Methodology

How United States data is produced: how visits are detected, how observations are scaled to population, and how privacy is enforced. Methodology follows the underlying signal, so what applies in United States is determined by its supply.

United States is served by GPS. Methodology for other signals does not apply here and is not shown.

Foundations

Per-model methodology

The pages above cover the foundations shared across United States. Model-specific facts, such as production lag and data flags, are shown on each dataset's page.
