DATA from the 2021 census has shown how the Duchy's population has increased since 2011.

New data from the Office for National Statistics (ONS) has shown that Cornwall's population size has increased by 7.1%, from around 532,300 to 570,300 from 2011 to 2021.

According to the Office for National Statistics: "This is higher than the overall increase for England, where the population grew by nearly 3.5 million to 56,489,800.

"At the other end of the scale, the Isles of Scilly have seen a fall of 4.7%."

This increase in population saw Cornwall move up one place to the third for total population size out of 309 local authority areas in England.

The 7.1% increase across Cornwall is actually lower than the rest of the South West which saw an increase of 7.8%.

When it comes to population density, Cornwall ranked 12th across the 30 local authority areas in the South West, which equates to a football pitch-sized area of land being occupied by a single person.

For context, Tower Hamlets in London is the most densely populated local authority in England, with each football pitch-sized area of land being occupied by 112 people.

On the other end of the scale, Eden in Cumbria's density works out as around five football pitch-sized areas of land per resident.

The data also shows that the South West has gotten older, with the largest age group in the region being made up of people between the ages of 55-59 years old, as opposed to 45-49 back in 2011.

Cornwall has also seen an increase of 25.1% in people aged 65 years and over, an increase of 1.7% in people aged 15 to 64 years, and an increase of 4.3% in children aged under 15 years.

Across the country, the largest age group in England is made up of people between the ages of 30-34 years old.
