The Population Clock is the United States Census Bureau's continuously active approximations of both the population of the United States and the world's total population. The population totals are based on the latest census information and national population estimates, which are used in the algorithms that run the two clocks.
The calculation used to estimate the approximate timely population is
one birth per time TW
- one death per time TX
+ one international immigrant per time TY
= overall increase (one person per time TZ).
For example,
one birth every 1 minute and 56 seconds
- one death every 3 minutes and 59 seconds
+ one international migrant every 3 minutes and 11 seconds
= one person every 1 minutes and 44 seconds
