More than half of England’s coastal communities could see a decline in the number of residents aged under 30 by the year 2039.
Analysis by BBC News of population projections has found seaside towns in northern England could see the biggest decline in under-30s.
The Parliamentary Group for Coastal Communities said funding cuts meant seaside towns were “being left behind”.
The government said it had invested more than £200m in costal communities.
The coastline in England is home to some of the most beautiful but also poorest places in England.
Some young adults living in the North Yorkshire town of Scarborough said they struggled to envisage a future for themselves living by the sea.
“There aren’t many career options in Scarborough,” said 24-year-old Kayleigh Wilkinson.
“You either work in a care home like I do, or you work in a shop.
“That’s one of the many reasons why people my age are already leaving to work in bigger cities like York and Leeds.”
According to population projections produced by the Office for National Statistics (ONS), Scarborough could see a 10.5% fall in the number of people under 30 living in the area by 2039, meaning a potential loss of some 9,000 young adults over the next two decades.
Ryan Broadbent, 21, moved from Scarborough to Leeds to study at university and said he could not see himself returning to the town.
“If you spend £30,000 on going to university the last thing you want to do is move back to a place where you can only find a low skilled job,” he said.
“Its not just jobs, there’s very little to do at the weekend for young people. We were promised a multi-screen cinema in Scarborough but that hasn’t happened.”
Twenty-year-old Reece Wilde was more optimistic about the future of the town, having just opened a cafe in the centre of Scarborough.
“I love this place and I think there are positive things happening,” he said.
“There are people like me setting up independent bars and coffee shops.
“But what Scarborough and other seaside places need to do is think of what they can offer people all year round, instead of just in the summer.”
What could happen to the population of England’s coastline?
BBC News has analysed the population projections made by the ONS for 75 local authorities in England with a coastline.
- More than half of the local authorities could see a fall in the number of residents under the age of 30 by the year 2039
- The biggest decline in the number of under-30s could be in the north of England, where every local authority with a coastline, except Liverpool, might see a fall in the number of young people
- Collectively northern seaside communities might see a reduction of 200,000 under-30s over the next two decades
- In contrast, coastal authorities in the south, such as Bristol (+13%), Canterbury (+6.4%) and Southampton (+4.7%) could see substantial rises in the number of young people

It said most seaside towns still relied on tourism but many in the future would need to diversify their economies.
Mike Hill, the Labour MP for Hartlepool and chair of the All Party Parliamentary Group on Coastal Communities, said seaside towns such as his were already creating new jobs.
“In my town we’ve created high-skilled well-paid jobs in sectors such as wind energy and carbon capture technology,” he said.
“But there is no getting away from it, these population projection figures are frightening, and without action could signal the death of some coastal towns.
“Government austerity and the underfunding of seaside towns is at the heart of the reason why these communities feel like they’ve been left behind.”
Responding last month to the House of Lords findings, the Department for Housing, Communities and Local Government said it acknowledged coastal communities were “comparatively more deprived”.
But it said regenerating coastal towns was a complex issue and that by the next year the government would have invested more than £220m in projects based in coastal communities that were already having tangible results.
