The US population clock hit a mathematically significant milestone on Tuesday - pi.
The US Census Bureau estimated that the clock struck 314,159,265 residents just after 2:29 p.m. That figure is pi (3.14159265) times 100 million.
Pi is a mathematical constant that is the ratio of a circle’s circumference to its diameter.
The US Census Bureau's top demographer celebrated with a pun.
“This is a once in many generations event...so go out and celebrate this American pi,” Howard Hogan said in a written statement.
