BRES counts jobs, not people (a part-time job and a second job count once each), so it runs above the Census count of people working here (117). Small areas are shared out to the town by where their Census 2021 workers were based; kinds of work are BRES industry divisions (SIC 2007), rounded. Wales’ towns: all jobs in its built-up areas.

Jobless claims in the Caerphilly council area are below England and Wales’ rate
Caerphilly’s rate was about 3.2% in 2019, peaked at 6.4% in May 2020 and has averaged 3.4% in 2026, against 4% across England and Wales. Claims everywhere stay higher than before the pandemic, partly because Universal Credit counts more people on low pay as looking for work.
The chart is the whole council area of Caerphilly, which Nomis publishes monthly; the figures above the line are for Deri’s built-up area. Claimant count: people claiming Jobseeker’s Allowance, or Universal Credit while required to look for work. Employment deprivation counts people out of work on Jobseeker’s Allowance, Employment and Support Allowance, Incapacity Benefit, Severe Disablement Allowance, Carer’s Allowance or the Universal Credit equivalents (Welsh Index of Multiple Deprivation 2025). The “most deprived tenth” compares areas within Wales only.
Claimant rate since 2015: people claiming Jobseeker’s Allowance or Universal Credit while looking for work, as a share of residents aged 16 to 64 (DWP, via Nomis).
How Deri spends its days: 54% of adults in work
Compared with Wales’ towns, 3% are full-time students (against 8%) and 9% are long-term sick or disabled (against 6%).

What this data can and can’t tell you
- The Census was taken in lockdown. Census day was 21 March 2021, during the third national lockdown: many people were furloughed or working from home, so fewer travelled to work, and journeys were shorter, than before the pandemic or since. The flows on this page show where people worked that spring.
- At home and no fixed place are one figure. In the workplace flows, ONS puts people who mainly worked at home and people with no fixed workplace (drivers, builders, care workers on rounds) at their home address, so the two can’t be told apart there.
- Towns are built-up areas. Deri here is ONS’s built-up area: the town as built, not its council district. A workplace on an estate or farm outside every built-up area counts as “outside any built-up area”.
- Jobs are counted where they are. BRES counts jobs at each workplace (employees and working owners, rounded by ONS), so a town with a hospital, university or big employer can have more jobs than working residents. Small areas are shared out to towns by where their Census workers were based.
- The benefits chart is the council area. Nomis publishes the claimant count monthly for councils back to 2013, so the line is Caerphilly as a whole; the claimant rate elsewhere on this page is Deri’s built-up area, from small areas.
