Debunking the claim that migrants will get half of new homes

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

The Daily Express claims that ‘Migrants will get half of all new homes’, based on a calculation from the Conservatives. We explain why that’s not what the numbers say, and ask what the Conservatives own record on migration and housing tells us.

Does one in five Welsh pupils leave school functionally illiterate? We take a dive into the world of Welsh education and find the numbers tell a different story - but not an encouraging one.

Accusations are flying about who’s responsible for the UK’s high borrowing costs. Does Liz Truss still cast a shadow over the bond market? Is Labour infighting to blame? Or are we missing the economic wood for the political trees? Duncan Weldon has the answers.

And an answer to a question that literally only one person was asking: how many football pitches would fit inside Wales?
