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
