Methodology and Data
Data Sources and Model Assumptions
humanitytracker.com deliberately uses simple, transparent estimates. The site is designed to make relationships understandable, not to replace official demographic data.
Core Dashboard Values
- Current world population: about 8.1 billion people
- People who have ever lived: about 117 billion people
- Births per day: about 360,000
- Deaths per day: about 170,000
- Net growth per day: about 190,000
Historical Reference Points
The historical development is interpolated from rough reference points. Between those points, the dashboard uses linear interpolation.
| Year | World population | People ever born until then |
|---|---|---|
| 1 | about 300M | about 45B |
| 1000 | about 310M | about 50B |
| 1500 | about 500M | about 56B |
| 1800 | about 1.0B | about 65B |
| 1900 | about 1.65B | about 82B |
| 1950 | about 2.5B | about 95B |
| 2000 | about 6.1B | about 110B |
| 2026 | about 8.1B | about 117B |
Continents and Countries
Continent and country figures are rounded, plausible sample values. They are used to visualize relative orders of magnitude and may differ from current official or scientific datasets.
Why Estimates?
Historical population figures and the total number of people ever born cannot be counted exactly. Values are therefore clearly marked as approximations.
