What this data can and can’t tell you
- “Somerset’s towns” and “England’s towns” mean their built-up areas. Census comparisons pool every built-up area in Somerset (or England), summed the same way as Martock’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. Martock’s trend uses the small areas (2021 LSOAs) with most of their people inside it: 4,133 people in 2021, against 4,079 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.
