per year. It includes work of 8 persons on 23 rugular surveys and 5 pilot surveys. Burden for reporting units is available for 25 SPPI surveys which are conducted via Internet survey. Reporting units give information on time they spent to fill out the questionnaire only in first quarter of the year. |
|
|||
17.1. Data revision - policy | |||
There is no official revision policy on the level of CBS. The "de facto revision policy" used for this survey includes: - for mayor revisions (such as change of base year) -all series are recalculated but changes are not announced in advance. Explanations are given when new data are published. - if errors occur, corrected data are published as soon as possible or in the next issue of the published. The same revision policy is applied nationally and in transmission to Eurostat. |
|||
17.2. Data revision - practice | |||
The data as indices in original, non-adjusted form are in general calculated and transmitted to Eurostat as final. The exception could occur for data for the first quarter of the year when new sample is drawn and the results are provided before all units from the new sample respond. If error on data occurs, corrected data are transmitted with the next delivery of data. The same revision is applied internally and transmitted to Eurostat. |
|
|||
18.1. Source data | |||
The source for SPPI is in most cases statistical survey. Most of these surveys are web based surveys. In case of J61 Telecommunication sercices, the source is regulatory body. For statistical surveys the frame is derived from Statistical Business Register. The surveys on SPPIs are conducted either by using census (for NACE H51 and J61), cut-off method (for NACE H501_H502, H521, H5224, H53, J58, J59, J62_J63, N732, N78, N79, N80, N812, N82) or sample method (for NACE H494, M691_M692, M702, M711, M731). The sample is updated every year. |
|||
18.2. Frequency of data collection | |||
Data are in general collected on quarterly basis. For NACE H51 data are collected monthly. |
|||
18.3. Data collection | |||
Quarterly questionnaires are used, mostly web questionnaires, in some cases paper questionnaires, and in few cases excel tables sent via e-mail. In future it is planned to convert those paper questionnaires in web questionnaires. Actions taken to speed up or increase the rate of response: automatic reminders sent through the web application, re-contact by mail or by e-mail (written reminders), telephone contacts. |
|||
18.4. Data validation | |||
There is an automatic control during the entering data into the SPPI web aplication. At data entry essential errors are identified which force responding unit or administrator to eliminate them, if not the data could not be successfully send to database. The main checkings are looking for and dealing with the large fluctuations in prices between curent and previous period and with the influence of quality changes on the price movement. |
|||
18.5. Data compilation | |||
The Statistical Business Register is in general used as a frame for sample selection. Unit non-response and item non-response are treated by data editing (imputed). In the index calculation first step is calculation of elementary indices as a ratio of the geometric mean of the prices collected in the observed quarter and the last quarter of the previous year. Elementary indices are aggregated by weighted arithmetic mean. Values of turnover are used for weights. The main source for weights is the SPPI survey itself. Weights (turnovers) are collected for each service group for each enterprise for previous year. Missing prices are estimated as an average change of the rest of prices of the service group (branch). |
|||
18.6. Adjustment | |||
Indices are calculated in original, non-adjusted form. |
