Our media is silent on this, so I crunched the numbers myself on what the population of my country (Canada) will be in a couple hundred years based on current fertility rates.
The rate here runs about 1.5. It had been dropping for decades but it’s actually risen slightly higher to between 1.5 and 1.6 lately because immigrants have raised the average.
For my calculations I will assume it stabilized at 1.5, even though it’s now lower and still dropping for those living the western lifestyle. en.wikipedia.org/wiki/List_of_countries_and_territories_by_fertility_rate
Note, we’d need a fertility rate of 2.0, and then some, to maintain population. This would replace both parents and then factor-in mortality rates.
I’ll assume a zero mortality rate, and that everyone lives to eighty years old. (not to offend you old-timers, it just makes my calcs simpler.)
Assume 50% born female (it’s actually lower but again makes calcs simpler )
I’ll use a “generation” as 20 years.
2007 national population estimate is about 33 million.
2007 estimate women aged between 20-40 4.516M
1st generation progeny 4.516 X 1.5 = 6.77M
2nd ) 6.77M X .75 (that’s 1.5/2) = 5.01M
3) 5.01M X.75 = 3.81M
4) 3.81M X.75 = 2.86M
5) 2.86M X.75 = 2.14M
6) 2.14M X.75=1.61M
7)1.61M X.75=1.21M
8)1.21M X.75=.904M
9).904M X.75=.678 M
10).678M X.75=.508M
Then to arrive at the population after ten generations of twenty years (~200 yrs) I’ll sum the final 4 generations to arrive at about 3.3 million people - less than one tenth of today’s population.
The above excludes population increase from immigrants; I’m extremely confident that big business and big government will cooperate to ensure a net yearly population increase in order to grow their economy. (see fertility chart link to see where they’ll come from, and also see world populations by persons/square mile)
If anyone sees anything seriously flawed with the calcs could you let me know. I know I could have simply used the compound interest formula but longhand shows it more plainly.
I’ll leave it to you to deduce the social implications of this. I’m just running the numbers by applying the facts. However I could say with confidence that North America will be unrecognizable in just a few generations and that would be a conservative assertion.
