The Melbourne Age has a piece about the record number of babies born in Australia in 2010.
One interesting fact:
Of the new parents, 66 per cent had made the trip down the aisle or had registered a marriage before the birth of their child.
The relevant statistic in New Zealand would be 51 percent (2009), a big difference probably largely accounted for by the low rate of marriage among Maori.
On the lighter side the article also gives New Zealand a mention:
Across the Tasman, New Zealand is expected to experience a mini-baby boom of its own sometime next July.
The last time the All Blacks won the Rugby World Cup in 1987, there was a surge in births nine months later that statisticians explained away as a country in celebration - and copulation.
And typically I wonder how many of these predicted births will be to people able to support a child?
