What this data can and can’t tell you
- “Powys’ towns” and “Wales’s towns” mean their built-up areas. Census comparisons pool every built-up area in Powys (or Wales), summed the same way as Llandrindod Wells’s figures, so households in open countryside are left out. The population trend compares with the whole county and nation.
- Estimates since 2021 are modelled. The ONS builds mid-year estimates from the Census, births, deaths and migration records. Llandrindod Wells’s trend uses the small areas (2021 LSOAs) with most of their people inside it: 5,596 people in 2021, against 5,429 in the built-up area.
- Small counts are blurred. The ONS adds small random changes to Census counts to protect privacy, so the same total differs a little between tables, and the shares of a small town can move by a point or two.
