3.1. Data description
Statistics on Private non-profit R&D (PNPRD) measure research and experimental development (R&D) performed in the private non-profit sector, i.e. R&D expenditure and R&D personnel. In line with this objective the target population for the national R&D survey of the private non-profit sector should consist of all R&D performing units (including all R&D performers – occasional and continuous, known and unknown - in all branches and size classes) belonging to this sector.
The main concepts and definitions used for the production of R&D statistics are given by the OECD (2015), Frascati Manual 2015: Guidelines for Collecting and Reporting Data on Research and Experimental Development, The Measurement of Scientific, Technological and Innovation Activities, which is the internationally recognised standard methodology for collecting R&D statistics and by Eurostat’s European Business Statistics Methodological Manual on R&D Statistics (EBS Methodological Manual on R&D Statistics)..
The guiding document to preparing the quality reports is the European Statistical System (ESS) Handbook for Quality and Metadata Reports — re-edition 2021.
Since the beginning of 2021, the collection of R&D statistics is based on Commission Implementing Regulation (EU) No 2020/1197 of 30 July 2020. The Regulation sets the framework for the collection of R&D statistics and specifies the main variables of interest and their breakdowns at predefined level of detail.
3.2. Classification system
- The distribution of principal economic activity and by product field is based on Statistical classification of economic activities in the European Community (NACE Rev. 2);
- The local units for the statistics are compiled at regional level according to NUTS 2 – Nomenclature of Territorial Units for Statistics;
- The distribution by socioeconomic objectives (SEO) is based on Nomenclature for the Analysis and Comparisons of Scientific Programmes and Budgets (NABS);
- The fields of research and development based on Classification and distribution by Fields of Research and Development (FORD);
- The R&D personnel and researchers by educational attainment are classified by the International Standard Classification of Education ISCED 2011
3.3. Coverage - sector
See below.
3.3.1. General coverage
Definition of R&D
R&D comprise creative and systematic work undertaken in order to increase the stock of knowledge - including knowledge of humankind, culture and society - and to devise new applications of available knowledge.
The R&D definition used in the survey is fully in line with the Frascati Manual definition.
3.3.2. Sector institutional coverage
| Private non-profit sector | Private non-profit sector comprises non-market, non-profit institutions serving households (that is, the general public), except those mainly controlled and financed by government, their main characteristic being that they should not be the source of revenue or profit to the institutions controlling them. |
|---|---|

3.4.2.2. R&D personnel – Full Time Equivalent (FTE)
| Coverage of years | Calendar year 2023 |
|---|---|
| Function | Data on R&D personnel in full-time equivalent by occupation are available and broken down by four types of function (researchers, expert associates, technicians and other supporting staff). The concept of calculating full-time equivalent was sometimes difficult to understand despite the provided instructions in the questionnaire. |
| Qualification | Data on R&D personnel in full-time equivalent by qualification are collected and available according to ISCED-2011 at levels 0-8. No difficulties were encountered. |
| Age | Data on R&D personnel in full-time equivalent by age are not available. |
| Citizenship | Data on R&D personnel in full-time equivalent by citizenship are not available. |
3.4.2.3. FTE calculation
In the questionnaire we ask reporting units to fill in the FTE directly. Also we provide instructions and examples for filling in the data on FTEs as help:
- 3 persons working on R&D half-time (50%) during entire year = 3 x 0.5 = 1.5
- 2 persons working on R&D part-time (20%) during entire year = 2 x 0.2 = 0.4
- 1 person working on R&D full-time (100%) half a year = 1 x 0.5 = 0.5
- 2 persons working on R&D part-time (25%) during 8 months = 2 x (8/12) x 0.25 = 0.3
3.5. Statistical unit
The statistical unit is the institutional unit as defined by Council Regulation (EEC) No 1993/696 of 15 March 1993. There are no deviations.
In PNP, the statistical unit is legal unit.
3.6. Statistical population
See below.
3.6.1. National target population
The target population is the population for which inferences are made. The frame (or frames, as sometimes several frames are used) is a device that permits access to population units. The frame population is the set of population units which can be accessed through the frame and the survey data really refer to this population of institutional units.
The objective of the European R&D statistics is to cover all intramural R&D activities. In line with this objective, the target population for the national R&D survey of the PNP Sector should consist of all R&D performing units (including known R&D performers or assumed to perform R&D). In practise however, countries in their R&D surveys might have difficulty in identifying R&D activities at the municipality level.
| Target population when sample/census survey is used for collection of raw data | Target population when administrative data or pre-compiled statistics are used | |
|---|---|---|
| Definition of the national target population | Target population of the PNP sector covers non-market, non-profit institutions serving households. | No administrative data or pre-compiled statistics were used. |
| Estimation of the target population size | All units known or supposed to perform R&D. The number of units in the target population for PNP was 18 legal units. | No administrative data or pre-compiled statistics were used. |
3.7. Reference area
Not requested. R&D statistics cover national and regional data.
3.8. Coverage - Time
Not requested. See concept 12.3.2. (data availability).
3.9. Base period
The base year for the unit Purchasing Power Standard (PPS) and PPS per inhabitant at constant prices is currently 2005. All calculations of non-basic unit (national currencies) are done by Eurostat.
R&D expenditure is published in the following units: Euro (MIO_EUR) and Euro per inhabitant (EUR_HAB); data are available in the following units: basic unit National currency (MIO_NAC); Purchasing Power Standard (MIO_PPS); Purchasing Power Standard at 2005 prices (MIO_PPS_KP05); Purchasing Power Standard per inhabitant at constant 2005 prices (PPS_HAB_KP05); Percentage of gross domestic product (PC_GDP); and Percentage of total R&D expenditure (PC_TOT - for the breakdown by source of funds).
R&D personnel data are published in full-time equivalent (FTE), in head count (HC), as a percentage of total employment and as a percentage of active population.
Calendar year 2023.
6.1. Institutional Mandate - legal acts and other agreements
See below.
6.1.1. European legislation
Legal acts / agreements:
Since the beginning of 2021, the collection of R&D statistics is based on the Commission Implementing Regulation (EU) No 2020/1197 of 30 July 2020 laying down technical specifications and arrangements pursuant to Regulation (EU) 2019/2152 of the European Parliament and of the Council on European business statistics repealing 10 legal acts in the field of business statistics. The Regulation sets the framework for the collection of R&D statistics and specifies the main variables of interest and their breakdowns at predefined level of detail. The transmission of R&D data is mandatory for Member States and EEA countries.
Commission Implementing Regulation (EU) No 2012/995 concerning the production and development of Community statistics on science and technology was in force until the end of 2020.
6.1.2. National legislation
| Existence of R&D specific statistical legislation | No |
|---|---|
| Are respondents obliged by the national law to provide raw and administrative data: | Yes |
6.1.3. Standards and manuals
- Frascati Manual 2015, Guidelines for Collecting and Reporting Data on Research and Experimental Development
- European Business Statistics Methodological Manual on R&D
6.2. Institutional Mandate - data sharing
Not requested.
7.1. Confidentiality - policy
A property of data indicating the extent to which their unauthorised disclosure could be prejudicial or harmful to the interest of the source or other relevant parties.
At the level of the ESS the EU regulation 223/2009 on European statistics defines confidential data as data which allows statistical units (respondents) to be identified, either directly - by formal identifiers such as respondents’ names, addresses, identification numbers - or indirectly - by using a combination of variables or characteristics such as age, gender, education - thereby disclosing individual information (see Article 2(1)(e) of regulation 223/2009).
At national level:
- Confidentiality protection required by law: Statistical data collected in this survey, according to the Official Statistics Act and Ordinance on Access to Confidential Data of the CBS within the System of Official Statistics is confidential and its purpose is restricted exclusively to statistical usage (with exception of registered researchers under specified conditions). Authorized interviewers are obligated to respect these restrictions. The results are published in a cumulative form which prevents displaying data on individuals.
- Confidentiality commitments of survey staff: According to Code of practice of European Statistics, all employees upon employment are informed of the rules and duties pertaining to confidential information and its treatment and are obliged sign statistical confidentiality statement.
7.2. Confidentiality - data treatment
Data are published in aggregated form which does not allow identification of the reporting unit. All collected data are confidential and are used only for statistical purposes.
The following rules are used to identify sensitive cells in tabular data:
- Threshold rule: The cell is considered sensitive if the cell frequency is less than a pre-specified threshold value. In practice this means if data in certain cell in the table relates to less than a pre-specified number of reporting units, the cell is primary sensitive.
- Dominance rule: The cell is considered sensitive if the value of 1 largest contributor in the cell exceeds a pre-specified percentage of total value for that cell.
When a data cell in a table is suppressed by dropping its value based on a primary cell suppression rule, the value of that cell can still be calculated if the table provides totals. Secondary cell suppression is therefore needed to avoid such disclosures. Those values under primary and secondary protection are therefore suppressed for use.
8.1. Release calendar
Release policy and release calendar are available and publicly accessible on CBS website.
8.2. Release calendar access
- For Eurostat this is: Release calendar - Eurostat (europa.eu)
- At national level this is: Calendar of Statistical Data Issues 2023 and Publishing Programme 2023.
8.3. Release policy - user access
According to the Release Date announced in the Publishing Programme and in the Calendar of Statistical Data Issues, publications of the Croatian Bureau of Statistics are released at 11:00 a.m. precisely, thus abiding by the Principle of Timeliness of the European Statistics Code of Practice, i.e. standard daily time set for the release.
All users access the data at the precise time and no other users have access to data prior the release. Detailed breakdowns that are transmitted to Eurostat with a confidentiality flag are not disseminated nationally for confidentiality reasons. Due to small counts in Private-non profit sector, the data is nationally published summed with Government sector.
The frequency of R&D data dissemination at Eurostat level is yearly for provisional and final data.
At national level the frequency of R&D data dissemination is also yearly, at the beginning of November as First Release and at the beginning of July as PC-Axis data base.

|---|---|
| Requests on further clarification, most problematic issues | Users generally have no additional questions or requests for further clarifications. |
11.1. Quality assurance
At Eurostat level, the common quality framework of the European Statistical System (ESS) is composed of the European Statistics Code of Practice, the Quality Assurance Framework of the ESS, and the general quality management principles (such as continuous interaction with users, continuous improvement, integration, and harmonisation).
Croatian Bureau of Statistics uses the model of total quality management which comprises European Code of Practice. In order to ensure this, a quality system has been established. The CBS regularly submits quality reports according to the templates prescribed for each area of statistics by the corresponding organizational unit of Eurostat. A template was developed based on the ESMS, ESQRS and SIMS structures. In order to produce complete reports on quality, considering all quality indicators, the CBS has prepared a Manual for the calculation of quality indicators. Quality reports for individual statistical surveys are available on the website of the CBS.
The POMI quality database offers many opportunities as well as DESAP questionnaire for doing self-assessment. As already mentioned before the developed tools like POMI quality and application database in combination with the GSBPM give the opportunity for each statistical survey to be improved if necessary. An independent Internal Audit unit conducts internal audits in the CBS, gives professional opinion and has an advisory role for improving CBS business operation, estimate systems, processes and the internal controlling system based on the risk management, carries out internal audits in accordance with the best professional practice and internal audit standards in line with the International standards on internal auditing and the Ethics Code of the Internal Auditors.

Quality Report for Statistical Survey Research and Development for 2023
11.2. Quality management - assessment
In the period between data collection and the beginning of the statistical analysis based on the obtained statistics, data have to be processed in a certain way. The data collection instrument is an electronic questionnaire in Excel with embedded controls and notes on methodology. Additional controls have been introduced with regard to the collection of primary data, which, along with repeated contacting of reporting units, had the effect of reducing the non-response rate for certain items. The switch to electronic data collection improved data processing, data editing and tabulation. A part of data verification procedures is built in the Excel questionnaire, while other rules are defined in the expert unit, which also corrects existing errors found on the material and, if necessary, contacts reporting units to get complete and accurate data. It is not possible to set too many data verification procedures into the form itself; instead, after obtaining all reports from the field, data are entered into the Survey Processor in which they are then processed based on the prepared project request.
Timeliness of final results is T + 11 months. Data were released 15 days after the planned deadline according to the Calendar of Statistical Data Issues 2024.
For the reference year 2023 we improved the survey coverage which enabled us to identify unknown R&D performing units. The sources we have used are explained in section 2.1. Data description. The analysis of the mentioned sources resulted in adding 1 unit to the basic list of PNP reporting units. Total PNP population was 18 units.

| Cross-classification | Unit | Frequency |
|---|---|---|
| Yes | both HC and FTE | annual |
13.1. Accuracy - overall
Accuracy in the statistical sense denotes the closeness of computations or estimates to the exact or true values. Statistics are not equal with the true values because of variability (the statistics change from implementation to implementation of the survey due to random effects) and bias (the average of the possible values of the statistics from implementation to implementation is not equal to the true value due to systematic effects).
Several types of statistical errors occur during the survey process. The following typology of errors has been adopted:
- Sampling errors. These only affect sample surveys. They are due to the fact that only a subset of the population, usually randomly selected, is enumerated.
- Non-sampling errors. Non-sampling errors affect sample surveys and complete enumerations alike and comprise:
-
- Coverage errors,
- Measurement errors,
- Non response errors and
- Processing errors.
Model assumption errors should be treated under the heading of the respective error they are trying to reduce.
13.2. Sampling error
That part of the difference between a population value and an estimate thereof, derived from a random sample, which is due to the fact that only a subset of the population is enumerated.
13.2.1. Sampling error - indicators
Confidence interval for Total R&D expenditure: Not applicable, no sampling was used.
Confidence interval for Total R&D personnel (FTE): Not applicable, no sampling was used.
13.3. Non-sampling error
Non-sampling errors occur in all phases of a survey. They add to the sampling errors (if present) and contribute to decreasing overall accuracy. It is important to assess their relative weight in the total error and devote appropriate resources for their control and assessment.
- Extent of non-sampling errors: Not applicable.
- Measures taken to reduce the extent of non-sampling errors: Not applicable.
- Methods used in order to correct/adjust for such errors: Not applicable.
13.3.1. Coverage error
Coverage errors are due to divergences between the target population and the frame population. The frame population is the set of target population members that has a chance to be selected into the survey sample. It is a listing of all items in the population from which the sample is drawn that contains contact details as well as sufficient information to perform stratification and sampling.

14.1. Timeliness
Timeliness and punctuality refer to time and dates, but in a different manner: the timeliness of statistics reflects the length of time between their availability and the event or phenomenon they describe. Punctuality refers to the time lag between the release date of the data and the target date on which they should have been delivered, with reference to dates announced in the official release calendar.
14.1.1. Time lag - first result
Time lag between the end of reference period and the release date of the results:
Indicator: (Release date of provisional/ first results) - (Date of reference for the data)
- End of reference period: 31 December 2023
- Date of first release of national data: 15 November 2024
- Lag (days): 320
14.1.2. Time lag - final result
- End of reference period: 31 December 2023
- Date of first release of national data: 15 November 2024
- Lag (days): 320
14.2. Punctuality
Punctuality refers to the time lag between the release date of data and the target date on which they were scheduled for release as announced officially.
14.2.1. Punctuality - delivery and publication
Punctuality of time schedule of data release = (Actual date of the data release) - (Scheduled date of the data release)
14.2.1.1. Deadline and date of data transmission
| Transmission of provisional data | Transmission of final data | |
|---|---|---|
| Legally defined deadline of data transmission (T+_ months) | 10 | 18 |
| Actual date of transmission of the data (T+x months) | 11 | 18 |
| Delay (days) | 15 | 0 |
| Reasoning for delay | late responses of large enterprises with considerable amounts of R&D expenditure | no delay |

15.3. Coherence - cross domain
See below.
15.3.1. Coherence - sub annual and annual statistics
Not requested.
15.3.2. Coherence - National Accounts
The changes in the new European system of national accounts ESA 2010 resulted for R&D to be classified as fixed assets, meaning the cost of producing of R&D or acquisition cost of R&D are recognized as gross fixed capital formation. Prior to these changes, expenses related to R&D were classified as intermediate consumption, but recognition of R&D contributing to productivity lead to the conclusions that such costs should be recorded as fixed assets.
The main data sources for R&D estimates in Croatia are annual reports collected from legal entities dealing with R&D in the reference year (forms IR-1, form IR-2 and form IR-3). These reports have been carried out on the basis of the international methodology – the Frascati Manual of OECD. Beside the statistical reports on R&D, the main administrative data for estimating GDP (Annual financial reports of entrepreneurs) have also been used. For the data on imports of R&D, the balance of payments has been used.
15.4. Coherence - internal

15.4.2. Consistency between R&D personnel and expenditure
| Average remuneration per year (cost in national currency) | Explanation of consistency issues if any |
|
|---|---|---|
| Consistency between FTEs of internal R&D personnel and R&D labour costs (1) | 23 498 euro | There is no consistency issues. |
| Consistency between FTEs of external R&D personnel and other current costs for external R&D personnel (2) | 19 430 euro | There is no consistency issues. |
(1) Calculate the average remuneration (cost) of individuals belonging to the internal R&D personnel, excluding those who are only formally ‘employees’ (university students, grant holders, etc.).
(2) Calculate the average remuneration (cost) of individuals belonging to the external R&D personnel (FTEs/other current R&D costs for external R&D personnel).
The assessment of costs associated with a statistical product is a rather complicated task since there must exist a mechanism for appointing portions of shared costs (for instance shared IT resources and dissemination channels) and overheads (office space, utility bills etc). The assessment must become detailed and clear enough so that international comparisons among agencies of different structures are feasible.

18.1. Source data
Several separate activities are used for the collection of raw data or pre-compiled administrative data and statistics related to R&D. This section collects information on the type of data collection instruments used as well as methodological information for each data collection instrument. Depending on the type of data collection instrument used, only the sections corresponding to that data collection instrument are filled in.
18.1.1. Data source – general information
The Research and Development survey is an annual census survey. Data are the result of statistical processing of annual reports collected from legal units dealing with R&D in the Republic of Croatia in the 2023 calendar year. The units from private non-profit sector filled out the Annual Report on R&D for Government and Private Non-Profit Sector (IR-2 form). The forms were sent to the reporting units via electronic mail, along with general instructions and attachments required to fill out the forms. The reporting units returned the completed forms in the same way.

18.4. Data validation
Source data are checked by means of visual control (checking if all requested data are filled in, checking for logical or numerical inconsistencies - within a single table and several tables of the questionnaire). In case of incomplete, illogical or incorrect answers, we contact the respondents. Reported data are then compared with previous cycles, and in case of larger discrepancies we contact the respondents in order to verify the reported data. We compare data on employed personnel and R&D expenditures with data in the statistical business register. Even though Excel questionnaires have built-in controls to decrease data entry errors, each report is additionally checked in Survey Processor application. Aggregated data are checked again for inconsistencies and outliers.

Statistics on Private non-profit R&D (PNPRD) measure research and experimental development (R&D) performed in the private non-profit sector, i.e. R&D expenditure and R&D personnel. In line with this objective the target population for the national R&D survey of the private non-profit sector should consist of all R&D performing units (including all R&D performers – occasional and continuous, known and unknown - in all branches and size classes) belonging to this sector.
The main concepts and definitions used for the production of R&D statistics are given by the OECD (2015), Frascati Manual 2015: Guidelines for Collecting and Reporting Data on Research and Experimental Development, The Measurement of Scientific, Technological and Innovation Activities, which is the internationally recognised standard methodology for collecting R&D statistics and by Eurostat’s European Business Statistics Methodological Manual on R&D Statistics (EBS Methodological Manual on R&D Statistics)..
The guiding document to preparing the quality reports is the European Statistical System (ESS) Handbook for Quality and Metadata Reports — re-edition 2021.
Since the beginning of 2021, the collection of R&D statistics is based on Commission Implementing Regulation (EU) No 2020/1197 of 30 July 2020. The Regulation sets the framework for the collection of R&D statistics and specifies the main variables of interest and their breakdowns at predefined level of detail.

The statistical unit is the institutional unit as defined by Council Regulation (EEC) No 1993/696 of 15 March 1993. There are no deviations.
In PNP, the statistical unit is legal unit.

Calendar year 2023.
Accuracy in the statistical sense denotes the closeness of computations or estimates to the exact or true values. Statistics are not equal with the true values because of variability (the statistics change from implementation to implementation of the survey due to random effects) and bias (the average of the possible values of the statistics from implementation to implementation is not equal to the true value due to systematic effects).
Several types of statistical errors occur during the survey process. The following typology of errors has been adopted:
- Sampling errors. These only affect sample surveys. They are due to the fact that only a subset of the population, usually randomly selected, is enumerated.
- Non-sampling errors. Non-sampling errors affect sample surveys and complete enumerations alike and comprise:
-
- Coverage errors,
- Measurement errors,
- Non response errors and
- Processing errors.
Model assumption errors should be treated under the heading of the respective error they are trying to reduce.
R&D expenditure is published in the following units: Euro (MIO_EUR) and Euro per inhabitant (EUR_HAB); data are available in the following units: basic unit National currency (MIO_NAC); Purchasing Power Standard (MIO_PPS); Purchasing Power Standard at 2005 prices (MIO_PPS_KP05); Purchasing Power Standard per inhabitant at constant 2005 prices (PPS_HAB_KP05); Percentage of gross domestic product (PC_GDP); and Percentage of total R&D expenditure (PC_TOT - for the breakdown by source of funds).
R&D personnel data are published in full-time equivalent (FTE), in head count (HC), as a percentage of total employment and as a percentage of active population.
See below.
Several separate activities are used for the collection of raw data or pre-compiled administrative data and statistics related to R&D. This section collects information on the type of data collection instruments used as well as methodological information for each data collection instrument. Depending on the type of data collection instrument used, only the sections corresponding to that data collection instrument are filled in.
The frequency of R&D data dissemination at Eurostat level is yearly for provisional and final data.
At national level the frequency of R&D data dissemination is also yearly, at the beginning of November as First Release and at the beginning of July as PC-Axis data base.
Timeliness and punctuality refer to time and dates, but in a different manner: the timeliness of statistics reflects the length of time between their availability and the event or phenomenon they describe. Punctuality refers to the time lag between the release date of the data and the target date on which they should have been delivered, with reference to dates announced in the official release calendar.
