A horizon scan is a structured way to notice change early. We collect concrete signals — a product shipped, a policy passed, a behavior shifting — and cluster them into the trends and forecasts that show what cities should be preparing for.
Once a curator publishes a forecast built from clustered trends, a worked example walks through it here — signal → trend → forecast. Meanwhile, explore the raw signals in the graph below or submit one.
Signals are gathered from the crowd.
Curators cluster signals into trends — patterns with a direction and a timeframe.
Trends are woven into forecasts — a strategic, big-picture view of plausible futures for cities.
