Population clocks provide current projections of estimated populations based on previously recorded data
- This information is typically gathered from regional and national census data and hence may not be highly accurate
Population clocks may also use established data to assume rates of change (e.g. growth rate and death rate)
- This allows the clocks to show dynamic changes to population data (although this information may not be very accurate)
While of questionable accuracy and validity, population clocks can be used as a tool for identifying changing demographics
- The human population is currently growing at a rate unprecedented in world history (what is the carrying capacity of man?)
