* Before 2013: Unemployment Benefit or Jobseeker’s Allowance claimants only. n/a means no share was published for that year.
The Claimant Count is people claiming Jobseeker’s Allowance plus people on Universal Credit who are required to look for work. Before 2013 it counted only Unemployment Benefit or Jobseeker’s Allowance claimants, so earlier years are not strictly comparable. Universal Credit requires more people to search for work than Jobseeker’s Allowance did, so as it replaced older benefits from 2013, part of the rise in the count reflects that change rather than more unemployment. It is not the official unemployment rate, which comes from a survey. The latest month can be revised.

Child poverty
Children under 16 living in low-income families, 2024-25
| Year | Children | Share |
|---|---|---|
| 2021-22 | 49,645 | 22.4% |
| 2022-23 | 54,101 | 24.1% |
| 2023-24 | 54,031 | 23.7% |
| 2024-25 | 57,320 | 24.9% |
Figures for this county are the total of its district councils. A child is counted if their family’s income is below 60% of the UK median for that year and the family claimed Child Benefit plus at least one other benefit (Universal Credit, tax credits or Housing Benefit). The two measures can differ a lot: housing costs push the after-housing-costs figure far higher in expensive areas such as London. Figures are provisional and years before 2021-22 are not comparable, so the trend starts there.

Fuel poverty
56,925 households in fuel poverty, 2024
10.4% of 549,043 households · England 9.9%
Across this area’s 760 neighbourhoods, estimates range from 2.0% to 27.6%; 353 are above the England rate of 9.9%.
| Neighbourhood | Households | Fuel poor |

| Burnley 010D | 669 | 24.2% |
| Hyndburn 004F | 734 | 24.1% |
A household is counted as fuel poor if its home has an energy efficiency rating of band D or below and, after paying for housing and the energy it needs, its income is below the poverty line (60% of the national median). These are modelled estimates: the government advises using them for broad comparisons and to spot areas of particularly high or low fuel poverty, not to track year-to-year changes, so only the latest year is shown. Neighbourhoods are small census areas (lower layer super output areas) of roughly 1,500 people, named after their council and a reference number; their estimates are less certain than the council figure.

Average prices are HM Land Registry’s estimates for the whole area, adjusted for the mix of homes sold, not the price of any one home.

Sales counts are published about three months behind prices. In areas with fewer sales, figures can swing noticeably from month to month.

Housing and homelessness are district council responsibilities, so figures for this county are the total of its district councils; a quarter is shown only when every district reported it. Councils must help households threatened with homelessness within 56 days (prevention duty) and those already homeless (relief duty), and may house them in temporary accommodation while more settled housing is found. Figures for January to March 2026 were not submitted, so the latest available quarter is shown. Figures for January to March 2026 are provisional and may be revised. “Not published” means the council did not submit figures or MHCLG suppressed small numbers to protect households. No temporary accommodation figure is available for: October to December 2019, January to March 2020, April to June 2020, July to September 2020, October to December 2020, January to March 2022, July to September 2022, October to December 2022, January to March 2023, October to December 2023, January to March 2026.

These are casualties in collisions reported to the police on all roads in the council’s area, including motorways and trunk roads it doesn’t manage. Police forces have moved to an injury-based recording system that classes more injuries as serious, so the Department for Transport publishes an adjusted “killed or seriously injured” estimate to allow fair comparison between years; the trend uses the adjusted figure, and the road-user table uses figures as recorded. Rates are per billion miles driven by motor vehicles in the area.

* Inspection of a predecessor school (for example, before it became an academy).
Since 10 November 2025 Ofsted inspects schools under a renewed framework and publishes a report card grading up to eight areas on a scale of five points, plus whether safeguarding standards are met. Ofsted says these grades cannot be compared with grades from the previous framework, so they are shown separately. Graded inspections between 1 September 2024 and 9 November 2025 gave no overall grade (“Not judged”). Ungraded inspections check whether a school is still at its previous grade; the “Earlier inspections” figures use the last graded inspection.

| Ultrafast (100 Mbit/s or more) | 92.1% |
| Ultrafast (300 Mbit/s or more) | 91.6% |
| Gigabit-capable (1,000 Mbit/s) | 91.4% |
| Full fibre to the premises | 89.3% |
| Can’t get 10 Mbit/s | 0.4% |
| Can’t get decent broadbandfrom a fixed line or fixed wireless | 0.0% |
| 4G indoors from at least one networkshare of premises | 99.7% |

Figures for this county are the total of its district councils. These figures show what is available, not what people buy. “Decent” broadband means 10 Mbit/s download and 1 Mbit/s upload, the standard set by the broadband Universal Service Obligation. Full-fibre use is the share of all premises with a full-fibre connection in use. Mobile figures count the four networks Ofcom reports (EE, O2, Three and Vodafone) and are modelled predictions of signal strength; 5G figures use Ofcom’s high-confidence measure.

Figures for this county are the total of its district councils. A storm overflow releases diluted sewage into a river or the sea when sewers are overloaded, usually in heavy rain. Hours are the total time all spills lasted. Spills are counted the Environment Agency’s way: any discharge in the first 12 hours counts as one spill, and each further 24-hour block counts as another. 25 overflows discharge below the high-tide line or out at sea and are counted with the nearest council area. Compare every council, constituency and water company.
