We aim to update this dashboard once a year, in line with the Office for National Statistics’ data release for England and Wales. Data for Scotland and Northern Ireland is published earlier in the year, and so more up-to-date figures may be available. MPs and their staff can contact the Commons Library with queries about updates.
