As of March 2022, we have:

  • comprehensive data including party affiliation, constituency, and service dates for all MPs, 1970 onwards (example for the 2010-15 Parliament);
  • comprehensive data including party affiliation, constituency and service dates for all members of the Scottish, Welsh, and (current) Northern Irish devolved assemblies (example for 2011-16 MSPs);
  • near-comprehensive data including service dates and constituencies for most MPs from 1820-1970, with some omissions and ambiguities (validated complete from 1880, imperfect before that date), plus party affiliations for members from 1923 onwards.

Prior to 1820 service dates are not yet available, but we do have some form of Wikidata entries representing the majority of known historical MPs, and improved coverage for some early periods:

  • 1660-1820 - basic items with a link to History of Parliament records for all MPs, but no dates of service or constituencies
  • 1640-1660 - only incomplete coverage of the Civil War and Commonwealth periods
  • 1509-1629 - constituency and parliamentary terms for all MPs recorded by the History of Parliament (which is incomplete in this period), but no exact dates of service
  • 1422-1504 - very incomplete coverage of the fifteenth century
  • 1386-1421 - constituency and parliamentary terms for all MPs recorded by the History of Parliament (which is incomplete in this period), but no exact dates of service
  • prior to 1386 - very incomplete coverage
  • pre-Union Scotland or Ireland- very incomplete coverage

In total, this represents 28,600+ individual MPs, or 30,900+ including members of the devolved parliaments plus pre-Union Ireland and Scotland.

Coverage of the House of Lords is less comprehensive, though the majority of current Lords members are listed with term dates.

As a side project, we have included coverage for all ambassadors and high commissioners since ~1800; this has substantial overlap with MPs, particularly in the early part of the period.
