This is a case study for Principle V5: Efficiency and proportionality.
The Department for Work and Pensions (DWP) introduced Stat-Xplore, an open data tool which provides a guided way to explore DWP benefit statistics and helps to ensure that DWP statistical data is used, re-used and understood by a wide range of users.
Stat-Xplore currently holds data relating to 16 different DWP benefit programmes with plans to extend this to others in the future. The data on Stat-Xplore is the same data used in DWP statistical publications, so it does not impose any additional burden or require any additional supply of information from DWP sources, making efficient use of the statistical data DWP already holds.
DWP data on Stat-Xplore is available made in a number of ways to suit many user types, (including the Enquiring Citizen, Information Forager and Expert Analyst) with a helpful user guide, an interactive tour and extensive metadata provided to support users get the most value out of the data available.
The data contained in Stat-Xplore draws on recognised standards, classifications, definitions and methods. For example, many of the data sets draw on standard geographical units, and data perturbation/statistical disclosure control is applied to avoid the release of confidential information.
In conjunction with statistical publication consultations, user feedback and queries relating to Stat-Xplore datasets help DWP statisticians to determine whether new or extended data requirements are needed, thereby helping to inform decisions concerning the possible impacts of changing data requirements against their potential value.
Stat-Xplore has been upgraded to better meet user needs since its inception. User feedback has informed the further development of:
- Ready-made tables available for most sets of benefit data, for ease of use
- User defined tables which can be saved in a variety of formats (Excel, CSV, XML, ZIP), with additional large table functionality available to registered users
- Derivations – allowing users to create new calculated items within a table such as adding together values in other columns or using mathematical and statistical functions
- Linked data visualisations for 5 key benefits, hosted directly onto Stat-Xplore
- Mapping – a relatively new feature which allows users to view results from geographical fields inside an interactive map
- Open Data API – Registered users also have access to all datasets via the Open Data API. Users can build their own third-party interactive reports and applications that retrieve data directly from Stat-Xplore and automatically update every time DWP releases new data. The API also caches new requests to make the future retrieval of the same data much quicker
Stat-Xplore makes and is a valuable resource which makes efficient use of DWP statistical data and promotes its re-use both within DWP and more widely. Users access is well supported through extensive guidance, recognised standards, classifications and metadata. The analysis of users’ queries also supports DWP statisticians in determining whether value can be added to DWP statistics by adding new or extending existing data requirements.
