What this data can and can’t tell you
- The Census was taken in a lockdown, in term time. 21 March 2021 fell in term time, and students were asked to give their term-time address, so most were counted where they study. Some may have been living with family that day.
- “Gwent’s towns” and “Wales’s towns” mean their built-up areas. Census comparisons pool every built-up area in Gwent (or Wales), summed the same way as Abersychan’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. Abersychan’s trend uses the small areas (2021 LSOAs) with most of their people inside it: 7,040 people in 2021, against 7,495 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.
