U.S. and World Population Clock

The U.S. Population Clock hits 300 million in October 2006.

The U.S. and World Population Clock presents 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.

In June 2020, the Census Bureau gives the current population of the United States as over 329 million.^[1]

Calculation

The calculation used to estimate the approximate timely population is;

one birth per time T_W
- one death per time T_X
+ one international immigrant per time T_Y
= overall increase (one person per time T_Z).

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 minute and 8 seconds
