The data collection provides information and comparable measurements on the different aspects of the quality of urban life in cities.

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 Methodological Manual of City Statistics.

The indicators and variables cover several domains including: Demography (DE), Social Aspects (SA), Economic Aspects (EC), Training and Education (TE), Environment (EN), Travel and Transport (TT) and Culture and Recreation (CR).

For most variables the definitions within the Methodological Manual on City Statistics existing international standards have been followed. However, in compiling the data some deviations have resulted and are detailed in the UK Metadata Report (See below link).

Most of the Urban Audit data relate to the “number” e.g. of persons in Demography.

A full concise list of the variable units can be found in Methodological Manual on City Statistics

For most variables the target population are the residents living within a European City Statistics city.

A detailed description of the statistical populations used see the Methodological Manual on City Statistics.

United Kingdom (UK).

2011, 2008, 2004 and 2001 are the reference years for the main data collection. 1996 and 1991 were the reference years for the 'Historical' data collection.

A subset of variables has been collected on an annual basis for the period 2005-2018.

Not applicable.

The unit of measurement varies from variable to variable.

They are listed in the manual of Methodological Manual on City Statistics.

The reference period for this metadata is 2018.

Regulation (EC) No 223/2009 on European statistics (recital 24 and Article 20(4)) of 11 March 2009 (OJ L 87, p. 164), 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. 

Additionally, all data are quality assured by the European City Statistics team in the UK in order to prevent disclosive information from being transmitted.

Where necessary disclosive data are removed from datasets during quality assurance. This may mean that some variables where there are male, female and total for instance, may not add up to the total count.

European City Statistics data analysis is published in line with the release policy.

The database is updated depending upon the availability of new and revised data.

Not applicable.

Data analysis is published on the Office for National Statistics website.

The definitions of the Methodological Manual on City Statistics have been followed for most variables. Additional information on the deviating methodology used in the collection is provided in the UK Metadata Report (see below link).

The quality assurance procedures detailed in the Methodological Manual on City Statistics have been applied. Additional information on quality is provided in the UK Metadata Report.

Sources of data are checked for compatibility with the definitions set out in the Methodological Manual on City Statistics. Small differences are flagged with a 'd' for deviating definitions and are further explained in the UK Metadata Report.

Data are taken from official data sources that are checked and validated as part of their release.

Data are checked for level of change over time and outliers are invetigated further. Data considered to be disclosive are removed. Further checks are carried out to ensure that data accuracy has been maintained throughout processing.

It is recommended that users always refer to the Metadata Report and source metadata to assess whether the data are suitable for their needs particularly when using estimates indicated by an ‘e’.

The European City Statistics project is to be viewed in the context of the Regional Policy of the European Union. The main priority of this policy is to improve social and economic cohesion in the European Union by seeking to reduce disparities between European regions. Cities play a specific and prominent part in this respect. Cities are namely important sources of economic growth, whilst on the other hand they are faced with large social imbalances.

The direct purpose of the European City Statistics project is to collect comparable statistics at the European level on a large number of variables for a range of topics at three spatial levels: the administrative city, the greater city and the functional urban area (FUA).

Over 100 variables have been collected for the Urban Audit 2018.

This depends on the domain and individual indicator and can vary between 12 and 24 months.

Data is sent to Eurostat as soon as it has been validated within the European City Statistics team.

Different data sources are sometimes used for the devolved administrations in the UK leading to deviating definitions therefore, the comparability of data may be limited to some extent. More detailed information on sources and deviating definitions is available in the UK Metadata Report (see below link).

Where possible the European City Statistics team within the UK have used the same data source for variables in order to preserve a time series across the collection.

When there is a break in the time series due to methodology or boundary changes for a variable a flag of 'b' is added to the data file.

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.

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

Where possible data have been downloaded from the Office for National Statistics and other government department websites in order to reduce the burden of requesting bespoke datasets. Where this could not be achieved care was taken to ensure both value for money and any potential burden on data suppliers was taken into consideration.

The Urban Audit is an annual data collection.

This is ongoing dependent upon availability of release and publication of data.

Data validation was undertaken in the production of the data and by the European City Statistics project in the United Kingdom.
