TOP 20 Countries with the most population in 2100! NOW VS YEAR 2100!

It looks like Mexico will be growing at a very slow rate, but still growing...hopefully during this time it will be able to provide a better quality of life for its citizens, primarily by targeting corruption (which involves security), followed by investments in education. Long road ahead....

Also, looking at current immigration patterns, the highest percentage growth of any immigrant groups is already from Africa...so if the demographic trends continue in their home countries, I definitely see Africans becoming the next 'Chinese'. These immigrants also do very well in the countries they immigrate to, especially Nigerians who are on average some of the most educated and highest earning - even more so than other well educated/high earning groups like the Chinese, Indians and Jews - within their newly adapted country. I'm not sure how much of this translates into a net negative for Africa (brain drain) or net positive (growing remittance).

The population increase in the USA would be due to immigrants INTO this country. The population of those that have lived in USA for generations would decrease dramatically... maybe about 20%-30%? Reason being is because back then in the 1950s, it was common for families to have 3-6 kids or more.

Now it's usually 1 or 2 kids. The few Americans having more kids are the really wealthy, religious Americans that do not believe in BC, or the poor that try to "milk" the system to get more benefits. Millennials today are half of the Baby Boomer population, when the Boomers retire they are tasking about half of their "population" to work hard and pay for their Social Security and taxes/pensions.

Generation Z as of today, is roughly the same population as the Millennials. Also keep in mind the trend for women to start families later, to put careers first and then families, to freeze their eggs, etc. If there were NO immigration in the USA in 2100, then America's population would've fallen 30%. That increase that they source counts for immigration though

Unless food can be easily 3d printed the population will not grow that high in Africa.
