What we prove

Health and equity — applied to every commission

Health and equity are not policy silos. They are the standards against which we judge whether interventions worked at population scale — after sufficient time has passed for indicators to move and for communities to report what changed on the ground.

Health

We track outcomes with realistic lag: air quality and physical activity, injuries and preventable demand, mental health and wider-determinant profiles. Transport, housing, growth and skills policies all have health consequences — we make those traceable in official data.

Did exposures or behaviours shift in the populations the policy targeted?
Are health indicators moving in the claimed direction at city and neighbourhood level?
What did forums and polling reveal that administrative data missed?

Equity

Aggregate success can hide regressive impacts. We disaggregate by income, ethnicity, disability, age, tenure and neighbourhood deprivation. Jobs and income from growth programmes are read through this lens — who gained access, who bore new costs, and where disparities widened or narrowed.

Did benefits concentrate in already well-served areas?
Which cohorts saw gains in employment, mobility, housing stability or skills?
Do community accounts align with — or challenge — the statistical picture?

Geographic frame: cities & regions

Proof is always situated. Urban policies ripple across travel-to-work areas, housing markets and service catchments. DDPP analyses city cores alongside their surrounding regions so commissioners see spillovers — not just a map shaded inside one authority boundary.
