The Annual Industrial Products Survey provides detailed structural information on the industrial production carried out in the national territory.
The main objectives of the survey are the following:
- To have access to complete nd recent information on the different products in the industrial sector, providing results with a level of detail that makes it possible to study a broad selection of products, to analyse their markets and to study the evolution of their chronological series.
- To present information that is fully integratable with that corresponding to the data for foreign trade.
- To provide information integrated with the rest of the European Community countries, thanks to the application of common methodologies, with facilitates provision of useful, reliable, quick and detailed information for the management of the European Community market.
- To disseminate the annual industrial production information in the least possible time, approximately half a year after the end of the data reference year.
The information object of the survey is defined by means of the different economic activities that constitute the industrial sector (sections B-C-D) in accordance with the National Classification of Economic Activities (CNAE-09) and according to the European Industrial Classification PRODCOM, which includes the class E3832.
For reference years before 2021, the survey target population consisted of all industrial establishments belonging to companies with twenty or more employed persons, irrespective of whether or not the main activity of the company to which it belonged was industrial. The aim was to cover a significant percentage of the industrial sector (sections B-C-D) production in accordance with the National Classification of Economic Activities(CNAE-09), with the exception of: Extraction of anthracite, coal and lignite; extraction of crude petroleum and natural gas; extraction of uranium and thorium ores; extraction of peat; mining and quarrying support activities; processing of nuclear fuels; transport, distribution and trade of electrical energy and distribution and trade of gas by pipelines.
In specific sectors in which the production of establishments of companies with twenty or more employed persons was not representative of the total, establishments were also included of companies with fewer than 20 employed persons. The ultimate aim was to achieve a coverage that included all establishments representing approximately the 90% of the corresponding activity.
For reference year 2021 and onwards, the survey target population consists of all industrial establishments, irrespective of whether or not the main activity of the legal unit to which it belongs is industrial. It is covered the 100% of the industrial sector (sections B-C-D) production in accordance with the National Classification of Economic Activities(CNAE-09), as well as the class E3832, with the exception of: Extraction of anthracite, coal and lignite; extraction of crude petroleum and natural gas; extraction of uranium and thorium ores; extraction of peat; mining and quarrying support activities; processing of nuclear fuels; transport, distribution and trade of electrical energy and distribution and trade of gas by pipelines.
The basic observation and information unit for the survey is the industrial establishment.

INEbase is the system the INE uses to store statistical information on the Internet. It contains all the information the INE produces in electronic formats. The primary organisation of the information follows the theme-based classification of the Inventory of Statistical Operations of the State General Administration . The basic unit of INEbase is the statistical operation, defined as the set of activities that lead to obtaining statistical results on a determined sector or subject based on the individually collected data. Also included in the scope of this definition are synthesis preparation.
The survey results are available from 1993 on the INE website https://www.ine.es/en/, in INEbase in the section: Industry, energy and construction", subsection " Industry and Energy"

Industrial Products Survey
For this statistical operation, anonymised data files are not provided.
There is the possibility of requesting, via the User Services Area of the INE, specific made-to-order operations carried out taking into account the conditions of data confidentiality.
A detailed description of the methodology of the survey can be found at:
There is no documentation regarding quality for this statistical operation in particular. The fields 10.6 to 17 in this form constitute a quality report for the user-oriented operation.
Quality assurance framework for the INE statistics is based on the ESSCoP, the European Statistics Code of Practice made by EUROSTAT. The ESSCoP is made up of 16 principles, gathered in three areas: Institutional Environment, Processes and Products. Each principle is associated with some indicators which make possible to measure it. In order to evaluate quality, EUROSTAT provides different tools: the indicators mentioned above, Self-assessment based on the DESAP model, peer review, user satisfaction surveys and other proceedings for evaluation.
The Industrial Products Survey also has in place a preparation process designed to guarantee quality, both of information received and of results obtained from this.
There are validation checks in the electronic questionnaire that make it possible to rectify errors by the actual respondents, a filtering process in the collection units and a check from the preparation process vitually parallel to information collection making it possible to lighten the deadlines for correction of possible errors, to mitigate the burden on respondents by reducing the number of contacts to be made, and to guarantee the quality of the statistics.
This survey is conducted following the quality criteria contained in the European Statistics Code of Practice.
The following may be cited as being among the main strengths of this survey:
1) Rapid collection, analysis and publication of the results, such that publication of the latter is carried out within 6 months of the end of the reference period.
2) Since it is an ongoing survey, carried out since 1993, data may be comprehensively monitored, such that possible inconsistencies therein may be detected.
3) Data is checked, by comparing it with that obtainedby other surveys related to industrial activity (Industrial Companies Survey, Industrial Production Index, Industrial Price Index, Industrial Turnover Index)
4) In recent years an effort has been made to collect questionnaires online. In the survey referring to 2023, the 93.7% of them were collected by this way.
Survey users include:
- Ministries and other public bodies.
- Industria (Autonomous Communities).
- Internationa institutions (EUROSTAT, UN, FAO, etc.).
- Companies and business institutions.
- Researchers and universities.
- Individuals.
Each user has different needs in accordance with the destination and usefulness of the information that they need, which in many cases leads to the performing of made-to-measure operations.
The INE has carried out general user satisfaction surveys in 2007, 2010, 2013, 2016 and 2019 and it plans to continue doing so every three years. The purpose of these surveys is to find out what users think about the quality of the information of the INE statistics and the extent to which their needs of information are covered. In addition, additional surveys are carried out in order to acknowledge better other fields such as dissemination of the information, quality of some publications...
On the INE website, in its section Methods and Projects / Quality and Code of Practice / INE quality management / User surveys are available surveys conducted to date.(Click next link)
The specific needs of users are taken into account so long as methodology revisions are made to the survey, for the purpose of adapting the content thereof to those specific requirements of the users improving their degree of satisfaction
The demand for tailored information is often referred to a territorial disaggregation of the published data.
In the User Satisfaction Surveys carried out to date, the "Industry, energy and construction" sector, in which the statistical operation is framed is assessed, which can guide users' opinions about it.
User satisfaction surveys can be consulted at the following link from the INE website:
Specifically, for reference years before 2021, the survey base was the European Union Council Regulation (EEC) no. 3924/91 regarding the establishment of a European Community survey for industrial production (Prodcom Regulation). The legal base was supplemented by the European Commission Regulation (EC) no. 912/2004 regarding execution of the European Council Regulation.
For reference year 2021 and onwards, the survey base is the Regulation (EU) 2019/2152 of the European Parliament and of the Council of 27 November 2019 and the Commission Implementing Regulation (EU) 2020/1197 of 30 July 2020.
The requirements contained in said regulations are 100% satisfied. R1 = 100%
The survey is designed to obtain a high degree of reliability and accurancy in the data obtained.
The different processes that the survey undergoes, from its design through to obtaining end results (coverage, collection, error filtering, imputation of the lack of response, etc.), are aimed at obtaining the highest degree of statistical reliability.
For reference years before 2021, the survey was designed by the cut-off procedure. Since it was not based on probabilistic methods, sampling errors were not calculated.
For reference year 2021 and onwards, the survey is based on probabilistic methods and sampling errors are calculated.
As well as this, the coefficients of variation (CV) are calculated and published at the product level (10 PRODCOM digits).
For reference year 2023, the sampling error of the total production value is around 0'05%.
CV intervals (in %) | Data qualification |
0.01%-4.99% | A: Excellent |
5.0%-9.99% | B: Very good |
10.0%-14.99% | C: Good |
15.0%-24.99% | D: Acceptable |
25.0%-34.99% | E: Use with caution |
35.0% and above... | F: Unreliable data |
In the whole statistical process, checks are carried out on errors other than sampling errors.
For reference year 2023:
Over-coverage rate: A2=6.56%
Non response rate by unit: A4=7.02%
Imputation rate: A7=6.15%
The survey is published within 6 months after the end of the reference period (calendar year). Thus, the survey referring to 2023 will be published on 26 June 2024, in compliance with European regulations. TP2 = 6 months.
The results of the survey are published in accordance with the calendario de INE structural press release calendar established at the beginning of each year
https://www.ine.es/en/daco/daco41/calen_en.htm
The survey design allows comparability of data on an Autonomous Community level.
On a European level, compliance with the PRODCOM regulation allows comparability with the remainder of the countries, since the survey is carried out in a uniform way in all of them.
The Industrial Products Survey was first created with reference to year 1993 and its results are comparable in time, except for products that have undergone some change during that period, new products incorporated over the years and those that have ceased to be manufactured.
It should be borne in mind, however, that in 2009 there was a logical break in the series, as a result of the coming into force of the new National Classification of Economic Activities (CNAE-09), whereby the data for the 2 data series is as follows
1993 -2007 with products classified in accordance with the CNAE -93
2008 onwards with products classified in accordance with the CNAE -09
Nonetheless, if an equivalence has been published between the codes for 2007 and 2008 in which those products are shown whose equivalence between the 2 classifications is unmistakeable.
In the reference year 2021 there is another break in the series, due to the entry into force of the the Regulation (EU) 2019/2152 of the European Parliament and of the Council of 27 November 2019 and the Commission Implementing Regulation (EU) 2020/1197 of 30 July 2020. For the reference year 2021, data under the old and new regulation are provided.
Number of comparable elements in the serie: CC2 = 3.
The data provided by the survey is consistent with foreign trade statistics.
From a sector point of view, there is a high degree of consistency between production in large sectors (motor, chemical industry, etc.) with the results provided by the actual sectors.
There is also great consistency with other statistics in the industrial sector, compiled by the INE (Industrial Companies Survey, Industrial Production Index, Industrial Price Index and Turnover Index)
Results have complete internal consistency, since it is a survey in which data used for obtaining this undergo the same processsed, analysis, validation and imputation.
The estimate of the budgetary credit necessary for financing these statistics, provided for in the 2024 annual is 1,271.45 thousand euros.
The workload for industrial establishments from which information is requested has seen a decrease over recent years with the implementation of a system to allow respondents to answer online, which, in tandem with the possibility of using other means such as email, fax or telephone for responding, has reduced the time and effort that the respondent must set aside in order to complete the questionnaire.
For reference year 2021 and onwards, with the new sampling design, the sample size has approximately been reduced by 30%, that means a significant reduction in the respondents burden.
The INE of Spain has a policy which regulates the basic aspects of statistical data revision, seeking to ensure process transparency and product quality. This policy is laid out in the document approved by the INE board of directors on 13 March of 2015, which is available on the INE website, in the section "Methods and projects/Quality and Code of Practice/INE’s Quality management/INE’s Revision policy" (link).
This general policy sets the criteria that the different type of revisions should follow: routine revision- it is the case of statistics whose production process includes regular revisions-; more extensive revision- when methodological or basic reference source changes take place-; and exceptional revision- for instance, when an error appears in a published statistic-.
Preview results are not disseminated; it is followed the general INE revision policy when is it is detected an error in the previous year "t" when it is published the year "t + 1" in any of the surveyed establishments.
N/A
Survey data is obtained from the questionnaires completed by industrial establishments.
For reference years before 2021, the target population consisted of all industrial establishments (regardless of the main activity of the company to which they belonged) necessary to cover approximately 90% of the production for each class, to four digits, of the National Classification of Economic Activities (CNAE –09).
For reference year 2021 and onwards, the survey target population consists of all industrial establishments, irrespective of whether or not the main activity of the legal unit to which it belongs is industrial.
The information studied by the survey is defined by means of the list of PRODCOM (PRODuccion COMunitaria [COMmunity PRODuction]) products that coincide with those corresponding to the different economic activities constituting the industrial sector in accordance with CNAE-09.
The PRODCOM list is updated annually, by incorporating or deleting products, amending the definitions of others, etc. The list is made up of approximately 4,000 products.
Data is collected annually (between the months of January and March in the year following the reference year).
Respondent establishments send data online (more than 90%); by regular post (questionnaires completed on paper), fax or email.
In the online survey completion phase, an inconsistency detection system is used, such that the respondent may confirm the information provided.
The recording of questionnaires is carried out continuously by the same collection units establishing the necessary control to guarantee an appropriate quality level for the whole process. This facilitates controlling, already in this phase, the errors that may affect the data obtained from respondent units.
Once information is received, a coverage check thereof is carried out in order to guarantee completeness of the recorded data, to detect duplicates and coverage errors, at the same time being able to make a first assessment of the quality of the variables obtained from the questionnaires. This phase is carried out on every fortnightly file from recorded questionnaires, and it is performed prior to compilation of the complete survey file, and therefore at the beginning of the joint information treatment.
The information, which has been received and filtered in an initial phase by the collection units, is treated at the INE by means of a two-phase filtering procedure:
The first phase consists of micro-filtering or filtering in which validy of the data facilitados por cada establecimiento is checked, such that possible errors or omissions may be detected.
The second phase consists of aggregate data fitering or macro-filtering on a national level, in order to analyse consistency of the data for each product and its evolution over time.
No seasonal adjustments are made.
