There are numerous extremely popular videos on YouTube about China’s imminent demographic collapse. People like Peter Zeihan have popularized the claim that China will lose half its population by year 2050. Is that possible or probable? Simple demographic math will debunk this sensational claim. Let’s take a look.
Who will be dead by 2050?
So, how many Chinese will be dead by 2050 … i.e., in the next 28 years? Well, China’s life expectancy is now 78 years. Let’s assume that it stays the same (although it will likely go up).
In 2050: Who will be 78 years of age or older?
Answer: That will be people who are now (in year 2022) 50 years or older.
Question: How many people are now 50 or older? The answer comes from the population pyramid — about 33% of the population.
So, right away, we see the problem with the doom-and-gloom predictions. But the anti-China people also ignore something else: BIRTHS.
How many babies will be born in the next 28 years?
It’s hard to tell how many babies Chinese will have every year over the next three decades. Here’s the data for births per year over the last decade.
COVID obviously had a big impact, and perhaps the rate will go up after next year. However, let’s be conservative and assume that there will be on the average 10 million births per year.
That means 280 million new babies by year 2050.
Net Population in 2050
So, here’s the simple math.
Deaths = 460 million
Births = 280 million
Net population change: Decrease by 180 million. (460-280 = 180).
Population in 2050 = 1.4 billion minus 180 million = 1.2 billion!
But China Lies!
Of course, Peter Zeihan and others also claim that China lies about its population, and the real number is 100 million smaller. Okay, let’s say that it’s true (although these conspiracy theorists don’t have any solid proof for this claim).
So, China’s population in 2050 can be as low as 1.1 billion (1.2 billion minus 100 million).
Less than 10% decrease!
Assuming the worst case scenario, China’s population will decrease as follows:
2022: 1.3 billion
2050: 1.1 billion
That’s a decrease of 8.5%! Far cry from the wild and irrational claim of 50% collapse.
Conclusion
In terms on median age (38) and fertility rate (1.3), China is no worse than developed nations, some of whom like Germany, Japan and South Korea are actually much worse off.
Thanks to increased deployment of automation, robots and AI in the future, many countries will be better off with fewer people.
China has been #1 in sales of industrial robots for several years, now accounting for 40-50% of the global market:

Also, China can implement new policies to encourage more babies — like providing subsidized or free housing and childcare for young couples. At some point, China can also bring in immigrants from neighboring countries to do labor-intensive factory jobs.
I agree that 50% population implosion seems incredibly high. However, I'm not sure where you got your 33% number for those 50+ years old. I went to the same website you pulled the data and downloaded the CSV file. Taking the sum of all the people 50+, the number is 662.5 billion (740 billion under 49 years). That's 47%. Using your birthrate, which seems quite optimistic since the birth rate was dropping before Covid, the population in 2050 would be (662.5-280) 382.5 million fewer people. Then take the 100 million the author claims as an overcount, and we're left with 482.5 million fewer Chinese. That's not 50% of the current population, more like 33%, but losing 1/3 of a population over 28 years does seem like a collapse. I'm sure the calculation is much more complex than this simple math though.
