We've built a data explorer for every neighbourhood receiving funding through the Pride in Place programme. You can map, zoom in, and compare every neighbourhood with data on deprivation, need, social capital, and social infrastructure. You can download it all

It's completely free to use, too.

3.5. Council Tax Stock of Properties Added September 2025 The VOA has been moving its Council Tax work onto a new, modern, operating system. The data provision for statistics is also being updated and iterated as part of this work. As a result, we plan to release a shorter publication containing key headline stock figures for each billing authority, broken down by band, during autumn 2025, rather than the full suite of official statistics we typically publish. This means that tables on insertions, deletions and time series, will be available later, once the data provision updates are completed and assured for official statistics production. We will provide a further update on the timeline for publishing insertions and deletions, as well as plans for changes and improvements to the overall publication, in due course.

Indefinite delay to the next release of detailed tables in the Valuation Office Agency's Council Tax Stock of Properties statistics – a valuable source of small area attributes for housing stock in England and Wales www.gov.uk/government/s...

Image of a poster to be presented at the Royal Statistical Society conference in Edinburgh, September 2025. The main point is to generalize the idea of a ternary plot to handle 4-part compositions, by showing views through the triangular faces of a tetrahedron. The data shown are vote counts from England, Scotland and Wales in the UK General Election of July 2024.

At next week's RSS conference I'll be presenting a poster (a first for me...it's about time!)

"Tetraplot displays of UK General Election results" shows how to graph GE 2024 vote shares across 4 parties in a useful way.

Huh. Just discovered that a photo of mine (of the University of Michigan) is used on 6 English Wikipedia pages and a dozen in other languages. I forgot I ever uploaded it.

How do leasehold transactions vary by constituency? An annotated map of the percentage of sales that were leasehold by constituency in 2024 in England and Wales. Annotations explain: 23% of residential property sales were leasehold in England and Wales in 2024. 98% of flats were sold leasehold, compared with only 6% of houses. There was also a lot of variation between constituencies. There were some leasehold 'hotspots' in areas where it's more common for houses to be sold leasehold, including parts of the North West and Yorkshire. Other hotspots are areas where flats make up a large proportion of overall sales, like central London.

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.

Leasehold housing in England: Statistics This briefing explores statistics on leasehold housing stock and transactions, in the context of ongoing reforms to the leasehold system.

I've published a new briefing bringing together the stats on leasehold housing in England (and a bit in Wales). Featuring:
- MHCLG data on leasehold stock
- Trends in transactions over time and for constituencies
- Experiences of leaseholders

I've now written a piece about why the internet hates my apostrophe, which you can read here: www.ft.com/content/48d4... Huge thanks to everyone who replied to me about it!

Very off-topic - but worth noting that this kind of granular local authority data is not long for this world, with county/district areas set to merge up into larger unitaries. North Yorkshire/Cumbria LAs likely to be more typical of the future size.

Has an impact on our local understanding.

Using time series graphs to make causal claims be like

County council have now sent round a leaflet about this - almost entirely promoting their preferred two-council option, with only a cursory mention of the rival three-council option which is also being consulted on (that most districts support)

Today we launch an internal expression of interest for this new Permanent Secretary role. It closes on 21 July. This will be open to existing Directors General and Permanent Secretaries. This vital role will be responsible for leading the ONS' operational business and restoring much needed trust and confidence in the department. In parallel we have also begun the process to find the next National Statistician and will shortly appoint a search partner to support us on this critical appointment leading our national government statistical service. Last month Sir Robert Chote informed the Cabinet Office of his intention to step down as UKSA Chair in the autumn to take up the role of President of Trinity College, Oxford. A campaign to appoint his successor will be launched within the next few weeks.

I don’t get much engagement on my posts about stats but I’ll press on as I think its important. So it seems that we are about to have a lot of leadership churn with Robert Chote stepping down early as chair of the Stats Authority whilst they also appoint other key roles 😬

More than a quarter of people think MPs expenses are one of the top three costs for government. A higher % than think the same for pensions or education.
