The National Statistics Institute has carried out the Libraries Statistics since 1959. Since 1986, it has been developed biennially.
The statistic provides information both on activity (stock, visitors, loans...) and the libraries' structural characteristics (type of libraries, infrastructure and equipment, staff, financing, form of access,…). The classification variables are the type of library and the Autonomous Community in which it is located.
This statistic measures the biennial variations in libraries and facilitates international comparability, which is carried out through the completion of questionnaires from international bodies (UNESCO, Eurostat, IFLA).
The research extends to all libraries in Spain, with the exception of school and private libraries that the public cannot use, even in special circumstances.
This statistic is prepared on the basis of UNESCO recommendations in relation to the definitions(library , service point, fund, loan, expenditure) and classifications(library type, theme) that appear in the Recommendation concerning the International Standardisation of Library Statistics, approved by the General Conference of UNESCO at its sixteenth session in 1970.
From 2002, some changes were introduced, such as the use of a new definition of a library based on the standard ISO 2789
This operation extends to all kinds of libraries, thus, it covers almost all institutional sectors:
- Public Sector: National Library, Central Libraries of Autonomous Communities, Public Libraries(public access), Libraries of Public Institutions of Higher Education, or specialised libraries of the Public Sector (such as libraries belonging to the Administration, to public businesses or research and archive centres and museums or public health facilities).
- Private Sector: Such as Private Institutions of Higher Education, or specialised private sector libraries (such as libraries of commercial businesses or firms, of professional associations or bodies, or of research and archive centres and museums or private health facilities)
- Private Non-Profit Institution libraries, such as those of religious institutions.
The Statistical Unit of this operation is the Library, as Administrative Unit.
To collect the information, each of these is contacted, through a cover letter that includes the website address of a custom application for the completion of the questionnaire, as well as the access codes to this application.
This statistical research covers all libraries, regardless of their administrative dependence
with the exception of:
private libraries (of individuals or businesses) that the public cannot use even in special circumstances, and school libraries
The research covers the entire Spanish territory
The research is carried out biennially.
The latest results refer to 2018.
The statistic's reference period is the calendar year (2018), although for some factors information is requested on the situation to 31 December of the year in question.
This statistical operation was stopped by the INE in the year 2018, with the publication of the reference period 2018. Its elaboration from that moment on was assumed by the Ministry of Culture
This statistical operation has been carried out since 1959.
With regards to the previous classifications, from 2012, changes were introduced such as the use of a new definition of library based on the standard ISO 2789, a new classification of the types of libraries was established and research into the implementation of information and communication technology in libraries was carried out in greater depth.
Since 1990, a series on the number of libraries (as administrative units) has been published, along with the number of service points, available at:
Libraries: administrative unit (includes associated service points)
Equitment: number of devices
Funds: volumes / number or units depending on the type of fund
Expenditure: euros.
The data refer to the calendar year that is the object of the survey, except some of the questions that specifically request data for 31 December of that year.
The required information is for even-numbered years, and collected in odd-numbered years .
Data referred to the period: Estadistica de bibliotecas 2018.
The compilation and dissemination of the data are governed by the Statistical Law No. 12/1989 "Public Statistical Function" of May 9, 1989, and Law No. 4/1990 of June 29 on “National Budget of State for the year 1990" amended by Law No. 13/1996 "Fiscal, administrative and social measures" of December 30, 1996, makes compulsory all statistics included in the National Statistics Plan. The National Statistical Plan 2009-2012 was approved by the Royal Decree 1663/2008. It contains the statistics that must be developed in the four year period by the State General Administration's services or any other entity dependent on it. All statistics included in the National Statistics Plan are statistics for state purposes and are obligatory. The National Statistics Plan 2021-2024, approved by Royal Decree 1110/2020, of 15 December, is the Plan currently implemented. This statistical operation has governmental purposes, and it is included in the National Statistics Plan 2021-2024. (Statistics of the State Administration).
.
For the Libraries Statistics, collaboration agreements have been signed with the Statistical Institutions of some Autonomous Communities:
- Statistics Institute of Aragon.
- Statistics Institute of Catalonia.
- Statistics Institute of Navarra.
Through these collaboration agreements, these institutes use the INE's own resources to collect information in their respective Autonomous Communities, later carrying out their own statistical studies.
Furthermore, collaboration agreements have been signed with the Ministry of Defence and the Civil Guard in relation to the libraries in their scope.
On the other hand, at the time of publication, all Autonomous Communities have access to the information published through the INE archive.
In order to access the custom application for collecting the data for the Libraries Statistics, respondents have user codes and passwords specific to each user.
This allows for this statistic's questionnaire to be carried out completely securely and confidentially.
Furthermore, the application itself has an additional security mechanism; when approximately 20 minutes pass without any activity registered, the application is blocked and access to any of its sections is blocked. In order to access it again, the established codes should be used.
Once the questionnaire is completed and terminated, users will not be able to access it again, unless they explicitly request to do so. In this way, it will not be possible to make unwanted changes.
Once the questionnaires are reviewed by the collection units (the provincial delegations), the staff at these units will also not have access to make modifications.
Results are published biennially and in odd-numbered years.
The survey results are released through the INE's webpage.
The published information includes:
- the Survey Press Release.
- Detailed results from the last published year and previous years.
- the Survey Methodology
- Issues concerning the response rate
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.
Information on the latest publication of the Libraries Statistics can be found on INEbase/Society/Culture and Leisure section , or through the following INE webpage:
There is no direct access to this survey's microdata through the INE's website.
However, users can accessthem,under especial conditions, through custom requests.There is information in the following link:
Interested users can make requests, through the INE Information Area at:
, specific uses of custom information that are carried out whilst preserving confidentiality of the data in all cases.
Methodology:
A detailed description of the methodology can be found at:
https://www.ine.es/en/daco/daco42/cultocio/metobibli2012_en.pdf (*)
The questionnaire that was used to request information from the respondent units can be found at:
At the end of the questionnaire, all the concepts used are explained, with examples that aid completion of the questionnaire.
The questionnaire is translated into all of the State's co-official languages, to facilitate comprehension and to improve user satisfaction in the Autonomous Communities in which they are spoken.
User Manual of the custom application: To facilitate the completion of the questionnaire through the application, users of the application have a user manual at their disposal, which is translated into all of the State's co-official languages. The aforementioned manual can be found at:

Sections 10.6 to 17 of this document constitute the user-oriented quality report of this 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 territorial units of the INE (Provincial Delegations) are involved in the collection of information, along with the Statistics Institutes with which INE has an agreement, which allow a greater proximity to the respondent units (libraries). With this, an improved coverage control is guaranteed.
To facilitate the completion of the questionnaire by respondents, a custom application for collecting data for this operation has been designed, developed and introduced. The fact that respondents have this tool at their disposal has mainly positively influenced two aspects with regards to previous years.
- the quality of data has improved
- the response rate has improved
Once the questionnaire has been answered, validation controls and controls for the detection of inconsistencies are established, which are incorporated into the completion application. This means that in the first stage alone, the user themselves can detect and/or clarify those errors in the application itself. If these errors have been overlooked and/or they have not been satisfactorily explained, once they are detected by the collection units these may contact the respondent units to definitively clarify them.
Once the information is validated, the filtering and imputation process is carried out by the INE Central Services.
The information collection application has enabled both a quantitative improvement (higher response rates) and a qualitative improvement in the data collected in this statistic.
This application was implemented in 2009 for the collection of information referring to 2008.
The fact that this application includes validation controls and controls for the detection of inconsistencies, as well as having the close attention of the collection units, makes it possible for the accuracy and reliability of the data to be quite high.
The fact that the questionnaires are adapted to the norms of international bodies (UNESCO, Eurostat, IFLA) guarantees international coherence and comparability of the survey's information.
Users of the Libraries Statistics include:
- Autonomous Communities
- Users that make custom information requests
The INE has carried out general user satisfaction surveys in 2007, 2010, 2013 and 2016 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)
In the user satisfaction surveys carried out to date, the Society sector is valued, which includes the areas: Education, Culture, Health and Justice, in which this statistical operation is framed. The value of the user satisfaction index for this sector according to the ESU 2016 is 3.74 out of 5.
The information collected in this investigation allows for all established objectives to be fulfilled:
- All the information required by the NSP is collected
- The statistic enables the measuring of changes occurring in all dimensions (general data, equipment, stock, staff, etc.) of the libraries over a period of two years.
IndicatorR1=100%
The correct adaptation of MARCO means that the difference between the libraries toward which the investigation is aimed and those libraries toward which the investigation should be aimed is minimal.
As detailed in point 12 of this quality management report, the information collection, error detection and validation procedures of the questionnaires allow for the production of a statistic with a high level of reliability.
This statistical operation is exhaustive, therefore there are no sampling errors.
With regards to non-sampling errors, it is indicated that, as mentioned previously, as there is a well-formed framework coverage errors are rare.
To have this quality framework available, and to avoid those errors, a filtering process is carried out on the directory, as well as of the type of library of each one of the registers in the framework.
As has also been explained, this statistic has a high response rate. In fact, for the 2016 Libraries Statistics, the non-response rate was A4=2,8% .
However, an imputation in units with a non-response is carried out, to be able to adjust results better, and to avoid errors that could cause this non-response.
For more information, see:
The survey data are generally published at the end of the year following the reference year of the information, in other words, within TP2=12 months.
Data is released according to INE's structural statistics availability calendar, which INE prepares and publishes for each year.
A common collection, filtering and validation process throughout the national geographic scope, including in the Autonomous Communities whose own Statistics Institute carried out these processes, guarantees the comparability of the results between the different Autonomous Cities and Communities and between provinces.
On the other hand, as the statistic is adapted to the norms of international bodies, it is also prepared for international comparability.
The inclusion of new concepts to satisfy the need for information in regards to the inclusion of new technologies and new realities of libraries has not created a series break. Thus, this research can be compared to previous years' series.
Although this statistic has been carried out since 1959, the tabulated results have been available on the website since 2000.
There is also a series on the number of libraries and number of service points carried out by Autonomous Communities and Cities since 1990. The length of the series in December 2019 is CC2=15 elements.
The Libraries Statistics is coherent with publications that are developed by the Ministry of Culture and Sport.
Coherence between variables is compared at all stages of the statistical process. There are internal validation rules between them that ensure total coherence.
Although the burden on the respondent has not been reduced, the fact that there is a custom application for the statistic reduces the amount of time needed to complete the questionnaire, as well as producing a positive effect in terms of the respondent's perception of the ease of completing the survey.
The estimated budgetary appropriation needed to finance this statistic, as provided for the the 2018 and 2019 Annual Programmes, is a total of 78.32 thousand Euros.
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-.
There is no review of published data.
Not applicable
For the implementation of the Libraries Statistics, a collaboration agreement with the Ministry of Culture and Sport is maintained, which allows this Ministry to provide the directory of all libraries that exist on national territory to the Culture and Leisure area of INE's Sub-directorate General for Sectoral Social Statistics.
In the Autonomous Communities with which INE has a collaboration agreement, the corresponding statistics institutes are responsible for preparing an appropriate framework in collaboration with the relevant regional culture councils.
Information is collected every odd year, referencing the previous year.
In the year in which collection takes place, it is limited to a period of three months, usually between March and June.
Information is mainly collected through the application designed for this purpose.
To obtain the information, each respondent unit is contacted through a cover letter that includes the website address of the custom application for completing the questionnaires, as well as the access codes to this application.
If there are respondents who do not have an internet connection, or who prefer to use traditional collection methods, a paper questionnaire is sent to them that, once completed, they then send to their predetermined collection unit, where it is recorded using the application.
Moreover, there are agreements with the Statistics Institute of Catalonia, the Statistics Institute of Aragon ,the Statistics Institute of Navarra, and the Ministry of Defence that enable these bodies to collect data relating to libraries established in Catalonia, public libraries in Aragon and those dependent on the Ministry of Defence, respectively. When the data are properly validated, they are provided to INE in a file that is incorporated into the application.
In the first stage, data is validated in the information collection units (INE's Provincial Delegations or Autonomous Communities' Statistics Institutes with which there is a collaboration agreement).
Once this process is complete, the Promoter Unit carries out a new filtering of errors that have passed the first filtering.
Once the data have been validated,imputation processes are carried out if necessary.
Once this stage is completed, the definitive file with which the results can be prepared is made available.
Data are tabulated with the SAS programmes specifically designed for this purpose. The results obtained are presented in two types of tables, according to the classification variable considered: type of library and Autonomous Community.
Finally, the results tables are exhaustively reviewed as a preliminary step to their release.
