No one is gonna be born! According to this garbage BBC report of a even more vapid science paper, the on-going decline in the fertility rate will cause the world’s population by the end of the century to shrink by about a billion, with some countries losing half their populations.
Falling fertility rates mean nearly every country could have shrinking populations by the end of the century. And 23 nations – including Spain and Japan – are expected to see their populations halve by 2100. Countries will also age dramatically, with as many people turning 80 as there are being born.
What is going on? The fertility rate – the average number of children a woman gives birth to – is falling. If the number falls below approximately 2.1, then the size of the population starts to fall. In 1950, women were having an average of 4.7 children in their lifetime.
Researchers at the University of Washington’s Institute for Health Metrics and Evaluation showed the global fertility rate nearly halved to 2.4 in 2017 – and their study, published in the Lancet, projects it will fall below 1.7 by 2100. As a result, the researchers expect the number of people on the planet to peak at 9.7 billion around 2064, before falling down to 8.8 billion by the end of the century. [emphasis mine]
The key word in the quote is highlighted. It is also illustrated in the graph above, taken from the BBC article but annotated by me to indicate the time period in red where we have absolutely no data at all, and no one really knows anything. While the decline in fertility since the 1960 is well documented, caused by prosperity and greater choices for women worldwide, the projections beyond 2017 are not worth the money that the Bill & Melinda Gates Foundation paid for it. Those projections are based on models, and from what I can tell, those models are more opinion that anything. We really can’t predict what is going to happen, because the factors that have caused the fertility decline in the past half century might simply not apply in the next eighty years.
In fact, based on the completely unexpected disaster that occurred this year because of the Wuhan virus panic and the possible fundamental changes, for the worse, that this panic will likely bring to worldwide culture, the prosperity that fueled the fertility drop in the past half century might vanish, bringing about changes that make any projections into the future pure guesswork.
In fact, these models are probably as useless and as wrong as the models used to predict that millions would die from COVID-19 in the first year. In fact, this model is likely comparable to most scientific models that attempt to predict the future. You have a better shot at guessing what will happen by looking at tea leaves.
The sad thing is that the BBC is still reporting on a model like this as if it were real data, and therefore must happen. You’d think they’d learn.
