In a snark before a totally unrelated item, Oz Strewth columnist James Jeffrey writes
ACCORDING to the UN (there’s a statement that doesn’t exactly carry a a lot of weight, but let’s push on), the world’s human population should pass the 10 billion mark some time around 2040.
As you’d expect of any factual claim made in the Oz, he’s wrong. The UN medium projection is for a population around 9.2 billion in 2050. Even on the high projection, 10 billion isn’t reached until about 2045.
