One of the things China and the USA have in common is the fact they are both about the
same size.
In terms of land area the U.S. is 3,532,000 square miles, or 9,148,000 square kilometers
not including overseas territories.
China is 3,601,000 square miles, or 9,325,000 square kilometers, and no, that doesn’t
include Taiwan or Hong Kong.
Today we will attempt to fit the Chinese population inside of the USA and see what happens, and
the results might not be what you think.
First, we should learn a bit about the populations of each country.
Populations are of course always changing, but the website Worldometers tries to give
an accurate number of people living in all nations.
As we write this, the website tells us that the population of China is 1,419,803,000.
We don’t need to tell you that it keeps going up and up.
The USA has a much smaller but still large population of 328,972,000.
So, for every one person living in the USA, there’s about four point six people living
in China.
Given that massive population, does that make China the most densely populated country in
the world?
No, not by a long shot, it’s the very smallest countries that have the densest populations.
China has a population density of roughly 375 per square mile (145 per square kilometer),
while in 2014 Hong Kong, which is part of China but still an autonomous territory, had
a population density of a whopping 6,690 people per square kilometer!
Even the UK is much more densely populated than China, which is only the 59th most densely
populated country in the world.
The USA is actually one of the most spacious countries out there and comes in at 146th
on the list.
As we said, China and the USA are very close in geographic land mass.
You could almost fit one snugly into the other if you played around with the shapes a little
bit.
But in terms of how spacious a place feels, it really means how packed the populated areas
are.
A remote mountain area in China is as crowded as a remote mountain area in the USA.
So, which country has the busiest cities in terms of finding space?
According to the most recent estimates available, in 2018 New York city was the most populated
city in the USA with 8,399,000 living there.
Los Angeles is way behind at 3,990.000.
For New York, there is a population density of 28,317 people per square mile.
That makes it the most cramped city in the USA.
LA only has 8,484 people per square mile.
Shanghai has a much larger population of 26,316,000, but is it more cramped than New York city?
Actually, it isn’t.
Shanghai has a population density of only around 11,000 people per square mile, so New
Yorkers would actually feel like they had more space if they were living in Shanghai,
while Shanghai residents might consider New York City to be a bit cramped for their tastes.
Most sources consider Manila in the Philippines to be the world’s most densely populated
city with 107,561 people for every square mile, while others say it’s actually Dhaka,
Bangladesh.
Shanghai by the way is 2,448 square miles in area, or 6,341 square kilometers.
New York city is much smaller at only 468.48 square miles or 1,213 square kilometers.
These are each country’s biggest cities in terms of population, but there is a long
list of Chinese cities with populations bigger than New York.
We tell you this of course because if the Chinese population was suddenly moved over
to the United States then they would most likely have to populate the cities.
If we dropped, say, the population of Beijing, about 22 million and 3,400 people per square
mile, next to Mount Katahdin in northern Maine we’d have a problem as there is no infrastructure,
so when we talk about upping the U.S. population we are focusing on the places people can live.
As we said, China’s huge population means the country has a much greater number of large
population cities.
When you look at lists of world’s largest cities by land area, whether urban area or
metropolitan area, Chinese cities make up a lot of the lists, as do Indian cities.
In fact, in the top 50 largest cities we only see New York city on the list from the USA,
whereas China makes the top 50 a staggering 23 times.
What this means of course is that if the USA had the same population as China and city
dwellers remained city dwellers then many cities in the USA would be extremely crowded
places.
China can deal with that many people, the U.S would struggle.
OK, so what would the consequences be of this population explosion?
Well, if it happened at once, say by magic, all hell would break loose.
If the population was the same ratio of children to adults there’d be too many children to
feed and too many adults for jobs, not to mention a lot of houses with too few beds.
Could this happen?
Obviously not, but if it ever could it would have to mean something happened which resulted
in a huge migration to the USA.
We might have to invoke alien attack here because we don’t feel this could be anything
but science fiction.
According to the IMF’s World Economic Outlook Database the nominal GDP for the USA in 2018
was the highest in the world at $19.39 trillion.
China’s was $12.01 trillion.
If we look at this in very simplistic terms it should mean there is enough cash in the
USA to feed a population that was the same as China’s, although massive changes in
the allocation of funds, new taxes, and changes to monetary policy would have to happen.
Still, there is little doubt this new population could eat, it would just mean some growing
pains for a while.
Let’s say things were straightened relatively quickly thanks to American ingenuity, there
would still be too many people filling cities that once had far fewer people.
There would have to be drastic expansion, and that would mean spending an incredible
amount of money on infrastructure.
But given the USA’s incredibly high defense budget which could be slashed and so many
billionaires ready to taxed, we think that this could be done without a total catastrophe.
Things would be tough at first, and no doubt a lot of the population would be up in arms,
but once they knew they had no choice they would deal with it.
In our sci-fi hypothetical crowded America, we’re assuming people would, for the most
part, be willing to collaborate to build a bigger, better America.
One of the very real problems with this influx of new folks would be the degradation of natural
spaces and depletion of resources.
As Jared Diamond points out in his very real book, Collapse, parts of the USA are already
suffering from the over consumption of natural resources and the negative effect this is
causing on the environment.
More people means more pollution.
It means more polluting industries, more cars, more houses, more degradation of farmland.
There would no doubt be some scarcity.
Fish depleted rivers will need to be filled.
People might even have to learn how to be more self-sustainable.
People would also have to put their trust in the government and a whole group of round
table experts would have to get busy coming up with ways to accommodate these new folks
without taking the USA to the brink of collapse.
Diamond points out that societies have completely disappeared in the past because there just
wasn’t enough resources to accommodate a growing number of people.
But the point he makes is that collapse in hindsight was probably always avoidable had
those societies been savvier about over-consumption and the sustainability of natural resources.
Some societies chopped down all their forests in part so they could build monuments to show
how strong they were.
Bad move.
In the new U.S. people would care less about what they had; there would be less conspicuous
consumption and more people would embrace a kind of communitarian life.
No, that doesn’t mean communism, it means working together for the greater good.
There would have to be a profound change in habits and some great innovations.
Let’s just say because of these A-teams of innovators and a public willing to make
profound lifestyle changes, the plan came together.
Would a more crowded America sink into poverty?
We think the answer is no, not at all.
More people means more brains, more innovation, and you work with what you’ve got.
Sure, parts of America that have been historical under populated would have more people, but
those people could and would be useful.
We could call this sci-fi situation “The Great Expansion”, and it wouldn’t be that
different from the expansion America saw in the 19th century when wagon trains, many full
of immigrants, went west to stake claims in new territory.
It could be a catalyst that made people think more about the environment and act in a way
that aligns with human progress and happiness.
America would deal with the Great Expansion, but modern Americans like their hardworking
forefathers would learn to find greatness as the country builds a new frontier.
Or do you disagree?
Would the overpopulation cause groups becoming more insular and lead to war, disease, and
famine?
