Indeed. underpopulation, at least if we define it as the lack of young people, is already being felt in many countries. Others are stemming the process through immigration.

But the practical end of mortality will make population jump to at the very least 13~15 billion, considering the original 9-11 billion projections by 2100, minus all these deaths. Maybe more if economic paradigms shift, etc. So we might be talking about 20 billion by 2100. There'll be nice cities all around the world at these numbers and available technologies...

Same could be said when Europe and Asia were in their 'high population growth phases'.

​

So much, Europe came with several theories and ideologies associating populational growth with poverty, due to misunderstanding of the rapid effects of advancing technologies in birthrates and goods availability overall.

​

Most of South Asia (India, Pakistan, Bangladesh) for example, albeit relatively poor (but not as poor as 30 years ago) is already seeing their fertility rates falling quickly, and economical development taking pace as wealth generation surpasses population increases.

Africa will take more time given higher rates, but will follow suit.Most modern cities barely existed as they are a mere 50 years ago.

China being the most staggering example, but with examples all across (mostly) East Asia and the Persian Gulf.

Even already stablished western nations saw that, depending on their urbanization model (less in USA where car centrism/suburbia is rampant, less in Europe where historical aesthetics is coded on law but more on Canadian and Australian cities)
