Population Clock

Posted 2023-11-20 09:44:36

 

How in the world does this clock conclude that there is a net gain in the United States of one person every 29 seconds? Students use fraction operations and least common multiple to check the math. 

Have a little care about younger children when using this activity. The population clock deals with the rate of deaths in the United States. 

Updated September 2026 with the current Census rates.
