What it means for Impact Measurement

• A demo buyers can understand. Deprivation Lens shows where the spend lands in seconds, area by area or across the UK.
• Figures that stand up. Every number comes from a named official source, labelled with its year.
• Fair across the UK. Areas in England, Wales, Scotland and Northern Ireland can be compared on one scale.
• Safe to open up. The public site was security checked and hardened before go-live.
