How this brushing their teeth estimate works
Σ (region population × participation × local-hour probability)
The model applies 1.65 typical occasions per day to the eligible population, uses a typical 2-minute activity window, and distributes the result around local morning and evening routines across population-weighted time zones.
What the number means
Access and habits vary globally. 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.
