All statistics produced by the department are designated as 'official statistics' and a subset of these are designated as 'National Statistics'. As such, they are produced in line with the three pillars and associated principals and practices set out in the UK Statistics Authority's Code of Practice for Statistics.
Departmental statistical statements and policies
As well as complying with the Code of Practice and its supporting protocols, the department further demonstrates its commitment to the Code of Practice by publishing a series of supporting statements related to its use of administrative data, publication strategy, confidentiality arrangements, revisions policy, customer service and complaints procedure.
These are included in the following document: Code of Practice for Statistics - supporting statements
Data collected by NISRA and PSNI is processed by DfI Analysis, Statistics and Research teams in order to provide data to support the functions of DfI. More information on this data collection, and the rights of those individuals within these datasets can be found on the NISRA website and the PSNI website.
Review and assessment of statistics
The UK Statistics Authority, which was established as part of the Statistics and Registration Service Act 2007, is now responsible for the development and maintenance of the Code. Under the Code of Practice, statistics produced by the department are subject to regular review and assessment in order to verify that they are fully code compliant. Details of recent assessments are provided in the following documents:
