Study Number 7724 - European Quality of Life Time Series, 2007 and 2011: Open Access

Legal Agreement on Condition of Use

In accordance with the depositor's wishes, these data were made open (no registration required). The UK Data Archive approved the decision to open the data.

Privacy Impact Assessment

The UK Data Archive follows best practice guidance in the field of social science data sharing, taking its lead from the Office of National Statistics. Data owners and producers are responsible for signing off on confidentiality, following their own in-house protocols. For example, each government department may have its own classification system for data release of data and follow a bespoke standard. The Archive undertakes further routine checks on data to ensure the data meet our own confidentiality standards and match the type of licensing selected by the data depositor. Key survey variables are identified and checked for basic disclosure risk following the UK Government Statistical Service (GSS) Disclosure Control Guidance for Microdata Produced from Social Surveys. Release of other kinds of data, such as textual data, is approved by the owner/producer and is further checked by the Archive for disclosive information that may potentially be detrimental to meeting the original terms and conditions of the research and participant consent. The Archive follows the Information Commissioner's Office (ICO) Anonymisation: Managing Data Protection Risk Code of Practice.

UK Data Archive Processing Standards

The data were processed to the UK Data Archive's A* standard. This is the Archive's highest processing standard. This means that an extremely rigorous and comprehensive series of checks was carried out to ensure the quality of the data and documentation. In addition, any data or documentation that breached confidentiality rules were altered or suppressed to preserve anonymity (see Privacy Impact Assessment statement above).

Data conversion information

From January 2003 onwards, almost all data conversions have been performed using software developed by the UK Data Archive. This enables standardisation of the conversion methods and ensures optimal data quality. In addition to its own data processing/conversion code, this software uses the SPSS and StatTransfer command processors to perform certain format translations. Although data conversion is automated, all data files are also subject to visual inspection by a member of the Archive's Data Services team.

With some format conversions, data, and more especially internal metadata (i.e. variable labels, value labels, missing value definitions, data type information), will inevitably be lost or truncated owing to the differential limits of the proprietary formats. A UK Data Archive Data Dictionary file (generally in Rich Text Format (RTF)) is usually provided for each data file, enabling viewing and searching of the internal metadata as it existed in the originating format. These files are called: [data file name]_ukda_data_dictionary.rtf

Important information about the data format supplied

MS Excel (*.xls/*.xslx)
SAS (*.sas7bdat and *.sas)
MS Access (*.mdb/*.mdbx)

Conversion of documentation formats

The documentation supplied with Archive studies is usually converted to Adobe Portable Document Format (PDF), with documents bookmarked to aid navigation. The vast majority of PDF files are generated from MS Word, RTF, Excel or plain text (.txt) source files, though PDF documentation for older studies in the collection may have been created from scanned paper documents. Occasionally, some documentation cannot be usefully converted to PDF (e.g. MS Excel files with wide worksheets) and this is usually supplied in the original or a more appropriate format.
