Given the deluge of media coverage on the US border situation in recent months, it's worth repeating that many non-USA parts of the West are projected to undergo population growth of around 40% in urban areas over the next 20 years, with some places exceeding this figure significantly.

What's even more alarming is the concentration of this growth in established major centres, where there are MANY instances of urban localities more than doubling in population in under 20 years.

I have my doubts about whether some of these projection will actually come about, because there is simply not enough infrastructure in the pipeline to make it happen, but in the short term many national level governments are actually using these "projections" as a justification for relaxing their immigration policies, meaning it would be more honest to call them "targets".

It's a malicious piece of circular reasoning they are doing. Out of one side of their mouth, they state that the projections predict exponential growth, therefore we must spend, spend, spend on more infrastructure. Then from the other side of their mouth, they say the infrastructure and the economy needs more migrants to function and policy must be relaxed if the "projections" are going to be met.
