3.1. Data description

PRODCOM is an annual survey conducted by Statistics Estonia. The industrial production data for Estonia is collected applying nationally adjusted (which is made more detailed for the national users) Prodcom list called  TTL . It is carried out in compliance with EU Council Regulation on the Establishment of a Community Survey of Industrial Production (No.3924/91).

The PRODCOM survey provides information on PRODuction of the European COMmunity and is compiled from data received from Estonian manufacturers. Generally the respondents are enterprises with 10 or more employees, whose primary or secondary activity is manufacturing covering NACE 06-33. The survey sample covers approximately 2100 enterprises and nationally about 3900 products including also industrial services.

Data available include value and volume of sold production and volume of total production during the surevy period.

COVID-19 impact is not noticed to PRODCOM 2020 data collection

3.2. Classification system

Prodcom surevey is based on the classification called PRODCOM List, which is divided into “Classes” corresponding to the classes of NACE rev 2. Within the individual classes, the headings of the list are set out in ascending order of their PRODCOM codes. PRODCOM uses an eight-digit product code of the form XX.XX.XX.YY. The first four digits of the code correspond to the 4-digit classes of NACE Rev. 2. The first six digits are the Community Classification of Products by Activity (CPA) codes. The CPA provides a detailed listing of the characteristic products for each 4-digit NACE Rev. 2 economic activity. The last two digits provide a more detailed breakdown of the CPA classes into PRODCOM product headings. There is a direct link between the PRODCOM classification and the EU foreign trade Combined Nomenclature (CN). Each PRODCOM 8-digit heading covers one or more CN 8-digit headings.

At national level the classification is possible to view  List of industrial products , where is used 11-digit headings system.


3.3. Coverage - sector

The survey covers all industrial enterprises with ten or more persons engaged which are totally or primarily engaged in industrial production and industrial services in the Mining, Quarrying and Manufacturing industries (Nace Rev. 2 Sectors 06 - 33). As well are covered enterprises with 5–9 persons employed whose main or secondary activity is industry if coverage of the activity is less than 90% and all enterprises producing milk and ice-cream regardless of the number of persons employed.  Thus by the survey is covered 90 % of total Estonian production of NACE Rev.2 sections B and C. 



3.4. Statistical concepts and definitions

The purpose of the statistics is to report, for each product in the Prodcom List, how much has been produced in the reporting country during the reference year.

The following definitions are defined by Estonian statistical activity Manufactured goods and industrial services:

  • Manufactured goods: produced industrial products (including the ones found in the stock house) from own material or under sub-contracting on the territory of Estonia during the calendar year.
  • Industrial services: industrial services carried out on the territory of Estonia during the calendar year (services according to the Prodcom list or taken into use due to the national needs).
  • Sub-contracting: production of goods from the principal’s material, fee received.

Variables gathered using the statistical report:

  • Produced volume: produced national production generally using the measurement unit provided by the Prodcom list
  • Sold volume: sold national production generally using the measurement unit provided by the Prodcom list
  • Sold value: sold national value (euros)
  • Sold value under sub-contracting: sold national value (euros) produced from the principal´s material
  • Exported sold value: sold national value (euros) outside from Estonia
3.5. Statistical unit

Though we use the Legal Unit as observation unit, we only count in the industrial realisation whether mainly or secondarily activity of the legal unit is industry.

Like in short term statistics the statistical unit KAU is used for the production of PRODCOM statistics

3.6. Statistical population

The survey population is made up of all industrial enterprises in NACE 06-33 with 10 and more persons employed whose main or secondary activity is industry; enterprises with 5–9 persons employed whose main or secondary activity is industry if coverage of the activity is less than 90%; enterprises producing milk and ice-cream regardless of the number of persons employed

3.7. Reference area

Estonia the whole national territory

3.8. Coverage - Time

The period observed is one calendar year. Estonian industrial products statistics date back to the year 1940.

11. Quality management Top
11.1. Quality assurance

The quality of statistical information and its production process is ensured by the provisions of the European Statistics Code of Practice. The surveys in Statistics Estonia apply the quality document for Estonia official statistics Quality Policy of Statistics Estonia.

PRODCOM survey is based on annual information. PRODCOM data is checked in several ways:

  a) PRODCOM data are produced in close cooperation with STS, enabling the data reported in the two surveys to be checked against each other

  b) PRODCOM data are compared to foreign trade and customs statistics

  c) PRODCOM data are compared with SBS data

PRODCOM staff applies its own data checks by comparing unit values across enterprises and across time. Any identified outliers are reported to the declarant, asking an explanation or a correction.

11.2. Quality management - assessment

Statistics Estonia performs all statistical activities according to an international model (Generic Statistical Business Process Model – GSBPM). According to the GSBPM, the final phase of statistical activities is overall evaluation using information gathered in each phase or sub-process; this information can take many forms, including feedback from users, process metadata, system metrics and suggestions from employees. This information is used to prepare the evaluation report which outlines all the quality problems related to the specific statistical activity and serves as input for improvement actions

Industrial products statistics data are collected via electronic system. Questionnaire and collecting system provide a number of arithmetic and logical controls, both mandatory and optional between the items in each form and between the forms in the whole annual report. There are a number of arithmetic and logical controls inside the questionnaire. The questionnaire cannot be filled-in successfully before all errors inside the questionnaire, detected by the checking program, have been corrected. 

12. Relevance Top
12.1. Relevance - User Needs

   • DG Growth (the policy arm of the Commission regarding the business sector) - measurement and monitoring of the policy agenda, especially the Lisbon targets.

   • Other directorates (DG TRADE, COMP, MARKT, etc) (policy setting) - needs in terms of statistics is various, especially in the business domains.

   • Other ESTAT Units:

       - Environmental statistics and accounts - statistics on products such as hazardous chemicals, products whose manufacture emits greenhouse gases and other products with an environmental impact.

       - Food safety statistics - monitor the manufacture of food and beverages.

   • EU Enterprises and EU Trade Associations (national administrations) - international comparisons.

   • The public (research institutions, students, media) - varied, mainly intra EU comparisons.

12.2. Relevance - User Satisfaction

Since 1996, Statistics Estonia has conducted reputation and user satisfaction surveys.


12.3. Completeness

13. Accuracy Top
13.1. Accuracy - overall

ACCURACY - Accuracy, in the general statistical sense, denotes the closeness of computations or estimates to the exact or true values.


Sampling issues relevant for PRODCOM surveys

Target population

The target population covers all enterprises which manufacture at least one product included in the PRODCOM List. The link with the NACE classification is used to identify the enterprises which are most likely to manufacture products included in the PRODCOM List.

The PRODCOM regulation states that all EU enterprises which carry out one of the activities in "Mining and Quarrying" and "Manufacturing", (i.e. sections B and C of NACE Rev. 2) should be covered by the PRODCOM survey.

Sampling frame

The Statistical Business Register (SBR) is the source for drawing and maintaining the sampling frame of the PRODCOM survey. The sampling frame of the PRODCOM survey includes all enterprises, authorities and organizations that carry out any target industrial activity and have 20 employees or more.

In Estonia generally the respondents are legal units with 10 and more persons employed, whose primary or secondary activity is manufacturing. In exceptional cases legal units with less than 10 persons employed are included into the survey.

Though we use a legal unit as an observation unit, we only count in the industrial realization whether the activity of the legal unit is mainly or secondarily industry. In another words it could be interpreted as a KAU.

Sampling design

The national sample of enterprises has to be designed in such a way that it leads to representative results of the national economy level and of each product included in the PRODCOM List (i.e. heading level).

In undertaking the PRODCOM survey, there are three conditions to be met:

- in each Member State at least 90% of production in each (four-digit) NACE class must be recorded;

- all enterprises of  20 or more employees in Sections B and C of NACE Rev. 2 should be covered;

- if a Member State’s production in a NACE class represents less than 1% of the Community total for that NACE class, then data for the headings in that class does not need to be collected.

In 2020, the response rate was of 73,6 % of all enterprises surveyed.

13.2. Sampling error

Not applicable

13.3. Non-sampling error

The missing data are estimated by using alternative administrative sources or other statistical surveys, mainly SBS. In other cases where is not possible to estimate the missing volumes, the Eurostat Median Price is used to obtain unit price. Errors of respondents are checked, mistakes are corrected on primary level of data. In order to provide complete data, the missing data are imputed. Non-response rate in 2019 26,4%, imputation rate 9,0%.

14. Timeliness and punctuality Top
14.1. Timeliness

According to the PRODCOM Regulation, Art. 7, "Member States shall send the findings relating to a one-year period to the Statistical Office of the European Communities within six months after the end of the reference year", which means that preliminary data is published 180 days after the end of the reference year (T + 180) and final data is published 360 days after the end of the reference year (T + 360).

14.2. Punctuality

The data have been published at the time announced in the release calendar

15. Coherence and comparability Top
15.1. Comparability - geographical

The data are comparable with the data of other European Union (EU) countries, because a common methodology is used for data collection and release. All EU countries produce PRODCOM statistics, which is the system for the collection and dissemination of statistics of industrial goods based on the PRODCOM List (8-digit codes). In Estonia, the List of Estonian Products (TTL) is used, which is based on the PRODCOM List and has 11-digit codes, with Estonian codes added according to the interest of users (oil shale).
Eurostat database includes sold production volume and value and total production volume. Statistics Estonia’s database includes only sold production volume and value; total production is not published.


15.2. Comparability - over time

The data are comparable since year 2000

The data for 2000–2007 have been recalculated according to the new version of the Statistical Classification of Economic Activities NACE Rev. 2 (Estonian Classification of Economic Activities 2008 (EMTAK 2008)).
Due to changes resulting from the revision of the international product classification of the Harmonized System (HS) every five years, there are significant changes also in the Combined Nomenclature (CN) and PRODCOM List. The classification PRODCOM List is updated each year, and accordingly also the List of Estonian Products (TTL). Due to annual changes and updates, the time series are not comparable for all codes.

15.3. Coherence - cross domain

The data are comparable with: 1) the data for turnover of industrial production collected with the annual EKOMAR questionnaire (SBS, structural business statistics); 2) data collected for product categories oil shale, peat and wood processing products using the short-term business statistics (STS) questionnaires (industry (monthly), energy and fuel); 3) the data of total exports by enterprise and country collected with the foreign trade in goods monthly questionnaire. To ensure data accuracy, comparability checks are run against SBS and STS data.

15.4. Coherence - internal

17. Data revision Top
17.1. Data revision - policy

The data revision policy and notification of corrections are described in the dissemination policy of Statistics Estonia


17.2. Data revision - practice

The published data may be revised if the methodology is modified, errors are discovered, new or better data become available

18. Statistical processing Top
18.1. Source data

Statistics are collected by non-probability sampling which means that it is a full coverage survey with a cut-off threshold (i.e. cut-off sample).

Generally the respondents are enterprises with 10 and more persons employed, whose primary or secondary activity is manufacturing.

18.2. Frequency of data collection


18.3. Data collection

Data are collected and the submission of questionnaires is monitored through eSTAT (the web channel for electronic data submission). The questionnaires have been designed for independent completion in eSTAT and include instructions and controls. The questionnaires and information about data submission are available on Statistics Estonia’s website at

Data are collected with the official statistics annual questionnaires “Tööstustooted” (Industrial Products) and “Tööstus- ja piimatooted” (Industrial and dairy products).

18.4. Data validation

The validation process consists of arithmetic and quality checks, incl. comparison with other data. Before data dissemination their internal coherence is checked

18.5. Data compilation

Data is collected according to the list of industrial products based on the international classification List of Products of the European Community (Prodcom list). In the case of missing or unreliable data, imputation is used, for example by using administrative sources.

18.6. Adjustment

Not applicable
