All the examples of high population density per km² countries are losing population on long term (probably it can reverted in Netherlands and Belgium due mass immigration, but then it's another story). People from developed countries tend to have less children for some reason.
And these Africa countries population is growing fast on long term. One of the reasons may be due the mortality rates are decreasing. Africa is one of the most chaotic continents in the world, many epidemics and wars make the population grow slower, but it doesn't mean they tend to have less children.
Well, it's just an observation. You will find exceptions, but from a general perspective it really makes sense.
Yeah, I can agree with that but they are losing population only AFTER they have reached a developed status.
And people in developed countries tend to do that because they want to still have some time off while raising kids (impossible with
and because they are planning ahead, you won't be able on the average wage to sustain 8 kids at the level you can do with 2.
In poor countries...those are stupid ideas. You need to keep
producing them to help you at work, screw education, screw other needs, all that is important is manpower. No wonder in many countries families is really disappointed when they get a daughter and not a son.
The developed countries invented the technology the whole world has access nowadays, even the developing countries. It's acceptable they needed manpower a century or centuries ago, when these technologies weren't disponible yet. Once new technologies came in, they were shared with another countries too (machinery, vehicles, tools, internet, cellphones, computers, transgenic food, etc...). The whole world was benefited, including the poor countries. So why would they still need manpower like in the old times?
Also note that assistencialism nowadays is much stronger than times ago.
If they had followed the developed countries trend, they would be more wealthy nowadays. As you said:
"you won't be able on the average wage to sustain 8 kids at the level you can do with 2." The same premise worths for developed and developing countries. This mass production developing countries keep doing isn't necessary anymore on the modern world... But they keep doing this.
Besides, density is also heavy influenced by a lot of other factors.
If we look at Japan and New Zealand,330 vs 15 per km2, both islands, both developed countries yet....
Even if we talk about African Countries, Nigeria is at 200 while Niger at 15.
And there are huge differences even in the US, for example, Nebraska and California.
As you said, countries start losing population AFTER they reach a developed status, that is Japan's case. New Zealand was established by British people, another situation; There are countries which part of their territory is uninhabitable, and it can also happen in regions inside a same country: Like drought areas, protected environmental areas... Instead of looking the general density of a country, to look the cities density would be wiser. They are overpopulated, precarious and keep increasing without planning, that is a characteristic of developing countries.
