Social Sustainability Index Simulator

Social sustainability is usually described in words — inclusion, equity, health, education, community participation — but rarely shown as a mechanism. This simulator turns four of its core indicators into a coupled dynamical system: education, healthcare, housing affordability and civic participation each evolve toward a policy-investment target while feeding back into one another, exactly the reinforcing loops that social-sustainability research documents between these domains. A grid of 168 households, rendered as an instanced 3D block city, is colored by individual wellbeing drawn around the community mean at a spread you control, so you can watch inequality — measured live as a Gini coefficient — widen or narrow as policy changes ripple through the system. A shock button drops housing affordability suddenly, letting you see how far the community's resilience buffers a downturn before the composite Social Sustainability Index recovers.
