House of lords not representative, due to life peerages (being able to sit on lords for the rest of their lives.) So, it is very under-represented in terms of age. 54% of peers are over 70, and only 29 peers are under 50, and only two are under 39! Under representative when it comes to geography too, with 44% living in London and the south east of England. And, in gender, only 22% of political appointments since 1997 have been women. This is an argument for reform because the House of Lords is not representative in its current state. If its peers do not represent the general public in terms of age, gender, race, sexuality… etc, it will not reflect the views and outlooks of the electorate.
