Test Valley

Key figures

16 of 16 measures have a published figure for Test Valley. 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 Test Valley, not our estimates.

• 1,205 births and 1,251 deaths: natural change reduced the population by 46.
• Moves within the UK (net) added 524 people.
• International migration (net) added 45 people.
• The ONS’s balancing item (“Other”, mainly armed forces and prisoner adjustments) added 6.
• Altogether the population grew by 529 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 Test Valley: 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 Test Valley’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.

Pay against housing costs

How pay in Test Valley moved over its latest published year, beside how the cost of buying and renting moved over theirs. The three series come from different publishers on different timetables, so each row covers its own year, named in the row.

average private rent rose faster than pay over these periods.

Levels are the publishers’ own (ONS ASHE median annual pay for full-time employees living in the area; HM Land Registry UK House Price Index; ONS Price Index of Private Rents). The percentage changes are Civometry arithmetic on the two published values in each row. Pay is a survey of employees and says nothing about a particular household; one year is weather, not climate.
