U.S. and World Population Clock gives an estimate of the population for the United States, and the World. On April 26,2017, at 13:41:31 UTC, an estimated 324,935,042 people lived in the United States (50 states, and District of Columbia.) The World population is 7,386,876,180.

Coordinated Universal Time (UTC) is the time standard used here. UTC is similar to Greenwich Mean Time. “The reference line or starting point, the Prime Meridian, was determined to be the transit circle at the Royal Observatory in Greenwich, London.” UTC is four hours ahead of Eastern Daylight Time. The population reading above was at 9:41:31 EDT.

The question for today is: When will the US population hit 333,333,333? Here are some hints: “Components of Population Change: One birth every 8 seconds, One death every 11 seconds, One international migrant (net) every 32 seconds, Net gain of one person every 15 seconds.”

The target population, 333,333,333, is 8,398,291 more than the current population of 324,935,042. Assuming a net gain of 5,760 per day, (one every 15 seconds, 4 per minute, 1440 minutes a day) we will hit the target number in 1458 days. 5,760×1,458=8,398,080, 211 less than the target.

Friday, April 23, 2021 is 1,458 days in the future. 211/4 is 52.75. This gives us a time of 14:34:16 UTC, or 10:34:16 AM EDT. At this time, the population of the United States will be 333,333,333.

Pictures today are from The Library of Congress. Esther Bubley took the pictures in September, 1943. “A Greyhound bus trip from Louisville, Kentucky, to Memphis, Tennessee, and the terminals.”
