Data table and workings
Published ONS table values from one 1997–2024 release, matched by exact source geography code. Table3 per-person values are retained, not recalculated from rounded totals. Source country/region references are the official published totals, not averages of selected councils.
Amounts are in cash prices for each year and include inflation. A rise does not by itself show an increase in purchasing power.
This is an average per resident, including children and retired people, not the income of a typical household, wages or wealth.
These are official statistics in development, combining administrative and survey inputs. The Annual Population Survey contributes to some components; it is not the sole source.
The 2024 estimates are provisional. Earlier years have been revised within this single release; no release editions are spliced.
The UK index compares each year with the UK average in that same year. It is not an inflation-adjusted income index.
Geography as published in the ONS 19 August 2026 release; exact source code retained. The workbook does not specify a separate local-boundary effective date.
The table retains the full reviewed history when the chart is shortened. Preset ranges end at this measure’s latest published period. Yearly windows count published annual periods; monthly windows count months. Gaps are never filled with estimates.

All usual residents aged 16 and over
21 March 2021, residents aged 16 and over. Includes full-time students in the corresponding work/unemployment categories. Not a current labour-market estimate or the usual 16–64 employment rate. Census took place during the coronavirus pandemic; furlough and lockdown affected answers. Ward counts sum complete official output-area best-fit membership; privacy adjustment can make totals differ slightly.
Published UK House Price Index average price, all property types and all buyers, not seasonally adjusted. Entire series comes from the 2026-07 official full-file release, preserving its historical revisions and exact area codes. It is a mix-adjusted average, not the median price paid.
Official local housing data feed. House prices are provisional, not seasonally adjusted; rents use the Price Index of Private Rents. Local short-term estimates are variable. Country references use only the explicitly country-coded ctry object, never the local place object.
Deprivation describes several kinds of disadvantage. It is not a measure of household wealth. A change in an area's ranking does not by itself show whether living conditions improved.
Use the age profile alongside school places and care capacity, and look at housing costs alongside pay. Then check whether local plans respond to the needs shown by the evidence.
