3.1. Data description

Enterprises are requested to provide annual information on actual and sold production quantities and production sold value for all products and services described in the PRODCOM based national Nomenclature of Industrial Product (NIP). The NIP has a wider scope then PRODCOM and hierarchically cover all products and services described in the NACE Rev.2 section B to E36 i.e. CPA ver.2 respectively. It is updating annually in line with PRODCOM.

The production sold quantities and values for each NIP code is further split on production sold on non-domestic market. This is mainly used as source to calculate weights needed for the STS Producer Price Indices (PPI) and energy statistics.

Volumes are requested for all products (even for those for which no European obligation exists). For some products, if European chosen unit does not match national needs, volumes in several units might be requested.

For contract activities the number of effective hour is used as volume (this is used for weighting measurement) in addition to fee received for contract work

The data collection is made at the level of the county. Enterprises are split in entities that cover each region (21 Croatian Counties). Several local units might be grouped together if they are in same country.

Due to Covid 19 pandemic outberak, there was no effect on data collection.

3.2. Classification system

Hierarchical Nomenclature of Industrial Products, 2020 (so called NIP 2020) is used in the PRODCOM survey on industrial production for 2020. NIP code follow the identical structure as PRODCOM comprising in first 6 digit CPA codes, 8 digits PRODCOM codes and further national breakdown on 10 digits level. Part that are not covered by PRODCOM comprise further breakdown of CPA codes.

The NIP 2020 covers all products listed within the Prodcom list 2020 with further national breakdowns and extra products for NACE activities based on CPA Ver 2.1 not covered by PRODCOM list 2020 due to national needs (NACE Rev.2 sections B to E36 are covered). NIP 2020 consist of about 4324 (while PRODCOM list 2020 has about 3935 products).

The NIP is revised every year according to PRODCOM list.

3.3. Coverage - sector

Nomenclature of Industrial Product (NIP) covers sections and divisions from B to E36 of Nace Rev.2 (while Prodcom covers only sections B and C of NACE Rev.2)

In the national PRODCOM survey enterprises and part thereof under above defined coverage with 10 and more persons employed are surveyed.

3.4. Statistical concepts and definitions

The PRODCOM based survey in Croatia collects more data than what is required at European level.

Folowing variables are collected on the NIP level: 

The value and the volume of production. The value is expressed in national currency – Croatian 000’ Kuna’s but for the purpose of delivery to Eurostat converted to Euro. The volume is expressed in a unit specified for each NIP product.

The volume unit: the measurement unit, such as kilograms, square metres etc.,to indicate the volume of physical goods produced, while for certain services and subcontracting work effective hours are used to indicate the volume of services under subcontracting produced.

Production type:

  • Total Production (the volume of all production of the product, including both the proportion that is sold and the proportion that is retained by the enterprise for adding to stocks, using in further processing etc.)
  • Sold Production as the total value and volume of the product sold by the enterprise
  • Of which sold production in value and volume sold abroad/exported

Only production carried out within national border is reported.

3.5. Statistical unit

The industrial enterprise and industrial parts of non-industrial enterprises (KAU) is the observation unit surveyed by the CBS. Additionally, enterprises and parts thereof are split in entities that cover each region (21 Croatian Counties). Several local units might be grouped together if they are in same county (kind of broad Local unit) due to national needs (data on county levels).

The production for each Prodcom product from all surveyed enterprises and part thereof in the Croatia is aggregated before the results are sent to Eurostat.

3.6. Statistical population

The survey population of the reference period shall be enterprises whose principal activity or one of its secondary activities with 10 or more persons employed is listed in section B, C, D and E36 of the NACE Rev.2. For bakeries and printing, the number of persons employed is to be reduced to get significant coverage of turnover of the division.

3.7. Reference area

Due to Covid 19 pandemic outbreak, there was no effect on data collection.


12. Relevance Top
12.1. Relevance - User Needs

PRODCOM is highly relevant for national and international users as well as internally (as for input to input-output tables).

  • International main users: Eurostat, ECB, IMF, UN/ECE, OECD, FAO.
  • National main users: Croatian National Bank, Ministry of Economy, Ministry of Finance, other government bodies,  Institute of Economic Zagreb (EIZ).
  • Other users: Trade Unions, businesses, researchers and students, media, general public.
  • Internal users: National Accounts, etc.
12.2. Relevance - User Satisfaction

CBS was conducted first general user satisfaction survey during November 2013 and secondly in period from 13 to 26 April 2015 combining web questionnaire and telephone interviewing.

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.

The questionnaire was prepared in Croatian and English and contained 28 questions. In specific parts of the questionnaire, users were able to write their proposals and suggestions for improvements.

The questionnaire covered the following topics:

  • demographic characteristics of users,
  • usage and quality of statistical data,
  • satisfaction with CBS website,
  • satisfaction with the employees and the quality of services,
  • as well as questions about the CBS on social networks.

Questionnaire was completed by 952 users.There was no specific question on PRODCOM data.

The starting point of creating a model for measuring users' satisfaction was the American Customer Satisfaction Index (ACSI).The following five criteria were taken as the variables that affect the overall satisfaction of CBS' users.

  1. Satisfaction with the employees (question 20) - average grade is 4.34
  2. Satisfaction with data (question 9) - the average grade is 3.56
  3. Satisfaction with the website (question 14) - the average grade is 3.16
  4. Satisfaction with the CBS in general (question 23) - the average grade is 3.8
  5. Trust – CBS has reliable data (the claim in question 11) - the average grade is 3.96.

Detailed results are available on CBS web-site: http://www.dzs.hr/Eng/international/Quality_Report/Quality_Report_Documents/Quality_Report_Satisfaction_Survey.pdf

12.3. Completeness

According to "compliance score" calculated by Eurostat Croatian PRODCOM data for 2020 reached full compliance. A compliance score combines the timeliness of the transmission with the percentage of data reported. Croatian PRODCOM data 2020 includes 100% of the data in the transmission file on time requested.


13. Accuracy Top
13.1. Accuracy - overall

The PRODCOM Survey for 2020 covered 2905 enterprises with a response rate of 97.60% while the non-response estimate was 2.40%, the overall accuracy is very good.

13.2. Sampling error

Not applicable. PRODCOM survey is a cut-off survey (with 10+ persons employed).

13.3. Non-sampling error

Measurement errors: Respondents are not likely to use wrong code as the classification of product is usually done by the statistical office.

Processing errors: When data are collected they are compared with other sources:

  • Accounting declaration (fact that registration number is the same for statistics and accounting helps)
  • Correspondence with monthly declaration for enterprises of 20+ employees that are reporting in the monthly industrial survey.
  • A threshold of +/- 30% is considered as acceptable;Comparison between unit values

Aggregate checks:

  • Data are checked on deferent level of aggregations firstly by persons responsible for particular activity divisions, then by supervisors and head responsible for total PRODCOM results.
  • 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.

Unit non response rate is 1.0%.

Item non-response is 0, actually not applicable since in-line Prodcom data collection system in Croatia does not allow not recording of any item.

Imputation rate is not available, since systematic imputation does not exist. Data have being imputed manually based on the enterprise feadback or expert judgment and currently data processing system make no differences whether data originate from enterpises or they are imputed manually by CBS staff.

Impact of COVID 19

There was no impact of covid 19 on data sending


14. Timeliness and punctuality Top
14.1. Timeliness

Timing of delivery to Eurostat: RODCOM First results are delivering to Eurostat M+6 for previous year results. Final PRODCOM results are delivering M+9 to Eurostat.

Timing of national publication: PRODCOM first results (aggregate results) data are being published 10 months after reference year (M+10). Detailed (final) results on products level are being published 15 months after reference year (M+15).

14.2. Punctuality

Publications of PRODCOM results are always being punctual.

PRODCOM first releases for 2020 have been published according to the pre-announced Calendar of Statistical Data Issues, 2021. 

Detailed PRODCOM results 2020 folowing Statistical report will be published according to the announced Calendar of statistical data issues, 2022, 31st of March 2022.


15. Coherence and comparability Top
15.1. Comparability - geographical

Since Croatian PRODCOM results are comparable among Member States since it follows EU recommended methodology and PRODCOM list regulations.

15.2. Comparability - over time

Annual PRODCOM results on product level are available since 2008 reference year based on NACE Rev.2.

Annual PRODCOM results prior to 2008  (from 1995) are available on appropriate PRODCOM List required for reference year in question.

15.3. Coherence - cross domain

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

  1. Monthly survey on industrial production and persons employed (IND-1/KPS/M), where data are being collecting from enterprises and local units with 20 and more persons employed within NACE Rev.2 sections B and C.
  2. Annual SBS results in regard turnover data, where data are derived from FINA (administrative data) and represent whole enterprises population within NACE Rev.2 sections B and C.
15.4. Coherence - internal

Very detail micro table exist to be checked each respondent on products level (total production, 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 (whether via direct telephone contact or by email).


16. Cost and Burden Top

Starting from 2012 data collection method for Annual PRODCOM survey on industrial production 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.

Burden on respondents are also significantly reduced due to web-based data collection since the web questionnaire is prefilled and there is no cost associated with delivery of questionnaire.


17. Data revision Top
17.1. Data revision - policy

There is no clear revision policy on Croatian statistics level, except that in the case of mistake revised data is mark and explained to users in all publication.

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), 2021 also includes such information’s which are available on CBS website (free of charge).

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 Issues, 2021 which is all available on CBS website (free of charge).


18. Statistical processing Top
18.1. Source data

Annual PRODCOM survey on Industrial Production (IND-21/PRODCOM/G form) is the main source of information for PRODCOM products within NKD 2007. (=NACE Rev.2) sections B, C, D& E36.

The survey covers approximately 90% of total value added (VA) of industry on 4-digits levels of the NKD 2007 (=NACE Rev.2).

A data are obtained from a annual industrial survey for all units with 10 or more persons employed but in particular cases less than 10 are covered when it is not possible to achieve 90 % of value added on NKD 2007 on 4-digits level.

18.2. Frequency of data collection

Annual

18.3. Data collection

Customized web-based questionnaires (CAWI method of data collection) are being used for data collection from 2012.

Reporting units are obliged to fulfil the data concerning their production annually in period from 15th of March to 15th of May in current year for previous year data via CBS web-site.

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 within production quantities and quantities and values of production sold are confronting and crosschecking with previous year data.

Validation includes: cross cutting checks, checks with previous data, evolution checks (very strict criteria).

All processing steps from validation to computing 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.

Eurostat specific validation checks are carrying out as well.

18.5. Data compilation

Data are compiled on aggregate PRODCOM product level as well as of NACE Rev.2 levels.

Additionally, data are compiled on Croatian counties level (only NACE sections).

18.6. Adjustment

Not applicable.
