More or Less

The crime rate in London has been cropping up regularly on social media and in political discussions - US president Donald Trump has claimed that crime in the city is ‘through the roof’.
But what does the data tell us?
Professor Matt Ashby, from University College London’s Centre for Global City Policing, has put together statistics that allow you to start to compare crime rates between cities around the world.

That evidence shows London in a different light, in terms of murder and other violent crimes.

As the 2026 World Cup approaches its end, what is the biggest factor in who wins? Is it extraordinary moments of attacking magic? Gritty defensive organisation? Or is it all just a question of luck and random chance?

We look at how mathematicians and analysists make sense of chaos, xG and unpredictability in the beautiful game.

Recently a post did the rounds on Twitter, claiming that people who play tennis live on average 9.7 years longer than people who play other sports.
The figure comes from a recent analysis of people's exercise habits in Denmark.
But not everyone on Twitter was convinced. Tennis is a sport that in many countries is expensive to play and so attracts wealthier players. Couldn't it be the players' socio-economic status driving the trend?
We speak to medical statistician Adam Jacobs, to understand what the study in question can, and cannot, say for certain.
