The ongoing COVID-19 pandemic is reducing life expectancy, decreasing birth rates and slowing down immigration. These changes may produce concerning trends in populations globally.
It took just 5,000 years for large and well-organised groups of people to populate all corners of the continent.
The 'exodus' from capital cities amounts to 0.06% of their populations – similar to recent years – and people are still moving to the cities. What's missing is growth driven by international migrants.
If we want a liveable future for our grandchildren is it ethical to reduce the number of people being born into that world?
Humanity is destroying Earth’s ability to support complex life. But coming to grips with the magnitude of the problem is hard, even for experts.
Researchers say around 70% of the US needs to get the coronavirus vaccine to stop the pandemic. But questions around the vaccines and regional differences add some uncertainty to that estimate.
Planning for Nigeria's next census scheduled for 2021 must address critical issues.
Until now, the US has been the most popular destination for potential migrants, and Australia around fifth.
With 70 percent of its people under 30 years, Nigeria needs to harness the strength in its youthful population.

Australia lacks a coherent national approach to planning where settlement and growth happens. It's time to take stock of our cities and regions and work together to improve outcomes across the nation.
Under a severe scenario, Australia’s population will be 4% smaller than if the pandemic hadn't occurred.
Why there's no need to panic over warning of 'jaw-dropping' fertility decline.
Despite the hype about a "coronial" baby boom, the pandemic is likely to see many Australians delay or not have children at all.
Why one city suffers significantly more deaths than another isn't always obvious. A simple experiment shows how failing to consider certain factors can point policy makers in the wrong direction.
Neighborhood characteristics like pollution from busy roads, widespread public transit use and lack of community-based health care are putting certain communities at greater risk from COVID-19.
It is easy for people in the industrialised world to blame population growth elsewhere for environmental damage. But increased consumption is just as important – if more confronting.
Labor's immigration spokesperson Kristina Keneally says immigration has "hurt many Australian workers". The evidence suggests it hasn't.
