Happy "ask your mates at other universities to say something nice about your own university and vice versa in order to prop up the giant farce that is the completely unnecessary but highly profitable university "rankings" industry"-day, for all the simps that celebrate it.

A quokka and Rottnest Island beach yesterday.

I suspect this is sensationalist nonsense. It is a projection not a forecast apparently based on linear extrapolation with no mention of effect of immigration (hence children, grandchildren etc etc of immigrants) perpetuating some level of population floor.

Which TFRs would prevent population decrease in 2024 if
deaths and net migration
are as per 2024 US census bureau estimates?

China 1.27 (vs 1.23 for 2024)
Japan 2.27 (vs 1.40)
South Korea 0.81 (vs 0.68)
Italy 1.40 (vs 1.26)

The population of New South Wales is projected to increase from 8.1 million in 2021 to
10.1 million in 2041, despite
a low assumed fertility rate.

The growth may be seen as the product of fertility being above the MIGRATION-ADJUSTED replacement level.

Yes I remember examples from when my kids were in day care. There have also been increases in childlessness (although some of this is just more overseas students, working holidaymakers etc getting counted in the population).

The evidence gathered from 127 peer reviewed papers shows that climate change impacts increase economic inequalities and disproportionately affect the poor, both globally and within countries on all continents

So how should we celebrate 20 million?
Cake and fizzy drinks anyone?

Australia's once universalist family payments system has gradually wound down to a more residualist one through changes to indexation and eligibility.

From ~100% coverage in the 1970s to below 50% coverage in the 2020s 😬

Slightly more than half of the Hungarian population (56%) live to reach Hungary's life expectancy age of 77, the lowest share in Europe. Countries with higher life expectancy generally exhibit lower inequality in lifespan.
