<p>Tim Harford investigates some of the numbers in the news. This week:</p><p>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. </p><p>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. </p><p>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. </p><p>And an answer to a question that literally only one person was asking: how many football pitches would fit inside Wales? </p><p>More or Less is the programme that looks at numbers and statistics in news and in life.
