- 10.7Quality documentation
  
  Fields 10.6 to 17 of this document are the user-oriented quality report for this operation.
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 Basic Demographic Indicators are calculated from individual data collected in the Vital Statistics, in the Migration Statistics, in the Statistics of Migrations and Changes of Residence, in the Annulments, Separations and Divorces Statistics based on the reference resident population figures (Intercensal Population Estimates, until 2020, and annual Censuses, since 2021) and the Continuous Register Statistics for the municipal indicators corresponding to the period 2014-2020 and the annual Censuses since 2021. The quality of these is guaranteed by the quality of the original sources.
  
  In addition, for these indicators, analysis of variable completeness is carried out, outliers check of the information sources on which they are based and they are subjected to an exhaustive analysis of their temporal series of results, in order to avoid any error in their calculation. An international data comparison is also carried out.
  
  This statistical operation is subject to an exhaustive analysis of variable completeness, atypical values and the temporal series of results, in order to avoid any error in the calculation of indicators or in the sources of information from which they are calculated.
- 11.2Quality assessment
  This statistical operation provides a total consistency of results between all territorial levels considered and the necessary coherence between demographic flows and population stocks.
  
  The complete consistency of the indicators is also guaranteed with:
  - the numbers of births, deaths, and marriages provided by the Vital Statistics
  - the migration figures provided by Migration Statistics until 2020 and the Migration and Changes of Residence Statistics from 2021.
  - the divorce figures provided by the Annulments, Separations and Divorces Statistics
  - the figures of population obtained from intercensal population estimates for the period 1971-2020 and from the annual Censuses since 2021.
  - the figures of population at municipal level obtained from the Statistics of the Continuous Register for the period 2014-2020 and the annual Censuses starting in 2021.
  The weak point of this statistical operation is that the indicators corresponding to small populations are more unstable and are more subject to circumstance. For this reason, three-year municipal inficators are calculated, which will be mobile to generate a time series.
12Relevance
- 12.1User needs
  
  This operation provides a summary of the demographic evolution of Spain, of each Autonomous Community and of each province since 1975, carried out in terms of the indicators usually used in demography. It is available to all users who need to analyse the demographic evolution of the country.
  
  These indicators are used internationally to make demographic comparisons of the behaviour of the demographic phenomena in different countries (gross birth rate, mortality rate, mean age at maternity, life expectancy...).
  
  Regular users include the United Nations and the most demanded indicators are Life Expectancy, Average Number of Children per Woman and Average Age at Maternity.
  
  Since 2019, results have been available at the municipal level. The availability of the municipal detail of the information on demographic events in the Statistics of the Natural Movement of the Population allows the calculation of indicators referring to the population registered in each municipality, making use of the figures of the Municipal Register on January 1 of each year for the period 2014-2020 and the annual Censuses starting in 2021.
- 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)
- 12.3Completeness
  
  The statistical operation of Basic Demographic Indicators is included in the National Statistical Plan 2021-2024 with code 8883 and its code in the Inventory of Statistical Operations (this code is a fixed identifier of the statistic, which does not change) is 30264.
  
  This operation complies with 100% (R1=100) with the objectives set by the National Statistical Plan 2021-2024 providing information on the main characteristics of the current demographic situation in the whole national territory, its Autonomous Communities and its provinces through the elaboration of summaries and analysis with results from various sources.
13Accuracy and reliability
- 13.1Overall accuracy
  
  This operation is based on the information provided by the Vital Statistics, the Migration Statistics, the Statistics of Migrations and Changes of Residence, in the Statistics on Annulments, Separations and Divorces and the resident population figures (Intercensal Population Estimates, until 2020, and annual censuses, from 2021) and of the Statistics of the Continuous Register for the municipal indicators corresponding to the period 2014-2020 and the annual Censuses from 2021, therefore the accuracy of the results depends on the information sources used. Finally, the coherence between related indicators is also analyzed.
- 13.2Sampling error
  
  Not applicable to this statistical operation, as it is a summary statistic, elaborated from other statistical sources, and not from a sample survey.
- 13.3Non-sampling error
  Since this is a summary operation, based on the statistical treatment of data from registry sources, non-sampling errors in this statistical operation are mainly due to:
  - Possible data recording errors in the Birth bulletin, Death bulletin and Marriage bulletin collected in the Civil Registers of the whole national territory, from which the Statistics on Births, Deaths and Marriages of the Vital Statistics are elaborated.
  - Any possible errors in recording the data in the statistical bulletins that are completed by the various courts using a web form in accordance with the Agreement signed by the INE with the General Council of the Judiciary (GCJ) where they collect information on the rulings on annulment, separations or divorces dictated by the corresponding judicial body, from which the Statistics on Annulments, Separations and Divorces are elaborated.
  - Possible errors in the registration of data in the Register, necessary to prepare both the Migration Statistics and the Statistics of Migrations and Changes of Residence as well as the reference resident population figures (Intercensal Population Estimates, until 2020, and annual Censuses, since 2021) as well as the continuous Register Statistics itself for the period 2014-2020.
  - Any possible errors regarding completion and coherence of the variables used in the calculation of the indicators are monitored during the control and filtering processes of the aforementioned operations.
  However, the indicators are subject to an exhaustive analysis within the time series of each one of the indicators, in order to avoid any error in their calculation.
14Timeliness and punctuality
- 14.1Timeliness
  
  Final results are published 11 months after the end of the reference year (TP2=11 months).
  
  In the case of mortality results at the municipal level, they are published 23 months after the end of the reference year.
- 14.2Punctuality
  
  The publication of the Basic Demographic Indicators is carried out according to the deadline established in the structural statistics calendar that the INE elaborates and publishes for each year.
15Coherence and Comparability
- 15.1Comparability - geographical
  
  The basic demographic indicators have complete inter-regional consistency at all levels of disaggregation, since this is the case with the data sources on which they are based, Vital Statistics, Migration Statistics, the Statistics of Migrations and Changes of Residence, Statistics on Annulments, Separations and Divorces and resident population figures (Intercensal Population Estimates, until 2020, and annual censuses, from 2021) and of the Statistics of the Continuous Register for the period 2014-2020 for the municipal indicators.
  
  Furthermore, the indicators are calculated with a homogeneous methodology for any territorial disaggregation, so that their Autonomous and Provincial results are fully comparable.
  
  On an international scale, they are also comparable, since there are European regulations for the main concepts on which they are based (resident population, vital statistics and migration statistics), although there is no specific regulation of basic demographic indicators.
  
  In other words, all the basic demographic indicators refer to the concept of "resident population" according to the definition of habitual residence established in Regulation 1260/2013 of the European Parliament and Council on European demographic statistics.
  
  The basic demographic indicators, based on vital statistics, comply with Commission Regulation (EU) No 328/2011 of 5 April 2011 implementing Regulation (EC) No 1338/2008 of the European Parliament and Council on European Union statistics on public health and health and safety at work, as regards statistics on the causes of death. Furthermore, they are comparable with the rest of the European Union countries as they follow the Eurostat recommendations established for all the countries and agreed in the meetings of the Demographic Statistics working group.
  
  As for the migratory movement indicators, the flows on which they are based conform to the definitions established in Regulation 862/2007 of the European Parliament and Council on Migration Statistics and International Protection and sponsored, in turn, by the United Nations, which favours their international comparability.
  
  However, there may be differences in the calculation methodologies for some demographic indicators between the different countries (average ages, average population, among others).
- 15.2Comparability - over time
  
  The results are comparable over time.
  
  In general, most basic demographic indicators go back to 1975 without breaks in the series (the first year for which this statistic is produced). Therefore, in general, the number of comparable elements in the time series for most demographic indicators from their inception in 1975 until the last publication of definitive data in 2023 covers 49 annual periods (CC2=49).
  
  The indicators on migratory movement go back to 2008, the first year for which Migration Statistics was compiled. Therefore, the number of comparable elements of the time series relating to these indicators from their inception in 2008 until the last publication of definitive data in 2023 covers 16 annual periods (CC2=16).
  
  Divorce indicators go back to 2005. Therefore, the number of comparable elements of the time series relating to these indicators from their inception until the last publication of definitive data in 2023 covers 19 annual periods (CC2=19).
  
  Indicators at the municipal level are rolled back to 2014. Therefore, the number of comparable elements of the time series relative to these indicators from their beginning to the last publication of definitive data for 2023 covers 10 annual periods (CC2 = 10) for all demographic phenomena except for mortality and population structure indicators. The number of comparable elements of the time series relating to mortality indicators at the municipal level from their inception to the last publication of definitive data in 2022 cover 9 annual periods (CC2=9) and the number of comparable elements of the time series relating to Population structure indicators at the municipal level from their inception to the last publication of definitive data in 2024 cover 11 annual periods (CC2=11).
- 15.3Coherence - cross domain
  
  This operation is based on the results of the Vital Statistics, Migration Statistics, of Migration and Changes of Residence Statistics, Statistics on Annulments, Separations and Divorces and resident population figures (Intercensal Population Estimates, until 2020 Intercensal Population Estimates, until 2020, and annual Censuses, from 2021) and of the Statistics of the Continuous Register for the period 2014-2020, therefore its results are fully consistent with those of these sources.
- 15.4Coherence - internal
  
  The data is fully consistent across territories and demographics.
16Cost and burden
- 16.1Cost and burden
  
  The basic demographic indicators are a statistical summary operation that uses data from other operations. Therefore, it does not burden the user and makes it possible to obtain, at a low cost, a significant volume of demographic information.
  
  The budgetary estimate necessary to finance this operation, provided for in the 2024 Annual Programme, is 126.06 thousand euros.
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-.
  
  In the case of Basic Demographic Indicators, the definitive data are prepared from the definitive results of these sources on which they are based, 11 months after the end of the reference period.
- 17.2Data revision - practice
  
  In May 2016, an extraordinary revision of all the series of Basic Demographic Indicators took place, in order to incorporate the Intercensal estimates of the Population for the 1971-2001 period that were recalculated between the years 2014 and 2015. The objective was to produce a continuous series of population figures that began on 1 January 1971 and is linked to the last published period of the Population Figures statistics since the series of Intercensal Population estimates published up to 2015 had been elaborated according to different smoothing processes by age, in such a way that they did not constitute a homogeneous series.
  
  In September 2017, an extraordinary revision of all the series of Population Structure Indicators corresponding to 2016 took place, due to the corrections for people aged 100 and over in the Population Figures operation on 01/01/2016, which constitutes the fundamental source of information for the calculation of these indicators.
  
  This correction, from the population volume of individuals aged 100 and over in the Population Figures operation on 01/01/2016, also affects the specific mortality rates for this age group (closing age of the mortality tables) in 2015, as well as the population growth results per thousand inhabitants in 2015, therefore they were also updated.
  
  On this same date, the series of life expectancies from 1991 to 2015 was updated in line with the modification made to the Mortality Tables.
  
  In June 2018, there was an extraordinary revision of all the series of Indicators corresponding to the demographic phenomena of birth and fertility, mortality, marriage and divorce, as well as the migratory and population growth indicators of 2016 and the indicators of population structure of 2017, as a consequence of the correction for people aged 100 and over in the population figures operation on 01/07/2016 and 01/01/2017.
  
  In June 2019, the Fertility Indicators were recalculated according to the order of birth of the period 1996-2006 to take into account the modification of the calculation method of this variable in the Birth Statistics of the Vital Statistics of that period. Thus, for the years before 1996, all live births in a multiple birth had the same order (number of children born alive in previous births + number of children born alive in the current birth). As of 1996, the method for calculating the order of birth variable is modified so that each child born alive in a multiple birth has the correlative order that corresponds to it.
  
  On this same date, the level of disaggregation of the age variable for the Migratory Indicators at the autonomous and provincial levels is modified so that it is equal to the level of detail published in the Migration Statistics. As a result, all migration indicators that use age-specific rates for their elaboration have been recalculated.
  
  In June 2020, the Population Structure Indicators at the municipal level include the Proportion of people according to place of birth, consisting of five indicators or proportions of “autochthony” at different territorial levels in which the place of birth is compared with place of residence.
  
  In October 2020, Mortality Rates by sex, age and educational level for all territorial levels and Life Expectations by sex, age and educational level are included in the Mortality Indicators. In both cases, 4 educational levels are considered by aggregation of the Classification of programs, degrees and certifications in levels of training achieved, CNED-A.
  
  In December 2021, the 2016 mortality rate was corrected for the closing age of the Mortality Tables published by the INE.
  
  On the occasion of the new 2021 Population Census, published in December 2022, throughout the year 2023, the intercensal population series were calculated for the period 2012-2020, in order to obtain a continuous and unified series of population figures that it begins on January 1, 1970 and links to the first published period of the annual Population Censuses as of January 1, 2021 and subsequent ones.
  
  In November 2023, the Basic Demographic Indicators for the period 2012-2020 are published, calculated on the population base of the new intercensals and annual censuses.
  
  In November 2024, the basic demographic indicators from 2021 onwards for all phenomena except mortality will no longer be triennial and will be calculated taking into account only the year of study, exactly the same as what is done for the annual indicators. provincial, autonomous community and national level. Another novelty, in this case, is that starting in 2021 the list of municipalities for which basic demographic indicators of all demographic phenomena are offered is a fixed list of 155 municipalities.
