Modelled estimates

When a figure is calculated by a model rather than measured directly.

International organisations fill gaps where countries have no recent survey by using statistical models. The ILO modelled estimates and many UN health and population figures work this way.

They make it possible to compare almost every country for the same year, but they can differ from national survey results and are revised when new data arrive.

Pages for modelled measures say so in the definition and name the organisation that produced the estimate.
