The story everyone knows about the English seaside is that it is dying. Boarded-up arcades, young people gone, populations draining away.
The first two may be fair. The third is not true, and our data says so plainly.
They are all growing
| Coastal authority | 2001 | 2024 | Change |
|---|---|---|---|
| Tendring | 138,802 | 156,759 | +12.9% |
| Thanet | 126,750 | 142,691 | +12.6% |
| East Lindsey | 130,654 | 145,183 | +11.1% |
| Great Yarmouth | 90,945 | 100,529 | +10.5% |
| Torbay | 129,965 | 140,126 | +7.8% |
| Hastings | 85,392 | 91,219 | +6.8% |
| Isle of Wight | 132,925 | 141,660 | +6.6% |
| North Norfolk | 98,495 | 103,217 | +4.8% |
| Blackpool | 142,270 | 144,191 | +1.4% |
Every English coastal authority in that list has more residents than it did in 2001. Thanet, Great Yarmouth and Tendring have grown by more than a tenth. Even Blackpool, the usual shorthand for seaside decline, is marginally up.
The places genuinely losing people are elsewhere: Scottish islands, west Wales and post-industrial Clydeside. Not the English coast.
So why does the decline story persist?
Because the people are real but the prosperity is not, and population growth measures the first while everyone talks about the second.
The Chief Medical Officer devoted his entire 2021 annual report to coastal communities, and the findings are stark. Coastal communities carry a high burden of physical and mental ill health, with lower life expectancy and higher rates of most major diseases.
The age profile explains a great deal of it. In smaller seaside towns 31% of residents were 65 or over in 2019, against 22% in comparable non-coastal towns. Retirement in-migration adds people while pushing the median age up, so a town can grow and hollow out at the same time.
The bit that compounds
Coastal areas have greater health needs and fewer staff to meet them. The same report found coastal communities have 15% fewer consultants, 14.6% fewer postgraduate medical trainees and 7.4% fewer nurses per patient than the national average.
Professor Whitty called for a cross-government national strategy, describing the situation as one that will worsen without deliberate intervention.
Why the numbers mislead
This is the clearest case on this site for why a population figure needs its context. Read the growth column alone and the English seaside looks healthy. It is not: it is getting larger and older simultaneously, and the second matters more than the first.
A number tells you what happened. It does not tell you whether that was good.
