In a recent speech to the UN, US president Donald Trump set out some remarkable figures on the proportion of inmates in European prisons who were foreign nationals.

Citing statistics from the Council of Europe, he references Greece, Germany and Austria, as having rates around 50%.

“In Switzerland, beautiful Switzerland,” he said “72% of the people in prisons are from outside of Switzerland.” These numbers are correct, but why are the percentages so high – particularly in Switzerland?

Tim Harford speaks to Professor Marcelo Aebi, a criminologist from the University of Lausanne, who wrote the prisons report for the Council of Europe.

Tim Harford investigates some of the numbers in the news. This week:

The Daily Mail says that over half of the UK population live in households that get more in benefits than they pay in tax - is it true?

Do some billionaires earn more in a night than the population of Bournemouth earns in a year? New Green leader Zack Polanski seems to think so - we scrutinise the figures.

Are older generations getting smarter?

Have 77% of Gen-Z brought a parent along to a job interview? Really?

When you follow the news, particularly in countries like the UK and the US, it sometimes feels like people are less optimistic about their lives than they were in the past. But a new piece of analysis from polling company Gallup suggests this might just be the local view, not the global one. Using data from the Gallup World Poll, it suggests that “people in more countries are living better lives and expressing more hope for the future” than at any point in the last decade.

Tim Harford speaks to Gallup’s Benedict Vigers, who wrote the report, to understand what improvements in the “global median for thriving” really means. If you’ve seen a number in the news you think we should look at, email the team: moreorless@bbc.co.uk

In early February 2025, something strange started happening across US government websites.

Decades of data began disappearing from webpages for agencies such as the Centres for Disease Control and Prevention, the National Institutes of Health and the Census Bureau. In many cases the entire website went dark. Within a few days some 8,000 government pages and 3,000 datasets had been taken down. Since then, many have been reinstated - but some have not. We speak to Professors Maggie Levenstein and John Kubale to find out why this data was taken away, and why any of it matters.
