Lauren Leek @laurenleek.eu · 01/09/2026True, also surprised me too. But arrivals ≠ spend and France’s economy is so huge and diversified (Airbus, luxury goods, ag, nuclear) that tourism gets diluted as a %. Countries hit 20%+ tourism GDP by having not much else really. 010

Full piece, with the maps, the Moran's I and the regressions (obviously): open.substack.com/pub/laurenle...open.substack.comThe Great British Clubhouse Is Still Standing. Nobody's In It, Least of All Where It's Needed MostI tried to measure the decline of British community life by counting clubs. That was the wrong place to look. What’s disappearing is participation especially where deprivation is high. 061
Lauren Leek @laurenleek.eu · 29/06/2026And it's unequal. Convivial clubs cluster in comfortable areas; food banks and mental-health charities in deprived ones. Resulting in that in richer Britain, community means joining and n poorer Britain, it means need. 162
