How Housing Market Insights Chooses and Checks Its Sources
Tutorial 18 of 30 · 50 s
Before you quote a market figure to a client you want to know where it came from. The Methodology and sources page of Housing Market Insights explains it in plain English. This tutorial walks through the page: where the figures come from, how a source is approved automatically with a trust score, what probation means, and the confirmation rule — a figure is published when at least two independent sources agree, or when it comes from the official publisher of that statistic. It then covers whose figures may be shown, how often figures update, why only aggregated statistics are published, and where to report a problem.
In this tutorial you will learn
- Which organisations the figures come from
- How a source is approved, put on probation or dropped
- The rule: two independent sources, or the official publisher
- Why a figure can be held back
- How to report a figure you think is wrong
Follow along: the steps
- Open Methodology and sources from the top menu.
- Every figure comes from the organisation that published it.
- Statistics offices, central banks and international bodies.
- Each source gets a trust score; approval is automatic.
- In between, a source goes on probation: collected, never shown.
- A figure needs two independent sources, or the official publisher.
- Figures are never averaged, and odd jumps are held back.
- Figures are shown only when the source allows reuse, with attribution.
- Each figure shows the period it covers and when it was released.
- Only aggregated statistics — never a property or a person.
