3.1. Data description | |||
Data on European cities were collected in the City Statistics, 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 city statistics 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. Annexes: Annex 1 - Availability Annex 2a - Description of the data |
|||
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. |
|||
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. |
|||

For most variables the definitons of the Eurostat Methodological manual on city statistics for existing international standards have been followed. In case of deviating definitions, information is provided in annex 2a. |
|||
3.5. Statistical unit | |||
Statistical units are mostly persons. Few variables are collected on households, enterprises, dwellings, cities, etc. For the complete description of variables see the Eurostat Methodological manual on city statistics. |
|||

For most variables the target statistical universe is the usual residents of a geographical area (City and Functional Urban Area). For the detailed description of variables see the Eurostat Methodological manual on city statistics. |
|||
3.7. Reference area | |||
Spatial Units are listed in the Eurostat Methodological manual on city statistics. |

10.6. Documentation on methodology | |||
The definitons of the Eurostat Methodological manual on city statistics have been followed. In cases of deviating methodologies, annex 2a informs on the methodology applied:
The quality assurance procedures detailed in the Eurostat Methodological manual on city statistics have been applied. |
|||
10.7. Quality management - documentation | |||
The quality assurance procedures detailed in the Eurostat Methodological manual on city statistics have been applied. |
|
|||
11.1. Quality assurance | |||
In addition to the general procedures in official statistics, arranging the collected City Statistics 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 City Statistics that all data are harmonised to comply with the prescribed definitions as published in the Eurostat Methodological Handbook on city statistics. |

|||
13.1. Accuracy - overall | |||
Data quality is generally good. |
|||
13.2. Sampling error | |||
Not applicable. |
|||
13.3. Non-sampling error | |||
Not applicable. |
|
|||
14.1. Timeliness | |||

|||
14.2. Punctuality | |||
Data provision follows the timetable of the project, with a time lag of 1 - 2 years. |
|
|||
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 2a. 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. |
|||
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. |
|
|||
The data collection is mostly based on administrative data so the main burden is on the Statistical Institutes. |
|
|||
17.1. Data revision - policy | |||

Annexes: Annex 2a - Description of the data |
|||
18.2. Frequency of data collection | |||
The Urban Audit is a multiannual data collection. |
|||
18.3. Data collection | |||
Data is collected in the case of Germany by the NSI DESTATIS (coordinator) and a commissioned sub-contractor. It follows the guidelines of the Eurostat Methodological manual on city statistics. |
|||
18.4. Data validation | |||
Data validation of official regional statistics is conducted 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 LAU by estimations based on time series of > 5 years and fitted to key values of official regional statistics. Labour market and employment data are estimated on the basis of statistics of the Federal Employment Agency adjusted to Micro-Census results for the Federal States. |
