💫 We’re launching the Centre for British Progress

Our founding essay: Rediscovering British Progress is a case for growth that drives shared progress, rooted in Britain's values and industrial heritage.

It all starts with a postcard from 1870 👇

After months of waiting, dead excited to give this a read. The rest of @unlearnecon.bsky.social's stuff is excellent, I doubt this will be any exception.

Measurement of urban vitality with time-lapsed street-view images and object-detection for scalable assessment of pedestrian-sidewalk dynamics Principles of dense, mixed-use environments and pedestrianisation are influential in urban planning practice worldwide. A key outcome espoused by thes…

In Cambodia, half the operations to detect active cases of tuberculosis have halted.

They estimate it has led to around 100,000 people missing screening, 300 drug resistant TB cases going undiagnosed, and 10,000 drug susceptible cases going undiagnosed.

Our analysis can be transferred to study urban vitality, and what supports it, in the global context.

...even in radically different contexts, vitality does seem to be cultivated in dense, diverse environments with short blocks and more than one kind of amenity. But, as our imagery analysis also tells us, they might also attract more road traffic the same way.

By combining that with openly available data that exists in a standardised way all over the world, we test the association between vitality and neighbourhood characteristics in an African city for the very first time and find...

In our new ISPRS Journal of Photogrammetry and Remote Sensing paper, we use cheap, easy to deploy cameras to capture time-lapse images in Accra, Ghana and develop a measure of urban vitality that works in pretty much any context.

But cities aren’t petri dishes, and empirically checking big claims about what makes for a vibrant street hasn’t been easy. Even with a new abundance of data and analysis, studies have only really looked at high- and middle-income countries using highly specialised bits of evidence.

...social and pleasant. In other words, a flywheel effect for creating a thriving urban space.

It’s generally assumed that vitality depends on the same characteristics many urbanists prize across the globe: dense, diverse, walkable, mixed-use environments.

What makes a city street appealing?

For seventy years, one school of thought has had the following answer: other people. “Urban vitality” is broadly what planners call it when streets and neighbourhoods have footfall spread out throughout the day, with the upshot of being safer, more prosperous...

🚨 New paper 🚨 A method for measuring urban vitality and relationship to street-level characteristics using time-lapse images, that scales globally. 70 years post Jane Jacob's writing about vitality, we show, for the first time, the relevance to African cities: www.sciencedirect.com/science/arti...

Thank you, Jimmy Carter.

This chart is on a log scale. This year there have been just 7 cases of guinea worm.

A major new report from @centreforcities.bsky.social calls for the Government to take much bolder action on reform to be sure to achieve its goal of 1.5 million new homes this Parliament!

I love how every single UK voter focus group is all 'we don't want more identikit posh boys. We need a change', and then you show them whoever looks the most like Tom Tugendhat and they go 'yeah, something about him says "Prime Minister", you know';
