New: I've published the geographical templates behind the UK cartogram maps shared here recently. There are four geopackage files for MSOAs, local authorities (both lower-tier and upper-tier), and constituencies. All on the @commonslibrary github here: github.com/houseofcommonslib…

I've just published two articles on the 2024 GE, on marginality and turnout (links below in reply). Especially happy with this chart, which shows the clear correlation between turnout and winning party. Almost all LD and Con wins were in higher-turnout seats.

The census took place in March 2021 during the pandemic. For some of the questions, in particular, this means it's unhelpful to present its findings in the present tense. ons.gov.uk/employmentandlabo…

Working from home is heavily concentrated in the SE and London, Inner London especially. Interestingly this suggests that many people are paying a lot to live in central London despite not needing to do so for length-of-commute reasons.

6% of trips used more than one mode of transport, and around two-thirds of these multi-modal trips started with walking (60%) and were followed by public transport modes #NationalTravelSurvey #England gov.uk/government/statistics…

Grave of the Fireflies, a Studio Ghibli classic, is coming to Netflix on September 16. Based on Akiyuki Nosaka's short story and directed by Isao Takahata, orphaned siblings Seita and Setsuko fight for survival amidst the devastation in post-war Japan.

Unfortunately, for travel from 1 October onwards, LNER are extending their 'fares trial', and discontinuing affordable/flexible/refundable Off-Peak fares on ALL their longer-distance flows.
Replying to @greensignallers
@greensignallers @seatsixtyone @MartinSLewis Alert! Alert!! LNER have extended their "no off peak fares at all" thing to virtually their entire route from I think 30th September - thus blocking the Haymarket loophole...

Couple of thoughts on the migration stats which came out yesterday and were covered in The Times today. Most strikingly, they show a fall in applications for work visas in health and care, which is where policy was recently changed to disallow bringing dependents. (1/7)

If you're reading the Library briefing on the 2024 general election results: commonslibrary.parliament.uk… and thinking that's marvellous, but I'd also like to see it sliced and diced by some other axis, all the same data is available as a @datasetteproj here: psephology-datasette-f3e7b1b…

Just a word of thanks to the dedicated colleagues involved in this project - gathering, verifying and processing data, designing websites, keeping everyone informed, and providing advice. Too many to name here, but all crucial contributions.
