Isles of Scilly

Key figures

9 of 10 measures have a published figure for Isles of Scilly · no figure for band d council tax as a share of pay. Each figure is the publisher’s own, for the period named beside it.

Why the population is changing

The ONS breaks the year’s population change into its components (Year to mid-2025). These are its published figures for Isles of Scilly, not our estimates.

• 14 births and 23 deaths: natural change reduced the population by 9.
• Moves within the UK (net) reduced the population by 60.
• International migration (net) reduced the population by 17.
• The ONS’s balancing item (“Other”, mainly armed forces and prisoner adjustments) added 2.
• Altogether the population fell by 84 over the year (the sum of the components above — our addition of the ONS’s published figures).

Each component is a series in its own right: births, deaths, moves within the UK and international migration.

Population change, year by year

The same decomposition for every published year in Isles of Scilly: births and deaths, net moves within the UK, net international migration, and the ONS’s balancing item.

Years to mid-2024 are the ONS’s rebased back series, made consistent with Census 2021 — its figures deliberately differ from the estimates published at the time. Every cell is a published figure; the total is the sum of net moves, natural change and other, which is our addition. A dash is a year the source does not publish for this area, never a zero.

Rates per 1,000 residents

The same population flows, adjusted for Isles of Scilly’s size, so they can be compared with any other area’s: each year’s flow divided by the population that mid-year, times 1,000.

A Civometry calculation, not a published figure: ONS publishes these flows and the population, but not the rates. Net rates are signed — below zero means more left than arrived. Rates are crude, not age-standardised, so areas with very different age structures still differ for reasons size cannot remove. Each link shows the full recipe and every year.
