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.
The current population of the United States is 328,351,601.

Calculation
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).
