Source selection
We prioritise original UK government publications, official statistics and primary research for claims about national policy and labour-market patterns. We may also cite academic work, professional bodies, employers, recruitment organisations and news reporting where they add relevant evidence. Their interests and methods are identified where material.
Claims and uncertainty
We distinguish observed data from projections and survey responses. A source’s authority applies only to what it actually measured. We do not infer causation from correlation or treat technical exposure as confirmed workplace adoption. When populations or definitions differ, we say so and avoid presenting them as directly comparable.
Statistics and dates
Important statistics are accompanied by a source link and, where available, publication date, reference period, population and geography. Projections remain projections. Editorial examples are labelled as examples and are not represented as measured outcomes.
Updates and corrections
Pages display their last research check date. We review evidence when a new primary source materially affects a conclusion or when a factual error is identified. Corrections should be made transparently and should not erase the context needed to understand an earlier version.
