Policy domains

Where interventions happen — and where we stress-test them

DDPP analyses policy in four domains. These are levers central and local government pull: transport schemes, housing and place-making, economic growth programmes, and education and skills pipelines. Every domain is evaluated through the same proof lenses — health and equity.

Cities and regions sit at the centre. Domains feed in; health and equity are how we judge whether claimed outcomes manifested — for everyone, not just on average.

What we analyse

Transport

Modal shift, public transport, active travel, freight and streets — tested once journey and safety data have had time to move.

Housing & place

Affordability, tenure, density and regeneration — linked to neighbourhood stability and city–region housing markets.

Economic growth

Jobs, investment and productivity claims — stress-tested with jobs and income read through the equity lens.

Education & skills

Schools, adult learning and workplace training — including access barriers forums and polling often surface first.
