What the Office for Statistics Regulation wrote
“Overall, we consider that ONS has used the most reliable data source to produce the combined measure: the self-completion module of the Crime Survey for England and Wales (CSEW).”
“ONS publishes data on incidents of domestic violence in its Nature of crime: violence data tables, and detailed incidents data are available to researchers through ONS’s Secure Research Service and the UK Data Service.”
“While we welcome the range of metrics included, we have asked the Home Office to consider publishing additional supporting information on the metrics, data sources and data quality to support public understanding.”
“We note that, because the measure is published as official statistics in development, it does not yet meet the same quality standards as other CSEW estimates, which are published as accredited official statistics.”
