What this data can and can’t tell you
- “Essex’s towns” and “England’s towns” mean their built-up areas. Census comparisons pool every built-up area in Essex (or England), summed the same way as Blackmore’s figures, so households in open countryside are left out.
- 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.
