 25 years after the fall of the Berlin Wall, the visible signs of division between east and west have largely disappeared from the city. As you can see here, the wall that once enforced the Iron Curtain appears most often as a backdrop for tourist photos and selfies. But if you look beyond the structure itself, the east-west partition is still very much alive. A plethora of social indicators, from income levels and unemployment to fertility and vaccination rates, and even travel destinations point to a shift towards less visible fault lines in Germany and indeed in Europe more broadly that may well shape the continent's future. Too often left to the margins, these boundaries are a critical aspect of my work as both a journalist and a sociologist. As this anniversary brings together those who witnessed the wall coming down with those who are only now coming of age, we should all mark this occasion by thinking how we might address these more subtle but no less divisive lines of separation.
