Sport England data
Winchester (8.87 per cent), York (8.72 per cent), Wandsworth (8.62 per cent), Brighton and Hove (8.59 per cent), Norwich (8.57 per cent) and Rugby (8.54 per cent) have also made it into the top ten.
Exeter came last in the league table, with just 3.91 per cent of adults saying they swam at least once a week.
The data was released to encourage people to get in the pool for Swim22, which gives swimmers three months to swim 22 miles in their local pool, either by themselves or by splitting the distance with teammates. The event starts on February 22.
‘Swim22 is a great way to support Diabetes UK’
Todd Harris, Diabetes UK Fundraising Manager, said: “We want these results to challenge everyone to have a go at swimming in their local pool – and the fact Swim22 runs for three months means there is plenty of time for solo swimmers or teams to cover the distance.
“Swimming is a great way to keep physically active, which alongside healthy eating, is really important for preventing Type 2 diabetes or helping manage diabetes if you already have it.
“Clearly, Poole is a well-named town, and it is great to see so many people already swimming there. And as many people clearly find it enjoyable, it is something they are more likely to stick with in the long run. We have heard from lots of people who have used the three months of Swim22 to form a new lifelong fitness habit, and often lose a lot of excess weight in the process.
“And the event is a great way to support Diabetes UK too. Money raised through sponsorship will help us to fund research, campaign on key issues, and offer education and support to more of the 4 million people in the UK who are living with the condition.”
