Reading has a steady flow of new arrivals. Green Park, Thames Valley Park, the Royal Berkshire Hospital and the town centre bring in people from across Britain and abroad, often without an established social circle waiting for them. For local dating, that turnover is useful: there are regularly people who are settled enough to meet, but have not already known everyone for ten years.
The catch is that Reading can be socially fragmented. Someone might work beside the M4, live in Caversham and spend weekends with friends in London. Another person may have grown up in Tilehurst yet rarely cross town after work. Two people can live three miles apart while moving through completely separate worlds.
A smaller local dating pool is not a disadvantage if its members can realistically meet.That is why distance should be treated as a practical question, not just a number. Ask which side of the river someone lives on, whether they rely on buses or drive, and what “Reading” means to them. Caversham to central Reading is simple for many people. A vague Berkshire location may be anything but.
