How this sleeping estimate works
Σ (region population × participation × local-hour probability)
Population-weighted local time bands are combined with a typical eight-hour sleep window and broad participation assumptions.
What the number means
People likely to be asleep, with local night-time weighted across the world. 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.
