Every city in Fab City makes one promise. The Index shows who's keeping it.
By 2054, produce (almost) everything it consumes. This is how you see which cities are actually moving, and which are standing still.
A metabolism, not a snapshot.
Every city takes things in and puts things out. The old economy runs one way: products in, trash out. You buy what you need from far away and throw it away nearby. We call that PITO.
A Fab City runs the other way. It senses what's happening on the ground, shares designs and know-how openly, and makes more of what it needs close to home. We call that DIDO.
The Index measures both, then adds the part no one else scores: how fast a city turns what it learns into action. A reading nobody acts on changes nothing. We call that speed ρ. The full method, gaps and all, is on the methodology page.
Read it. Feed it. Build it.
Observe
You want to read the instrument: the argument, the cities, the global picture. Most people start here.
Open the atlasMaintain data
You run a partner lab or lead a city's data. You connect the sources that fill the Index.
Open the workbenchRun a campaign
Your community needs to create data no platform holds: sensing, surveys, the things people actually care about.
See Making SenseOne tool, four regions, honest about what's real.
Barcelona is our first real attempt at live data. Boston, Santiago and Bali run in the same tool with placeholder numbers, clearly labelled. The structure is real. The data is still being filled in.
The instrument, in four parts.
The Matrix
The twenty parts of city life the Index reads: four pillars across five scales, neighbourhood to bioregion.
