Parliamentary Trends: Statistics about Parliament

This paper provides a summary of statistics about Parliament. It brings together figures about both the House of Commons and Lords; their membership and activities.
The aim is to provide comparisons over time, though periods may vary according to relevance and the availability of consistent data. Some are for parliamentary sessions (a parliamentary session begins each year with the Queen’s Speech) some by calendar year and some by financial year. This should be borne in mind when comparing different sets of information.
