How this on a phone call estimate works
Σ (region population × participation × local-hour probability)
The model applies 55% broad participation to the eligible population, uses a typical 8-minute activity window, and distributes the result around local daytime hours across population-weighted time zones.
What the number means
Voice calls across mobile and fixed lines. Daily routines vary with age, work, culture, access and household patterns. The number is a broad modelled estimate, not direct tracking of individuals.
This estimate is for curiosity and perspective. Activities can overlap, and the totals should not be added together as if every category were exclusive.
Baseline sources
These sources anchor the normal model. Activity-specific participation and duration remain clearly labelled modelling assumptions.
Status: Activity-specific source review in progress. Last reviewed: August 2026.
