Population Growth

You might remember dire warnings some years ago about population growth, and the threat of overcrowding in the U.S.  So how fast, exactly, is our population growing?

United States Population Growth

The numbers might surprise you.  U.S. population growth from 2016-2017, 2017-2018, 2018-2019 and 2019-220 (so far) have been all below 1%: 0.64%, 0.62%, 0.60% and 0.59% respectively.  There are currently 331,002,651 people living in America, up from 325,084,756 in 2017.  The projected growth rate shows a continued decline down to near 0% over the next 50 years.

World Population Growth

But, of course the world’s population is growing at an unsustainable rate, right?  Actually, global population growth is higher than the U.S., but not by nearly as much as you might imagine.  In the years 2015 to 2020, the world population’s annual growth rate was 1.19%, 1.14%, 1.12%, 1.10%, 1.08% and 1.05%.  If you have nothing else to do, you can watch the number of people living on this planet go up in real time.  The website: https://www.worldometers.info/world-population/#:~:text=Population, shows that every second seems to bring about ten new people into the world.  In addition, it lists births and deaths on the calendar day that you log in.  It also shows a running tally of births (more than 116 million) and deaths (almost 50 million) this year around the world.


The site also lists the most populous nations. You already know numbers one (China: 1.44 billion; about 18.5% of the total) and two (India: 1.34 billion; 17.7% of the total).  The U.S. is a very distant third (4.2% of the world’s population), followed by Indonesia (274 million), Pakistan (222 million), Brazil (213 million), Nigeria (207 million), Bangladesh (165 million), Russia (146 million) and Mexico (129 million).  Finally, you can see the rankings that demographers expect in the year 2025.  They expect Nigeria to replace the U.S. as the third most populous nation on Earth, and that Ethiopia will come in at number 8, followed by the Democratic Republic of Congo at number 9.
