3. Statistical presentation Top
3.1. Data description

Industrial turnover index, derived from the Monthly Survey on Industrial Turnover (IND-2/KPS/M).

Industrial turnover index can be used to show the monthly market evolution of the products and services produced within industry.

3.2. Classification system

Classification: Classification of activity for enterprises and local units by the NKD 2007 (identical on all levels with the NACE Rev. 2).

3.3. Coverage - sector

Activities covered: Enterprises and parts thereof employing 20 or more persons employed and performing one or several industrial activities by definitions of activity coverage of the NKD 2007. (NN, Nos 58/07 and 72/07) for each indicator separately due to the differences in coverage according to legislation of EU.

Size classes covered: Industrial turnover index covers only two industrial sections of the NKD 2007., that is, sections B Mining and quarrying and C Manufacturing, and their divisions 05 – 33. The IND-2/KPS/M Survey for 2022 covers 3 384 enterprises (legal entities and tradesmen).

3.4. Statistical concepts and definitions

The Croatian Industrial Turnover Index is annually chain-linked Laspeyres type index by adoption of currently 2015 as base year. Indices are calculated by aggregation of industrial turnover value data/sales in reporting month.

Industrial turnover indices on domestic market serve to measure monthly movements in industrial turnover/production sold realised by industrial enterprises/industrial local units on the territory of the Republic of Croatia, while on the other hand, industrial turnover indices on non-domestic market serve to measure monthly movements in turnover/production sold realised by industrial enterprises/industrial local units on the non-domestic market, that is, outside the territory of the Republic of Croatia.

List and definition of variables collected: For each enterprise or local unit the following information is collected for each reference month:

  • total income from sales (turnover);
  • income from sales (turnover) on domestic market;
  • income from sales (turnover) on non-domestic market (export);
  • income from sales (turnover) split between euro area and non-euro area.

Accounting conventions: Industrial turnover during the reference (calendar) month.

The value of total industrial turnover that is, income from sales is the invoiced value of reporting local units for the products and services sold during the reference month. It corresponds to the market value of goods and services sold and delivered to third parties on domestic and non-domestic market in the reporting month.

The value of income from sales (turnover) in industry includes all transport and packing costs as well as taxes on invoiced goods and services of the reporting units except the value added tax (VAT). Excluded are all reductions in prices, rebates and discounts as well as the value of returned packed goods, except cash price reductions. Price reductions, rebates and bonuses granted to customers later (e.g., at the end of the year) are also excluded.

3.5. Statistical unit

Reporting units: Enterprises and local units

Observation units: Industrial KAUs performing industrial production within the scope and coverage of the NACE activities for turnover index.

3.6. Statistical population

The statistical population comprises all observation units: enterprises operating in the NACE Rev.2 classes within industrial sections B Mining and quarrying and C Manufacturing, and their divisions 05 – 33 or part of enterprises which secondary activities falls within above described population.

The target population consists of 3 384 statistical units with 20 or more persons employed (cut-off sample) in 2022 for sections covered by this survey. Target population in certain industrial divisions/groups includes the industrial enterprises and KAUs with less then 20 employees if they have a specific industrial production important for the final survey results. 

3.7. Reference area

 The geographic territory of the Republic of Croatia.

3.8. Coverage - Time

The present survey dates from 2005. Data for the industrial turnover index are available from January 2000 onwards on base year 2015 as gross, seasonally and working-day adjusted, working-day adjusted data and trend-cycle.

3.9. Base period

From January 2018 the base year is 2015. (2015=100). Previous base year: (2010 =100).

Reference period is average of previous year. Weights are updated annually in combination with chain linking.

Reference year is also previous year (currently 2021 for 2022 indices)

10.6. Documentation on methodology

Notes on methodology used to compile the industrial production are available at the end of each First Release published on the website: FR IND-2022-4-1 Industrial Turnover Index, 2022

Methodological explanations are also available in other monthly or yearly publications which includes the Industrial Turnover Index and in Statistical Database (section Industry).

10.7. Quality management - documentation

Documentation on procedures applied for quality management and quality assessment are under development within TQM framework. Quality database is developed and quality reports for ITI are available on CBS website for all users, free of charge.


11. Quality management Top
11.1. Quality assurance

To assure the quality of processes and products, CBS applies the European Statistics Code of Practise and the ESS Quality Assurance Framework (QAF). CBS is also guided by the requirements provided for in the Official Statistics Act (OG, Nos 25/20).

The Quality Database is based on the exhaustive list of quality information, which has been based on two widely accepted ESS structures, ESMS and ESQRS.

11.2. Quality management - assessment

The Industrial Turnover Index is highly relevant both as an input to quarterly national accounts and stand-alone. The type of survey and the data collection methods ensure sufficient coverage and timeliness. The level of the accuracy is high. It is usually published on the 27th day in a month for the indices from previous reference month. Publication of results are always punctual, fast and easy accessible. Notes on methodology are clear and comprehensive for demanding users’ needs.

Industrial Turnover Index is internationally comparable since follows EU and relevant international concept, definitions and classifications. The main advantage is comparability over time with the length of time series since January 2000. It is comparable with other statistical domains, primarily with the quarterly national accounts and PRODCOM. 


12. Relevance Top
12.1. Relevance - User Needs

Primary users of ITI:

  • International users: Eurostat, ECB, IMF, UN/ECE, OECD
  • National users: Croatian National Bank, Ministry of Economy, Ministry of Finance, other government bodies, Institute of Economic Zagreb (EIZ), Croatian Chamber of Economy
  • Internal users: National Accounts Department

Secondary users of ITI:

  • trade unions, enterprises/business
  • economic and research institutes, researchers and students,
  • media and general public. 
12.2. Relevance - User Satisfaction

In April 2015 Croatian Bureau of Statistics (CBS) conducted the user satisfaction survey for the second time (first time in November 2013). The aim of the research was to determine users' satisfaction with the quality of data and services, as well as their needs. The survey was conducted on a sample of the CBS data users combining web questionnaire and telephone interviewing in the period from 13 to 26 April 2015. 

The sample consisted of users that have requested statistical data in the period from the beginning of the 2013 to March 2015. The questionnaire was sent to e-mails of 2 765 users through the Survey Monkey. Links to the questionnaire were placed on the website of the CBS, as well as on CBS official Twitter and Facebook pages so that other interested users can participate in the survey. Questionnaire was completed by 952 users.

CBS's data users were mostly woman (61.7%). The majority of users (56.6%) belonged to the age group 30-49 years. 52.8% of users had university degree, 22.7% of users were researchers and the second largest group of users was from the field of economy (21.5%). 

Out of the total number of surveyed users, 88.6% collected data through CBS's website, 55.9% of users collected data for research purposes, 36.4% for general information only, 24.7% of users used data each month and the most demanded data were from the field of population (46.4%), employment (40.2%) and tourism (30.8%). 65.7% of users thought that CBS's data is of high quality and 62% of users rated the comparability of CBS' data as good. Part of users (21.2%) believed that CBS' data did not meet their needs for statistics in the Republic of Croatia and 18.8% of users were not satisfied with the way they can acquire CBS data.

 

The following five criteria were taken as the variables that affect the overall satisfaction of CBS' users:

  • satisfaction with the employees - average grade is 4.34
  • satisfaction with data - the average grade is 3.56
  • satisfaction with the website - the average grade is 3.16
  • satisfaction with the CBS in general- the average grade is 3.8
  • trust – CBS has reliable data - the average grade is 3.96.

Total CBS average grade is 3.8 and the overall index of the users' satisfaction with the CBS is 75.28%.

12.3. Completeness

Time series for Industrial Turnover Indices, total industry, MIGs, domestic and non-domestic market are available since 2000 based on NACE Rev.2 (base year 2015=100).

Eurostat's requirements in terms of time series are fulfilled.


13. Accuracy Top
13.1. Accuracy - overall

The Monthly Survey on Industrial Turnover (IND-2/KPS/M) is based on a cut-off sample. Sampling error is not measured. The response rate is very high so the overall accuracy is very good.

13.2. Sampling error

Not available. Industrial Turnover Index is calculating based on a cut-off survey (industrial enterprises with 20 or more persons employed).

13.3. Non-sampling error

Response rate is 100% for those 63 respondents filling the e-form. In the case of item non-response the missing response are requested by telephone contacts. This case is very rare (only possible for limited number of forms send by email) since usage of on-line data collection system ensuring that all fields should be fulfilled prior to sending. Thus item non-response for Industrial Turnover Index =0%.

For units which data are taken from administrative source (VAT) the response rate is very high- about 98%. Up to 2% enterprises do not fill the monthly VAT so the missing values are automatically imputed according to the procedures for non-response.

In the case of unit non-response, two types of estimation methods are being used:

  • based on previous month record/or based on production trends of this unit starting from the beginning of current year up to the end of the previous month
  • based on production trends of the same product groups of other statistical units within 8-digit level (if there is no report from the previous months by statistical unit)

Measurement errors: The data collection through the electronic form on the CBS website has highly reduce the possibility of calculation errors, incorrect codes and measurement units. Also there are incorporated various warnings when submitting a form if there is a visible oscillation between previous months. Errors by companies entering the incorrect data are also possible and these data don't pass editing process. All the errors are treated, analysed and consulted with the enterprise and corrected via direct telephone contact or by e-mail.

Very detail micro table exist to be checked each respondent on class level (value of production sold) to find possible discrepancies. Data are corrected via control programme support (SQL) always on micro basis after obtaining corrected data from enterprise (whatever via direct telephone contact or by email)

Aggregate checks: data are checked on different level of aggregations firstly by persons responsible for particular activity divisions, then by supervisors and head responsible for total Industrial Turnover Index. Special table for macro level analysis exist in Excel sheets for final data/indices checking as result from computer programme support. If there will be need for data correction due to unrealistic values confirmed by enterprise then data will be correct on micro level, and all treatments should be repeated.


14. Timeliness and punctuality Top
14.1. Timeliness

A combined method of using two data sources was used to gather data: administrative source (98.1% of units) and statistical source in the way that data were gathered directly from reporting units (1.9% of units), mostly from large enterprises where the reporting method via a web-based application (the so-called CAWI) is applied.

Timing of production observations: Frequency of data collection is monthly. The time schedule for data collection ranges each month, as a rule between 1st and 14th day in a month for the previous reference month data. Data on reporting units that are taken over from the administrative source (VAT) are collected 45 days after a reference month, at which point they are available to the Tax Administration and further processed in the Croatian Bureau of Statistics for statistical purposes.

Timing of publishing: Industrial Turnover Index data are being published 57 days after reference month (t+57) for total industry, according to MIGs 2009 and according to market, domestic and non-domestic market, in unadjusted, working day adjusted, seasonally adjusted and trend cycle time series.

The first results are also the final results.

14.2. Punctuality

All the Industrial Turnover Index First Releases for 2021 have been published at 11 o'clock on the day announced in the Calendar of Statistical Data Issues, 2022.


15. Coherence and comparability Top
15.1. Comparability - geographical

Since Croatian Industrial Turnover Index is in compliance with STS requirements it is comparable among Member States.

15.2. Comparability - over time

Time series for Industrial Turnover Indices, total, domestic and non-domestic market are available since 2000 based on NACE Rev.2 on 2-digits devision and sections level as well as on MIGs.

Monthly time series for Industrial Turnover Indices are available since January 2000 for total industry, MIGs, domestic and non-domestic market based on NACE Rev.2  (base year 2015).

The transition from NACE Rev.1.1 to NACE Rev.2 was performed by backcasting in combination of micro/macro level to ensure comparability over time.

15.3. Coherence - cross domain

Consistency with annual indicators is achieved by confrontation of annual turnover data with:

  • Annual PRODCOM survey data on industrial production sold, where data are being collecting from enterprices and local units with 10 and more persons employed within NACE Rev.2 sections B and C.
  • Annual SBS results in regard turnover data, where data are derived from FINA (administrative data) and represent hole enterprises population within NACE Rev.2 sections B and C.
15.4. Coherence - internal

The Industrial Turnover Index is annually chain-linked Laspeyres type index. The higher level indices are annually chain-linked using an annual overlap (annual average of year t-1). The chain linking is performed to hieratical level of NACE as well as on aggregate sub-indices levels (MIGs), domestic and non-domestic market and total industry. The Industrial Turnover Index is internally consistent within available time-series since January 2000 to December 2022. It is compiled as unadjusted, WDA, SA and trend-cycle indices. Up until now, the TRAMO-SEATS method was used in the Demetra (version 2.2.) package. Since January 2016, the new X13 ARIMA method in the new JDemetra+ package has been used, on a time series starting from January 2000.

Industrial Turnover index adjustments are made for the Industry total, MIGs, domestic and non-domestic market using direct method i.e. Industrial Turnover index time series are aggregated by NACE , MIGs and domestic/non-domestic market then seasonal adjustments performed independently at each aggregate level.

Coherence is achieved by compilation methods and weighting system. Industrial Turnover index for various levels of the NACE are calculated for indices on group levels and higher by weighting with the share in value of turnover (sales) for defined industrial activities according to NACE in respect with each indicator. Indices for MIGs aggregatesare calculated in the same way as well as indices for domestic and non-domestic market.


16. Cost and Burden Top

Starting from January 2010 data collection method for Monthly survey on industrial turnover has been change. WEB based "on-line" questionnaires has being introduced instead of paper questionnaires (CAWI method) to reduce both burden on statistics and no respondents. Data collection chain has been change from decentralised (via county statistical office) to completely centralised (CBS headquarter). As a consequence, cost and burden originated from statistical data collection was significantly reduced for both, respondents and statistics.

Cost for statistics is approximated as follows: The routine costs in Croatia for updating Turnover weights each year are approximately 2 persons for 2 month (January to February) intensively in normal year where no revisions occur due to classifications change. It currently involves four experts manual work in the excel sheets tables approximately 360 hours per expert. In addition, updating the software for data collection, processing and calculations (especially new database construction in SQL) approximately 1 IT persons is needed to work app. 7 days along with experts.

The data collection method for IND-2/KPS/M Survey used in 2022 has remained the same as previous year to reduce the reporting burden for small and medium size enterprises and to increase the quality of the results. Therefore, in 2022, a combined method of using two data sources was used to gather data: administrative source (98.1% of units) and statistical source in the way that data were gathered directly from reporting units (1.9% of units), mostly from large enterprises. For these 63 respondets the response burden is very low. They need in average 10 to 15 minutes for fulfilling “on-line” questionnaire.


17. Data revision Top
17.1. Data revision - policy

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

The General Revision Policy of the Croatian Bureau of Statistics is based on the following documents:

17.2. Data revision - practice

The revision policy in practice depends of size of revision.  In the case when major changes in methodology occurs first there are discussions with the Statistics Advisory Committee for Industry (users and producers) about the proposed new Statistical Standards. These are issued after agreement with description of major changes or revisions under chapter Comparability with previous data series. The Annual Implementation Plan (Annual statistical programme), 2022 also includes such information’s.

Users are informed on minor methodological changes in Note on methodology which is a part of the First release and all related publications announced in the Calendar of Statistical Data Issues, 2022 which is all available on CBS website.

Croatia has no practice to publish preliminary and final Industrial Turnover Index results. It is always published as final results 57 days after reference period (mark as „first results„ since detailed results could be found in comprehensive dedicated statistical report). If revision will be needed due to integration of new significant information for Industrial Turnover Index unadjusted results on 3 digits NACE level (more than +/- 0.5), apart from revisions generated by seasonal adjustment, then in practice revised data will be mark and explain to users.

Industrial Turnover Index revisions generated by seasonal adjustment on the past data are not explaining to the users apart from explanations within Note on Methodology (part of each Industrial Turnover Index First release) about nature of implemented seasonally adjusted methods (size of revisions due to the seasonal adjustments was not measured so far).

Revisions due to errors are mark and explained to users almost immediately after detection in the reissued First release (available on CBS website).


18. Statistical processing Top
18.1. Source data

A stand-alone monthly survey known as the Monthly Survey on Industrial Turnover (IND-2/KPS/M form) is the main source of information for calculating Industrial Turnover Index.

The IND-2/KPS/M Survey covers enterprises and parts thereof employing 20 or more persons employed and performing one or several industrial activities in two industrial sections of the NKD 2007 (NN, Nos 58/07 and 72/07), that is, sections B Mining and quarrying and C Manufacturing, and their divisions 05 – 33.

The target population for 2022 included 3 384 industrial enterprises and KAUs.

18.2. Frequency of data collection

Frequency of data collection is monthly, with deadline around 27th in the current month during 2022. Actual reporting dates are between 1st and 15th of the month (for previous reference month data). Data on reporting units that are taken over from the administrative source (VAT) are collected 45 days after a reference month.

18.3. Data collection

A combined method of using two data sources is used to gather data: administrative source (98.1% of units) and statistical source in the way that data were gathered directly from reporting units (1.9% of units), mostly from large enterprises where the reporting method via a web-based application (the so-called CAWI) is applied, i.e. reporting units fill in data directly onto the IND-2/KPS/M e-form, which is available on the CBS web site.

Notification e-mail with the deadline for fullfiling the survey are sent to respondents which need to fill in the e-form. Later, e-mail reminders are sent to increase and speed up the rate of response. 

Missing responses are requested by telephone contacts. Imputation is used to compensate the non-response.

18.4. Data validation

The CBS industrial experts perform all cross-checking, necessary correction after phone call-back procedure for suspicious data, and if it is necessary visiting respondent will be advanced - that is the long-term practice of industrial statistics department to obtain data of good quality. Processing is being verified automatically through established procedures of data treatment and validation each month within production quantities and cumulatively quantities (from the beginning of the year) are confronting and crosschecking. Validation includes: cross cutting checks, checks with previous data, evolution checks (very strict criteria).

All processing steps from validation to computing the chain-linking Industrial Turnover Index including national dissemination formats is carrying out in automatic IT support system (SQL) and before the data are to be prepared for transmitting to Eurostat. The structure of the file and the format of the data to be sent to Eurostat are derived from national formats of final results as well as plausibility checks and consistency checks which are incorporated in national data validation system. The file format for Eurostat is formatted as Excel file as required by GESMES/TS Guide and Industrial Turnover Index required results are manually input from national formats. Eurostat specific validation checks are not carrying out so far since national validation rules are more strictly.

18.5. Data compilation

Industrial Turnover Index in Croatia is Laspeyres type chain index using annual overlap. The chaining and base period is averege of previous year. Weights used are sheres of value of turnover (sales).

The chain linking is performed at each level of aggregation starting from hierarchical level of NKD 2007 (=NACE Rev.2) classes, groups and divisions as well as on aggregate sub-indices levels (domestic and non-domestic market) and total.

Indices of industrial turnover for the different levels of NKD 2007 are calculated for indices on group levels and higher by weighting with the share in value of turnover (sales) for defined industrial activities according to NKD 2007. Indices for MIGs 2009 aggregatesare calculated in the same way as well as indices for domestic and non-domestic market.

The structure of industrial activities (division structure) has been calculated for the industrial turnover index on the basis of the turnover value (sales) by using the pure activity principle for the Republic of Croatia in 2020. It was calculated on the basis of the 2020 annual statistical results of the Structural Business Survey carried out by the Croatian Bureau of Statistics and by processing annual administrative data taken over from Fina – the Annual Accounts of Industrial Enterprises in 2020, after which it was corrected by using the results of the PRODCOM Survey on Industrial Production for 2020. For the calculation of domestic and non-domestic market indices, the structure calculated on the basis of the PRODCOM Survey on Industrial Production for 2020 is used. The division structure is updated at the beginning of every year for the calculation of indices of a current year.

18.6. Adjustment

Industrial Turnover Index is compiled as unadjusted, WDA, SA and trend-cycle indices. Seasonal and working-day adjustment has been done by using the X13 ARIMA method in the JDemetra+ package, on a time series from January 2000. Direct method is used for the seasonal adjustment of time series.

In the seasonal adjustment the impact of the number of working days, Easter and other national holidays (National Calendar is in use) was taken into account in those time series for which the mentioned influences were statistically significant. These adjustments are made for the total industry (sections B ansd C of NACE Rev. 2,  MIGs 2009., domestic and non-domestic market.
