How our numbers work

  1. 1

    Collect dated sources

    Every market figure traces to a source record with an organisation and a date.

  2. 2

    Preserve scope

    We keep each source's exact meaning — a range stays a range; we never average conflicting scopes.

  3. 3

    Show assumptions

    Calculators use your inputs and a visible formula, so you can see exactly what drives the result.
