This page joins one observed leading indicator, the dwellings a council is completing, to one slow system, primary school provision, through assumptions you can see and move. It ends in a statement about timing, which public data can support, and never in a statement about need, which it cannot.

The chain

Assumptions you can move

These are assumptions, not evidence. Each one is shown with where its default comes from. The scenario below is arithmetic on the observed and projected figures and on these values; move a slider and the scenario moves with it.

Scenario

Timing

Which assumption the answer rests on

Each assumption moved on its own to the low and high end of a stated band, the others held. The largest swing is the number most worth checking before quoting anything.
