Typical 24 Hours
The interactive 24-hour curve loads with the live model.
This curve shows a typical modelled day, not historical observations.
How this sending messages estimate works
Σ (region population × participation × local-hour probability)
The model applies 7 typical occasions per day to the eligible population, uses a typical 1.2-minute activity window, and distributes the result around local daytime and evening hours across population-weighted time zones.
What the number means
Short person-to-person digital messages. 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.
What changes this estimate?
Baseline sources
Country populations and civil local clocks are source-based. Activity frequency, participation, duration and the hourly shape remain experimental assumptions; these inputs have not been measured worldwide.
- United Nations — World Population Prospects 2024
- UN WPP 2024, original demographic workbook (GEN/F01/Rev.1)
- IANA Time Zone Database — civil time zones
Status: Activity-specific source review in progress. Population and clock review: 8 September 2026. Activity-specific limitations are stated above.
