ONEMODEL
A full-system socioeconomic digital twin connecting people, families, dwellings, businesses, governments, infrastructure, and markets so policy and investment choices can be followed through the economy and into people’s lives.
ONEMODEL began as CANCEA’s integrated national socio-economic model. The governed data, authoring, execution, and publication capabilities developed around it later evolved into the broader ONEMODEL Platform.
Move from a forecast to a system experiment.
Each scenario changes conditions inside the same governed model, so the consequences can propagate through behaviour, capacity, prices, institutions, and time.
What is public housing actually worth?
Compare investment and counterfactual pathways across housing, health, homelessness, employment, fiscal outcomes, and social value.
Who experiences an affordability shock—and how?
Follow heterogeneous impacts across renters, owners, age groups, incomes, regions, and household circumstances rather than relying on an average household.
What happens when infrastructure investment changes capacity?
Trace construction activity, economic propagation, household effects, fiscal beneficiaries, service capacity, and longer-term regional outcomes.
What the digital twin needs to represent.
The exact model can vary by project, but the value comes from keeping the important actors, state, constraints, and causal pathways inside one coherent simulation.
Actors and relationships
The model is built around individual agents and the relationships that make their state internally consistent.
- People → families → dwellings Individual circumstances connect to household structure and place through explicit relationships.
- Businesses ↔ workers Hiring, labour supply, wages, and production interact rather than being imposed as independent totals.
- Governments ↔ households/firms Taxes, transfers, spending, and public services create fiscal and behavioural feedback.
State and history
Scenarios start from an accepted historical state, preserving the path that produced current conditions.
- Demography Birth, death, migration, family evolution, and aging.
- Economic position Employment, income, business activity, housing, and affordability.
- Geography and capacity Places, infrastructure, service constraints, and local conditions.
Scenario levers
Policy and investment scenarios can alter conditions while preserving a common model and evidence chain.
- Housing and infrastructure Supply, renewal, capacity, timing, financing, and affordability.
- Labour and economic shocks Demand, productivity, industry change, labour-force transitions, and regional effects.
- Programs and fiscal policy Eligibility, transfers, taxes, public costs, and behavioural response.
Outputs and evidence
Results can combine conventional economic measures with distributional and human outcomes.
- Economic and fiscal GDP, employment, income, business activity, taxes, and public expenditures.
- Household and distributional Affordability, stability, housing outcomes, geography, and differences across populations.
- Health and social value Health-system use, homelessness, quality of life, and monetized social-value changes where supported by evidence.
Value is more than GDP.
CANCEA’s social-value work extends the evidence chain from economic outcomes into quality of life by connecting observed circumstances to empirically measured well-being.
Use the complexity only when it changes the answer.
ONEMODEL adds value when
- Effects propagate across households, firms, public systems, and markets.
- Distributional outcomes matter as much as aggregate totals.
- Housing, health, income, and well-being interact over long horizons.
- The counterfactual and path to the outcome matter to the decision.
A simpler model is enough when
- The question is descriptive rather than causal.
- A static aggregation or short-term forecast captures the decision adequately.
- The available evidence cannot support the desired behavioural or geographic resolution.
