The Taxi Statistics is a census that INE has been carrying out since 1994 in collaboration with city councils and which aims to provide information on the amount of taxis available each year in each Autonomous Community, province and provincial capital, also distinguishing between those that have taximeters and those that do not.
Please note that with reference to 1996, INE carried out a survey aimed at taxis and other public service passenger cars, as well as requesting economic and legal information, which from 1999 was included in the Annual Services Survey.
The statistic focuses on the sector of car rental with a driver, and more specifically those vehicles with an associated auto-taxi or auto-tourism license.
The statistical unit of the survey is the taxi.
The population under study is made up of all operating taxis with a valid licence for the reference year.
All taxis located in the national territory are the subject of this research.
The historical series begins in 1994.
The reference period is the calendar year.
Data referring to the period: Annual Y: 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 2017-2020, approved by Royal Decree 410/2016, of 31 October, is the Plan currently implemented. This statistical operation has governmental purposes, and it is included in the National Statistics Plan 2017-2020. (Statistics of the State Administration).
There is no EU Regulation for this statistical operation.
The provincial INE sections collect the information provided by the City Councils every year.
All statistical personnel are obliged to preserve statistical confidentiality (art. 17.1 of the Law on the Public Statistics Function - LFEP). In the specific case of this statistical census, only aggregated information at the provincial level is published.
The frequency of data publication is annual.
There are no specific publications. The statistical results are published annually on the INE website and in some publications such as Anuario Estadistico del INE (INE Statistical Yearbook) .
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.
Survey results are available from 1994 to present.
Tables and historical series can be accessed from the INEbase within the section Services/Transport at www.ine.es
Information can be consulted regarding the amount of taxis available per year in each Autonomous Community, province and provincial capitals.
In 2017, AC1 = 4131 annual accesses to the INE web page were recorded to consult tables containing information related to the Taxi Statistics operation, and the number of accesses to the metadata was AC2 = 545.
In this statistical operation, no microdata is released.
The description of the statistical data can be found at https://www.ine.es/metodologia/t10/t10p109.pdf
The rate of completeness of the metadata is AC3=100%.
The Taxi Statistic is a survey based on the available administrative information. This report presents quality indicators on the management undertaken for this statistical operation. Sections 10.6 to 17 of this document are the user-oriented quality report for 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 process for the production of taxi statistics is designed to guarantee the quality of the information used, as well as that of the results obtained from it. To this end, different quality controls have been developed at each stage of the process, such as the detection of invalid values and other permanent controls on the flow of information.
The Taxi Statistics are carried out in accordance with EU guidelines, complying with the Code of Practice implemented by Eurostat and taking the necessary measures to ensure that the published data complies with the necessary quality requirements.
The Taxi Statistic is a census whose source are the city councils themselves, which ensures reliable information and high quality statistics, reducing the burden on the respondent, which allows information up to the municipal level to be provided, offering an extremely valuable measure of the amount of operating taxis, which no other statistical source provides with the same level of detail.
The Taxi Statistic covers the information needs of different user groups:
Each of these users has different needs according to the destination and utility of the information they need.
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)
Although there are no regulations that stipulate the information to be provided, the survey satisfies most of the users' needs and provides all the information requested. As far as unsatisfied needs are concerned, they are solved by means of tailored requests, whenever possible and safeguarding confidentiality.
As far as possible, these unmet needs are incorporated into the survey, when the methodology is updated.
Therefore, the completeness rate in 2018 was R1=100%.
The different processes of the statistical data are aimed at eliminating or reducing errors as much as possible, both in the collection phase (monitoring response rate and filtering control) and in subsequent editing phases. As it is a census, this statistic does not present sampling errors.
Since it is a census, there is no sample and therefore no sampling errors.
Special attention is paid to recording, editing and non-response errors (obtaining a non-response rate per unit of A4=0% coinciding, with the way in which the operation is defined, with the non-response rate per item A5=0%). Therefore, the imputation rate in 2018 was A7=0%.
Approximately TP2=4 months elapse between the reference date of the information and the date of publication of the results.
Data is delivered promptly on the date announced in the calendar of structural publications . Therefore TP3=0.
The data is comparable between the different Autonomous Communities, provinces and provincial capitals.
Since there have been no methodological changes, all the statistical indicators are comparable from 1994 onwards, with the number of comparable elements (CC2): 25
There is no cross-over between sectors at present.
The coherence between the variables is compared in all phases of the statistical process.
The cost is not available, in any case the statistics do not represent a burden for the respondents, since the information comes from administrative records of the city councils.
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-.
Solely definitive data is published.
Only definitive data is published. If an error is detected, it is corrected and users are notified.
The source of information used in this statistical operation is based on administrative data. The information is exhaustive and is provided annually by the various city councils that supply the number of taxi licenses with and without taximeter valid as of 1 July each year.
Data collection takes place annually.
The INE sends questionnaires to the corresponding City Councils, with a current response rate of 100%.
Validation criteria are established between related variables and in the same variable by comparison over time, given that the published historical series are homogeneous and therefore comparable temporally and geographically.
Once the questionnaires have been collected from the corresponding City Councils and after the corresponding filtering and validation phases, INE processes the information, aggregating it at provincial and Autonomous Community level for publication.
No data adjustments are made.
