What this data can and can’t tell you
- “South Yorkshire’s towns” and “England’s towns” mean their built-up areas. Census comparisons pool every built-up area in South Yorkshire (or England), summed the same way as Rawmarsh’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. Rawmarsh’s trend uses the small areas (2021 LSOAs) with most of their people inside it: 19,576 people in 2021, against 18,892 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.
