3.1. Data description

Data on European cities were collected in the Urban Audit and in the Large City Audit project. The projects' ultimate goal is to contribute towards the improvement of the quality of urban life: it supports the exchange of experience among European cities; it helps to identify best practices; it facilitates benchmarking at the European level and provides information on the dynamics within the cities and with their surroundings.

 

For information on the data disseminated by Eurostat please refer to the UA reference metadata.

The data collection provides information and comparable measurements on the different aspects of the quality of urban life in cities.
Availability of data see annex 1; description of the data see annex 2a/b.



Annexes:
Annex 1 - Availability
Annex 2a
Annex 2b
3.2. Classification system

Specific classification and coding systems have been developed for the spatial units and for the variables and indicators. For the description of the coding system and the list of indicators and variables see the Eurostat Methodological manual on city statistics (2017 edition).

3.3. Coverage - sector

The indicators and variables cover several aspects of quality of life, for e.g. demography, housing, health, crime, labour market, income disparity,educational qualifications, environment, climate, travel patterns and cultural infrastructure.

In 2015 another brochure was released, focusing on the added value of the data collection for national and international comparisons. It also includes a chapter on the Urban Audit Sub-city level.

Both brochures are available in English or German. Printed copies can be ordered free of charge (urbanaudit@mannheim.de).

In 2016 a brochure on the estimations from the German micro census was released, documenting the method as well as showing the added value of the data. The brochure is available in German. Printed copies can be ordered free of charge (urbanaudit@mannheim.de).

Not applicable.

10.5. Dissemination format - other

Not applicable.

10.6. Documentation on methodology

The definitons of the  Eurostat Methodological manual  on city statistics (2017 edition)  have been followed. In cases of deviating methodologies, annex 2a/b inform on the methodology applied:

  • For data from official regional statistics see methodologies under DESTATIS.de,
  • for data from the Micro-Census, estimations by the cities are based on smoothed time series of >5 years of NUTS3 data.

The quality assurance procedures detailed in the  Eurostat Methodological manual  on city statistics (2017 edition) have been applied.

10.7. Quality management - documentation

The quality assurance procedures detailed in the  Eurostat Methodological manual on city statistics (2017 edition) have been applied.


11. Quality management Top
11.1. Quality assurance

In addition to the general procedures in official statistics, arranging the collected Urban Audit data in time-series helps to ensure their plausibility and comparability.

11.2. Quality management - assessment

The data originating from official regional statistics undergo the detailed quality management procedures of the federal and state statistical offices, similarly the data from other official sources. Quality management of the NGOs, like those of the cultural institutions are not regulated and not so well documented, although they are controlled by their members. All data compiled are checked by the NUAC's office and again by the EDIT-tool provided by Eurostat. It is an important feature of the Urban Audit that all data are harmonised to comply with the prescribed definitions as published in the Eurostat Methodological Handbook on city statistics.


12. Relevance Top
12.1. Relevance - User Needs

User needs and stakeholder requirements are collected at several forums.

12.2. Relevance - User Satisfaction

User needs and stakeholder requirements are collected at several forums. Comments and contributions are welcome to be sent to the contact.

12.3. Completeness

Overview of data availability is provided in annex 1. For missing variables see annex 4: Examples are for the city: dwellings lacking basic amenities; these variables  would require primary surveys. Nationality for some cities and at distirict level (Landkreis) had to be estimated from the Micro-Census, empty dwellings and social housing are not available for some cities or are based on vague estimates and are not available for districts (Landkreise); for SCD accordingly and not available for age groups of the economically active and for the educational level.



Annexes:
Annex 4 - Missing data


13. Accuracy Top
13.1. Accuracy - overall

Data quality is generally good.

13.2. Sampling error

Not applicable.

13.3. Non-sampling error

Not applicable.


14. Timeliness and punctuality Top
14.1. Timeliness

Depends on the domain and individual variable. As a general rule, timeliness is about 24 months.

14.2. Punctuality

Data provision follows the timetable of the project, with a time lag of 1 - 2 years.


15. Coherence and comparability Top
15.1. Comparability - geographical

Due to the sometimes deviating definitions and different data sources used the comparability of data is limited to some extent. Detailed information on data sources and deviating definitions is available in the annex.

The implementation of a fully comparable definition of cities at European level has improved the comparability.

15.2. Comparability - over time

Breaks in the time series are flagged accordingly. (Flag b)

15.3. Coherence - cross domain

Data collected at sub-national level is coherent with the data collected at national level to a limited extent due to the different data sources used. Most data for cities and FUAs originate from official statistics, most SCD-data originate from municipal and other registers and are adjusted to the city and FUA data.

15.4. Coherence - internal

Internal coherence (e.g. between spatial levels, between indicators like total, male, female population) is ensured through the application of multivariable and univariable validation controls.


16. Cost and Burden Top

The data collection is based on administrative data so the main burden is on the Statistical Institutes.


17. Data revision Top
17.1. Data revision - policy

Not applicable.

17.2. Data revision - practice

Not applicable


18. Statistical processing Top
18.1. Source data

Data are collected from more than 10 different sources as described in the meta data annex 2a/b. The main sources are:

  • data collected from the cities via internet
  • regional statistics of the federal and the state statistical institutes
  • special data collection by DESTATIS from state statistical institutes
  • estimations based on the official micro-census
  • estimations based on statistics of the Federal Employment Agency (BA), micro-census and official statistics of civil servants
  • crime statistics of the Federal Criminal Police Office (BKA)
  • statistics by the federal register of motor vehicles (KBA)
  • property price statistics of the research institute of real estate agents (IVD)
  • cultural statistics by the research institutes of cultural organisations

 



Annexes:
Annex 2a
Annex 2b
18.2. Frequency of data collection

The Urban Audit is a multiannual data collection.
The reference period of the current data collection is 2015/2016
The reference year of the exhaustive data collection is 2011. The reference years of the annual data collection are 2015 and 2016.

18.3. Data collection

Data is collected by the National Urban Audit Coordinator, in the case of Germany by KOSIS-Gemeinschaft Urban Audit in cooperation with DESTATIS as coordinator. It follows the guidelines of the Eurostat Methodological Handbook on city statistics.

18.4. Data validation

KOSIS-Gemeinschaft Urban Audit, responsible for this project, relies, first of all, on data validation of official regional statistics as described by DESTATIS on their website. It makes plausibility checks by comparisons over time, aggregating subdivisions of variables and comparing indicators between territorial units. In addition the EDIT-tool with extensive validation procedures provided by Eurostat is used.

18.5. Data compilation

Data from the national Micro-Census are broken down to the level of NUTS3 and LAU2 by estimations based on time series of > 5 years and fitted to key values of official regional statistics. Labour maket and employment data are estimated on the basis of statistics of the Federal Employment Agency adjusted to MC-results for the Federal States. SCD-data are proportionately adjusted to the city values.

18.6. Adjustment

Not applicable.
