- 3.1Data description
Employment of persons with disabilities (EPD):
Periodic annual operation whose objective is to investigate the situation with respect to the labour market of the group of persons with disabilities aged between 16 and 64 years old.In particular, it is a question of estimating the number of persons with disabilities employed, unemployed and inactive, disaggregated by sex and impairment.
In addition, complementary objectives are derived such as:
- To obtain the personal, family and geographical characteristics of persons with disabilities in relation to the type and intensity of the disability.
- To compare the employment status of persons with disabilities with that of persons without disabilities.
- To analyse the impact of policies aimed at the group of persons with disabilities, both in terms of protection and promotion of employment.
- To study the evolution of the employment status of this group.
- 3.2Classification system
- Clasificaciones utilizadas
IMPAIRMENT
In 1991, IMSERSO implemented a new form of classification of impairments, adapting to the information demanded and to the contents of the evaluation reports. The objective is to record in the State Database of Persons with Disabilities (BEPD) the impairments that gave rise to the disability (impairment codes). The impairment codes used are specified in the EPD methodological manual (https://www.ine.es/dyngs/INEbase/en/operacion.htm?c=Estadistica_C&cid=1254736055502&menu=metodologia&idp=1254735976595). The following groupings of disability typology according to impairment are considered:
- Physical and others:
Osteoarticular systemNeuromuscular systemCardiovascular, Immune and Respiratory SystemsDigestive, Metabolic and Endocrine SystemsOthersIntellectual
Mental
- Sensory:
Visual SystemHearing systemDEGREE OF DISABILITY
The population is divided into two categories according to the percentage of degree of disability:
- Less than 33%
- 33% and moreFor EPD, only registers of persons with a degree equal to or greater than 33% and similar have been considered (according to Royal Legislative Decree 1/2013).
45% and 65% are disability grades that establish limits for the purpose of receiving pensions or granting early retirement.
For the purposes of tabulation, the following classification will be considered for the variable degree of disability:- from 33% to 49%
- from 50% to 64%
- from 65% to 74%
- 75% and above
ACTIVITY STATUS
Derived from the EAPS definitions, for EPD the working age population (16 to 64 years) is classified in:
- Economically active persons
- Employed persons
- Salaried employed persons
public sector
private sector
- Self-employed persons
Employers
Self-employed without employees and freelance workers
Cooperative members
Contributing family workers- Others
- Unemployed
- first-time job seekers
- who have worked before- Inactive
- Students- Retirees or pensioners- Housekeeping- Unable to work- Other status (renters,...)OCCUPATION
Prior to 2011, results are provided according to NCO-94. As of 2011 it is codified according to NCO- 11.
The activity sectors based on CNAE-09 are considered:
- Agriculture
- Industry
- Construction
- Services
EDUCATION (level of studies)
The following categories based on CNED -2014 are considered:
- Illiterates (code 80 of CNED-2014)
- Primary or lower education (codes 02-10)
- Secondary education, training programmes and labour insertion (codes 21-41)
- Higher studies and doctorate (codes 51-81)
- Clasificaciones utilizadas
- 3.3Sector coverage
Population coverage: Persons aged between 16 and 64 and residents in households (excluding collective dwellings)
Coverage by degree of disability: Degree greater than or equal to 33% and similar (according to Royal Legislative Decree 1/2013).
The coverage by impairment, branches of activity, occupation and level of studies is complete.
- 3.4Statistical concepts and definitions
- Disability certificate
- Impairment
Any organic or functional disorder giving rise to a disability.
- Dependency
Dependency is taken to mean the permanent status of persons who, for reasons deriving from age, illness or disability, and associated with the lack or loss of physical, mental, intellectual or sensory autonomy, require care from (an)other person(s) or significant assistance performing simple, everyday activities or, in the case of persons with learning difficulties or mental illness, other support for their personal autonomy.
- Disability
According to ICF, disability means the situation resulting from the interaction between the health condition and the contextual factors restricting the participation of the person (definition based on the International Classification of Functioning, Disability and Health (ICF) of the World Health Organisation).
- Measures to encourage employment
One way of offsetting the negative trends of the group's situation, in terms of economic activity, are measures aimed at promoting their inclusion within ordinary employment, favouring the hiring, particularly as permanent staff, of persons with disabilities and promoting their ongoing employment.
Among said measures, worth noting were reductions and discounts in contributions, both for wage earners and for self-employed workers.
With regard to salaried employees there is another measure that promotes ordinary employment: the modality of the specific contract for workers with disabilities in which, in addition to discounts in Social Security contributions, certain subsidies are considered. - Employees
Employees are all those persons aged over 16 years old who, during the reference week were employed by others, wage-earners, or performed freelance work pursuant, freelance workers.
- Unemployed persons
All those persons aged over 16 years old who, during the reference week were:
a) out of work, in other words, they had no paid employment or freelance work,
b) available for work, in other words, available to carry out a job as an employee or freelance work within the two weeks following the reference week,
c) actively jobseeking during the month prior to the Sunday of the reference week.
Persons are also considered unemployed when they are out of work but are about to start a new job within the three months subsequent to the reference week and are currently available for work. Therefore in this case it will not be necessary to demand active jobseeking as a necessary condition for being unemployed.
The search methods considered active are to be found listed in the European Commission Regulation 1897/2000. - Personas con discapacidad oficialmente reconocida
Aquellas personas a quienes se les haya reconocido un grado de discapacidad igual o superior al 33 por ciento. Se considerará que presentan una discapacidad en grado igual o superior al 33 por ciento los pensionistas de la Seguridad Social que tengan reconocida una pensión de incapacidad permanente en el grado de total, absoluta o gran invalidez, y a los pensionistas de clases pasivas que tengan reconocida una pensión de jubilación o de retiro por incapacidad permanente para el servicio o inutilidad.
- Active population or active persons
The active population comprises employed and unemployed persons during the reference week.
- Inactive population or inactive persons
The economically inactive population comprises all persons 16 years old and older who do not classify as employed, unemployed or population counted separately during the reference week.
- Activity rate
The activity rate is defined as the quotient between the total number of active persons and the population aged 16 years old and over.
- Employment rate
This is the quotient between the total number of employed persons and the population aged 16 years and over.
- Unemployment rate
The unemployment rate is the quotient between the number of unemployed persons and the number of active persons. Calculated for both sexes and for each sex separately.
- 3.5Statistical unit
People, from 16 to 64 years old, with disabilities and the households of which they are members.
- 3.6Statistical population
The population scope of the study is the group of persons from 16 to 64 years old with disability (degree of disability of 33% or greater and similar) who reside in main family dwellings.
Therefore, collective households are not included, although people who live in a collective household with a link to a private household, are considered part of the statistical population.
- 3.7Reference area
The entire national territory is investigated, disaggregated at the Autonomous Community level.
The fact that disability is an atypical phenomenon means that the size of the available sub-sample of persons with disabilities is insufficient to provide independent data for the Autonomous Cities. For this reason, the information relating to Ceuta and Melilla is included together with the Autonomous Community of AndalucÃa.
- 3.8Time coverage
The statistics are carried out on an annual basis.
Each year (a) data are published with reference to the previous year (a-1).
It is carried out from the year 2010 and has reference data from the year 2008.
- 3.9Base period
In 2008 the statistics began as a pilot project. Given the quality and viability of the results obtained, from this moment on it was established as a continuous statistic with an annual periodicity.

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).
There is a collaboration agreement between the INE, the Ministry of Health, Social Policy and Equality, the Spanish Committee of Representatives of People with Disabilities (CERMI), the ONCE Foundation, and the Institute for the Elderly and Social Services (IMSERSO) to carry out the study called Employment of People with Disabilities.
The agreement is renewed annually and there is a Joint Agreement Monitoring Committee made up of one representative from each of the collaborating institutions.
- 6.2Data sharing
The exchanges of information needed to elaborate statistics between the INE and the rest of the State statistical offices (Ministerial Departments, independent bodies and administrative bodies depending on the State General Administration), or between these offices and the Autonomic statistical offices, are regulated in the LFEP (Law of the Public Statistic Function). This law also regulates the mechanisms of statistical coordination, and concludes cooperation agreements between the different offices when necessary.
The information relating to disability is obtained from administrative records from IMSERSO and is completed with records from the General Treasury of Social Security (GTSS), the National Social Security Institute and the System for Autonomy and Care for Dependent Persons.
- 6.1Legal acts and other agreements
- 7Confidentiality
- 7.1Confidentiality - policy
The Statistical Law No. 12/1989 specifies that the INE cannot publish, or make otherwise available, individual data or statistics that would enable the identification of data for any individual person or entity. Regulation (EC) No 223/2009 on European statistics stipulates the need to establish common principles and guidelines ensuring the confidentiality of data used for the production of European statistics and the access to those confidential data with due account for technical developments and the requirements of users in a democratic society
- 7.2Confidentiality - data treatment
INE provides information on the protection of confidentiality at all stages of the statistical process: INE questionnaires for the operations in the national statistical plan include a legal clause protecting data under statistical confidentiality. Notices prior to data collection announcing a statistical operation notify respondents that data are subject to statistical confidentiality at all stages. For data processing, INE employees have available the INE data protection handbook, which specifies the steps that should be taken at each stage of processing to ensure reporting units' individual data are protected. The microdata files provided to users are anonymised.
The procedures for archiving and transmission of files follow the INE standards and their use is restricted to personnel in the area.
Direct identification data are not stored together with the statistical information itself.
Aggregate data meets confidentiality restrictions.
Microdata files provided to users are anonymised.

The diffusion of the information is carried out by means of a press release in which the main data are discussed.
The reference to this press release can be found at: - 10.3On-line database
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 tables can be accessed in INEbase in the section Society/Labour Market, through the following link:
- 10.4Micro-data access
A lot of statistical operations disseminate public domain anonymized files, available free of charge for downloading in the INE website Microdata Section
Due to the nature of the operation and the discrete sample size, it is not foreseen to provide microdata, since its diffusion would compromise the statistical secret.
- 10.5Other
It is possible to request customised information from the INE User Service Area. Limitations on confidentiality or accuracy are taken into account when processing such requests.

- 10.7Quality documentation
Sections 10.7 through 17 of this document collect user-oriented quality information for this operation.
- 10.1News release
- 11Quality management
- 11.1Quality assurance
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 quality of the information from the EAPS is backed up by the quality procedures applied to this statistic.
- The quality of the information coming from administrative registers is backed up by the management of the registries themselves.
- The quality of the EPD is guaranteed through the quality of the crosses carried out and through the consistency between the crossed data sources. For this, it is essential to use data from the Municipal Register (PADRON).
In section 18.1 of this report, reference is made to the quality control procedure applied to the information crossings carried out to obtain this statistic.
- 11.2Quality assessment
The main source of this statistical operation is the Economically Active Population Survey (EAPS). This statistic is a high quality product. Its sample size allows to offer indicators up to the regional level.
The use of administrative sources to obtain the data decreases the cost of the statistical operation without affecting their accuracy. In addition, to ensure such accuracy, the data go through validation and consistency checks between the variables used, which ensures that the accuracy and reliability of the final data is very high.
- 11.1Quality assurance
- 12Relevance
- 12.1User needs
The group of people with disabilities has been an axis of priority action in the social policies developed in recent years to achieve the labour integration of these people.
In Spain, since the approval of the Law for the Social Integration of the Disabled (LISMI) in 1982, the idea has been consolidated that achieving full integration into society entails achieving integration into the labour market.
The so-called "Global Action Strategy for the Employment of Persons with Disabilities 2008-2012" diagnoses low labour participation as the greatest problem of this group. In addition, it specifies a series of guidelines that, explicitly, aim to tackle the identified causes of low work activity.
In order to analyse the effectiveness of the action plans adopted, data are needed to provide information on this matter, but these are discontinuous and heterogeneous. For a long time, the group of persons with disabilities has been characterised by the lack of continuous and comparable information, both to measure the results and impacts in terms of use of the different intervention instruments, and to evaluate the challenges posed by the economic crisis in this field.In this context, the statistic "Employment of Persons with Disabilities" (EPD), developed by the INE since 2010, stands as the first continuous source of relevant information on the situation of persons with disabilities within the labour market.
The main users of the EPD statistics are:
- IMSERSO
- D.G. for Disability Support Policies
- Spanish Committee of Representatives of Persons with Disabilities (CERMI)
- ONCE Foundation
All of them need to have data on the labour force (employed, unemployed) and the population outside the labour market (inactive) within the group of persons with disabilities in order to carry out appropriate social measures. - 12.2User satisfaction
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 the users mentioned have been raised in the Agreement Monitoring Committee and have been met to date to the extent that the sample sizes have allowed.
The needs for information and coverage are raised at periodic meetings of this Committee and are stipulated in the annual agreements.
After the first edition of "The Employment of Persons with Disabilities" in which the requirements initially proposed by the Monitoring Committee had been achieved, the Committee expanded them by suggesting new information crossings that have been successfully carried out.
In 2013, the Spanish Committee of Representatives of People with Disabilities (CERMI) awarded the INE's labour statistics operations.
The jury of the CERMI awards, in its 12th edition, decided to award the prize in the category of Social and Scientific Research to the INE's annual operations on employment and salaries of people with disabilities, for its promotion of the cross-sectoral approach of disabilities in the official statistics, following the mandates of the Convention on the Rights of Persons with Disabilities.CERMI awards link:
http://www.cermi.es/es-ES/Cermi.es/Premios/Paginas/Inicio.aspx - 12.3Completeness
The EPD statistics have so far covered all the needs raised at the national level.
But given that disability is an atypical phenomenon and that the information base is supported by the EAPS, which was designed for purposes other than disability, the sample size obtained is limited and makes it impossible to perform a detailed exploitation at the regional level.
The data available for Autonomous Communities are limited to the variables prevalence, and economically active and inactive persons.
The rate of available mandatory statistical results for the EPD is R1=100%.
- 12.1User needs
- 13Accuracy and reliability
- 13.1Overall accuracy
The errors presented in the statistical process carried out for the Employment of Persons with Disabilities (EPD) differ from those usually raised in the general case of surveys.
Given that the EPD is carried out by crossing the data from the Economically Active Population Survey (EAPS) with the State Database of Persons with Disabilities (BEPD), its accuracy depends:
- The accuracy of the EAPS
- Coverage and identification errors of the BEPD - 13.2Sampling error
The Jackknife indirect method is used to calculate the sampling errors of the main characteristics investigated. The Jackknife technique was adjusted to save the added complexity of the calibration used for the EPD (calibrate the population variables used in the EAPS, to the BEPD and to the results published by the EAPS).
For the last year published, the variation coefficient of employed persons with disabilities was A1(employed persons) = 1.98%.

- 13.3Non-sampling error
Non-sampling errors inherent to the EPD statistics (excluding those produced by the conduct of the Economically Active Population Survey, essential information base for the creation of the EPD) are the following:
- Lack of identifiers in the EAPS
- Lack of identifiers in the BEPD
- The presence of duplicates in the BEPD
- The presence of deceased persons in the BEPDTo control coverage errors in the BEPD:
- The BEPD is crossed with the Death Register (of the VS) to eliminate deceased persons
- Duplicates are checked in the BEPD (people assessed throughout their lives in different provinces appear registered several times)
- The BEPD is crossed with a directory of centres to eliminate people living in collective housing.To control identification errors of the BEPD:
- The identifiers of the BEPD are normalised
- BEPD data is crossed with the Municipal Register (PADRON)
- EAPS identifiers are reviewed in order to optimise their crossing with the BEPD
- A triple process of linking the BEPD with the EAPS is carried out through several identification variables
- Persons with disabilities detected through the crossing of the EAPS with the GTSS are incorporated into the EPD statistics for having a degree of disability (variable registered in the GTSS) greater than or equal to 33%.Due to the nature of this statistic based on the crossing of records, the main reference measure for assessing non-sampling errors can be evaluated through an equivalent of non-response, which in this case would be lack of identification.The lack of identification can be estimated through the following expression:Lack of identification = Records without identifier / Records involved in the crossingThus, for the last year published, the "Lack of identification rate", thus established, stood at A4 = 0.0%.It should be noted that the presence of duplicates and deaths of the BEPD are investigated in great detail, and to the extent that the identification of persons in the BEPD allows, it can be said that they are practically completely detected and controlled. That is, for correctly identified records in the BEPD, errors due to the incorrect inclusion of duplicates or deaths is minimal.
- 13.1Overall accuracy
- 14Timeliness and punctuality
- 14.1Timeliness
The statistics data will be published at the end of the year following the reference year of the information, i.e. within TP2 = 12 months
- 14.2Punctuality
The publication has been released on the date announced in the publication calendar. The deadline for the dissemination of results is set in the collaboration agreement.
- 14.1Timeliness
- 15Coherence and Comparability
- 15.1Comparability - geographical
It should be borne in mind that the concept of disability used is restricted to legal terminology, so the possibility of comparisons of this statistic with any other survey on disability should be made under this premise.
At European level there is no comparison since it is a pioneering project that integrates labour market data and disability.
There are comparable disability data at European level in the EAPS modules, but the definitions used in these modules are not equivalent to those of the EPD.
The information provided is restricted on a regional level, since the presence of disability in the population is an atypical phenomenon. Therefore, the sample size of the EAPS sub-sample of persons with disabilities of working age obtained for the Autonomous Communities (AACC) limits the exploitation of results therein. - 15.2Comparability - over time
Royal Legislative Decree 1/2013, of 29 November, published on 3 December 2013, approving the Revised Text of the "General Law on Rights of Persons with Disabilities and their Social Inclusion" establishes that Social Security pensioners who have a recognised permanent disability pension in the degree of total, absolute or great disability, and civil service pensioners who have a recognised retirement pension or retirement pension due to permanent disability for service or uselessness shall be considered to have a disability equal to or greater than 33%.
As a consequence of this Royal Decree, since 2015 the population scope of The Employment of Persons with Disabilities includes this group. This change implies a rupture in the series of data of The Employment of Persons with Disabilities, and therefore the data already published for 2014 have been recalculated, including this new group, in order to provide a measure of the change. Therefore the number of comparable elements is CC2 = 8 years.
- 15.3Coherence - cross domain
Although the definition of disability analysed is different, the results provided by the EPD are consistent with the results on activity derived from the Survey on Disability, Personal Autonomy and Dependency Situations 2008 (EDAD-2008). Likewise, the regional distribution of persons with a disability certificate is coherent between both sources.
In order to guarantee the consistency of the data provided, the file resulting from the crossing of the EAPS with the BEPD is calibrated through the CALMAR procedure.
In order to calibrate the original EAPS elevation factors, the calibration techniques are applied in the same way as is usual in the quarterly EAPS, in such a way as to guarantee consistency with the INE population figures.
In addition, in order to ensure the consistency of the data with the EAPS information published for the data reference year, the results published by the EAPS for the data reference period are calibrated, specifically, the number of employed, unemployed and inactive men and women between the ages of 16 and 64 is matched.
In order to ensure the consistency of the data with the population with disability registered in the BEPD, the totals of the BEPD are calibrated by sex, age groups, impairment groups and degree of disability.
And, to ensure the consistency of the data with the group of Social Security pensioners with permanent disability pension in the degree of total, absolute or great disability, and civil service pensioners who have a recognised retirement pension or retirement pension due to permanent disability for service or uselessness, the totals of this group are calibrated differentiating by sex.
- 15.4Coherence - internal
Consistency is a fundamental question both in the EAPS methodology approach and in all its preparation process.
The consistency between the variables coming from the different administrative registers is contrasted in all the phases of the statistical process. Specifically, it should be pointed out that:
- In order to ensure consistency between the EAPS population and the BEPD, persons residing in collective establishments are removed from the BEPD.
- In order to ensure consistency between the variables on sheltered employment from the GTSS, a detailed analysis is carried out of the employment status described in the EAPS for each person, in the reference week, as opposed to the different employment status that appear in the Social Security registration records.
- 15.1Comparability - geographical
- 16Cost and burden
- 16.1Cost and burden
The estimated budget appropriation necessary to finance this operation foreseen in the 2023 annual programme is 87.63 thousand euros.
The burden on the respondents is nil as the information comes from administrative sources.
"The Employment of People with Disabilities" is a model that uses low-cost administrative sources that employs efficient methods and provides periodical figures on an aspect that is the subject of social and labour policies.
- 16.1Cost and burden
- 17Data revision
- 17.1Data revision - policy
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-.
The information published is final and therefore no revision of data is carried out.
- 17.2Data revision - practice
The information published is final and therefore no revision of data is carried out.
- 17.1Data revision - policy
- 18Statistical processing
- 18.1Source data
This statistical operation uses the information derived from an integration of the statistical data provided by the Economically Active Population Survey (EAPS) with the administrative data registered in the State Database of Persons with Disabilities (BEPD) of IMSERSO.
It is completed with information on pensions, dependency and employment promotion measures from the Public Benefits Register of the INSS, the System for Autonomy and Care for Dependent Persons (SISAAD) of IMSERSO and the General Treasury of Social Security (GTSS), respectively.
First, the data from the EAPS (Economically Active Population Survey) are crossed with that of the BEPD (State Database of Persons with Disabilities).Then, information from three other data sources is incorporated:
- Registry File of Public Social Benefits provided by the National Institute of Social Security (INSS) .
- Social Security Registrations file sent by the General Treasury of Social Security (GTSS).
- Information collected in the Information System of the System for Autonomy and Care for Dependent Persons (SISAAD), for which IMSERSO is administratively responsible.
In order to guarantee the quality of the results, the following actions are carried out:
- Quality of the cross-checks
- Exhaustive cleaning of the identification of the persons included in the BEPD using the municipal register data as reference.
- Detailed revision of the identifiers assigned to the EAPS with data from the municipal register
Completion of the disability population of the BEPD with poor identification through the incorporation of persons from the EAPS sample crossed with GTSS who have a degree of disability greater than or equal to 33%.
- Consistency of sources
- Crossing of BEPD with VS to remove deceased persons
- Duplicate control in the BEPD (people assessed throughout their lives in different provinces are recorded several times)
- Crossing the BEPD with a directory of centres to eliminate people residing in collective housing.
- The directory of centres used is the one originally used for the EDAD survey, but updated with the following information:
– Database of Centres for the Elderly dependent on the High Council for Scientific Research and IMSERSO– List of IMSERSO reference centres (IMSERSO website, few centres)– Directory of Centres for Persons with Disabilities < 65 years registered in the Catalogue of Services for Persons with Disabilities (Directorate General of Disability Support Policies)–CBR: restricted to establishments with CNAE activity 8720= Assistance in residential establishments for persons with intellectual disability, mental illness and drug addiction; and CNAE 8732= Assistance in residential establishments for persons with physical disability- Calibration of elevation factors within each Autonomous Community to adjust the results to the BEPD totals by age groups, sex, impairment groups and degrees of disability
- Calibration of elevation factors within each Autonomous Community to adjust EPD results to the main disseminated EAPS results: employed, unemployed and inactive persons aged 16 to 64 years
- Calibration of elevation factors within each Autonomous Community to adjust the results to the totals of pensioners who have a recognised permanent disability pension by sex.
- 18.2Frequency of data collection
In this project there is no specific collection as such. It is not a survey, although it is based on EAPS data, which is collected quarterly.
The information from the BEPD is provided annually by IMSERSO.
Data on sheltered employment, benefits and dependency are provided by the General Treasury of Social Security, the National Institute of Social Security and IMSERSO, respectively, once a year.
- 18.3Data collection
This is a statistical operation that crosses data from the Economically Active Population Survey (EAPS) with administrative records, so there is no collection work.
- 18.4Data validation
- In order to cross-check the two data sources, firstly, identifiers (national identity card or foreigner identification number) have been assigned to each of the persons aged 16 years old and over interviewed in the EAPS, for which the survey records have been compared with the Municipal Register of Inhabitants.
The EAPS has the following personal data, which are collected in the interview: name, surname, sex, place and date of birth and place of residence of the family dwelling. Through them, the identification number that appears in the Municipal Register is assigned, using direct or probabilistic assignment techniques.
- At the same time, the State Database of Persons with Disabilities is cleaned, in order to ensure the correct identification of all its registers and to eliminate those corresponding to deceased persons and those of residents in collective dwellings. For this purpose, we have used as contrast files the Municipal Register, the Death Statistics files and a directory of centres (constructed on the basis of the directory of centres used in the EDAD-2008 survey and updated annually with data from the CBR, centres for the Elderly, residential centres and IMSERSO reference centres).
- In order to cross the EPA data with the GTSS, INSS and SISAAD data, the INE sends the EAPS identifiers file to these bodies, and they are the ones who cross the data through the numerical code of the Physical Person Identifier (IPF).
- Then, each quarter of the EAPS is crossed with the BEPD, adding the information from the administrative source to the information from the survey.
- The validity of all these cross-checks is controlled in the INE through the conjunction of the following measures:
- Measure of similarity of name and surname (routine comparison of alphanumeric strings defined and implemented in the Area of Employment of Persons with Disabilities of the INE)
- Date of Birth Comparison Measure
- IPF similarity measureThe union of all of them provides admission/rejection criteria for the cross-checks carried out.
- 18.5Data compilation
The data compilation process is carried out in the following phases:
1. The cross-checks are validated with each of the data files received with the quarterly EAPS files, in such a way that for each person in the EAPS there are the variables of the EAPS questionnaire plus the variables of disability, employment promotion measures and social protection coming from the administrative registers used.
3. The elevation factors are calibrated
4. With the 4 quarterly files with elevated data, the annual average is calculated for each variable considered.
5. The tables to be published are obtained with the annual results (calculated as annual average from the elevated quarterly results).
- 18.6Adjustment
1. For the EPD, the factors deduced from the EAPS design are used, calibrated reproducing the exact procedure carried out in the Economically Active Population Survey:
The factors are calibrated, for each Autonomous Community, in such a way that the population is adjusted to:
- the five-yearly sex and age groups by Autonomous Community
- the population of 0-15 and 16 and more by provinces
- the total number of Spaniards/foreigners by Autonomous Community
2. Furthermore, additional calibration marginals are added to adjust the population to the BEPD totals and to the results published by the EAPS for the reference year:
ADDITIONAL MARGINALS EAPS RESULTS (for Autonomous Communities, population 16-64 years old):
Employed persons by sex
Unemployed persons by sex
Inactive persons by sexADDITIONAL MARGINALS BEPD (for Autonomous Communities, population aged 16-64)
Sex
Age groups (16-24, 25-44, 45-64)
Number of persons according to type of disability (9 groups)
Number of persons according to degree of disability (33%-44%, 45%-64%, 65%-74%, 75% and more)3. Additional calibration marginals are added to adjust the population to the totals of pensioners who have a recognised permanent disability pension:
ADDITIONAL MARGINALS PERMANENT DISABILITY (for Autonomous Communities):
Sex
It should be noted that the EAPS variables that have not been calibrated do not coincide in their results with those obtained in the operation âEmployment of persons with disabilitiesâ, although they are consistent.
The entire factor adjustment process is carried out using the CALMAR calibration procedure
