I first did the constituency analysis quite a few years ago, but it's been good to bring it up to date. Some interesting patterns.

That's my mildly self-indulgent look back at the 2021 census as it played out in my own work. We will wait to see what the next decade brings, starting with the government's decision on the recommendation from the acting National Statistician.

A change in constituency boundaries not long after the first census releases could have put a spanner in the works, but ONS, NISRA and NRS have all published data for the new boundaries as well - making post-election analysis like this tool possible:

The census is behind a lot of our constituency data dashboards like this one - it's a rich source of local-level data and me and my colleagues do our best to help MPs make the most of it to understand their areas.

The 2021 census featured several new questions, including some on sexual orientation and gender identity 🏳️‍🌈🏳️‍⚧️. Mapping some of the early data on this was fascinating! commonslibrary.parliament.uk/2021-census-...

It feels like a very long time since I wrote the first edition of this, our briefing on preparations for the 2021 census in England and Wales.

Planning for a census starts years in advance, usually featuring a consultation on topics.
