Have you ever noticed a trend in when your friends have bubs? The Australian Bureau of Statistics (ABS) have some pretty revealing statistics suggesting why this happens!
And the winner is…
It seems that September 17 is the most common birthday in Australia, and you better watch out because babies born on that date are most likely conceived between December 21 to December 29.
April 8 is the second most common according to the ABS gang. Those babies are conceived between July 12 to July 20, leading us to believe that some people have their own genius ways of staying warm through the chilly months.
In a bit more detail:
- The September 17 date boasted 8862 births over a 10 year period.
- April 8 was lagging slightly behind, with 8,829 births.
- Next most popular was September 23. That date had 8816 births over the 10 years.
- September 24 and October 1 tied at fourth place, with 8813 tots.
- February 12 came 5th with 8810.
From here there’s a dramatic downward jump, as you can see from the graph below. It’s fair to say that the top 5 birthdays are separated by very narrow margins.
Not many bubs pop out on public holidays
The ABS Director of Demography, Beidar Cho, says these trends are not unique to our fair shores, with other countries mirroring the festive/freezing conception triggers, too.
“These trends are similar in New Zealand, England and Wales, and the United States. More babies are likely to be conceived around the Christmasand New Year holidays, [while] fewer babies are born on public holidays – possibly a result of doctors scheduling deliveries on non-public holidays,” Beidar elaborated.
Listen to Kinderling Conversation:
The data, gleaned from births registered between 2007 and 2016 really did show a remarkably big dip in births on Christmas Day, Anzac Day, New Year’s Day and Australia Day.
For those who love the underdog, the five least common birthdays were (in order of least popular to most popular at the bottom of the list) – February 29, December 25, December 26, January 1 and January 26.
Huge birth boom in Victoria
Births were UP in 2016, with 311,104 births registered in Australia, up from the 305,377 registered in 2015.
That said, some parents are apparently not registering their children’s births at all, particularly in NSW, where a new data processing system is apparently deterring mums and dads from getting their paperwork in.
Victoria experienced quite the baby boom in 2016 – up almost 13 percent – according to ABS data, but they worried that the lagging NSW birth registrations (by possibly sleep-deprived parents?!) might be skewing the result. It’s possible there are lots of babies who did not have their births registered before the data was examined. At this point the data shows that NSW births dropped by four percent between 2015 and 2016.
“Victoria recorded the largest increase (9,324 or 12.7 percent) in the number of births registered in 2016. Some of the increases were due to a catch-up in processing lags. New South Wales recorded a decrease of 3,996 births (4 percent),” the ABS tells us.
“The ABS is currently working with the NSW Registry of Births, Deaths and Marriages to investigate the decline in birth registrations, noting that processing issues can impact on counts,” the ABS said.
Fertility rates are constant
Across the country as a whole, fertility rates for women remained the same in 2016 as for 2015, with women having 1.79 babies each, which seems very tricky.
The fertility rate for Aboriginal and Torres Strait Islander mothers in 2016 was measured at 2.12 babies per woman.
The figures also show that income is linked to fertility choices. The further from the city a family is, the more babies they will have.
“Fertility rates between the centre of Australia’s two largest cities almost double once you reach parts of their outer fringes – from 0.9 babies per person in central Melbourne or Sydney to 2 in Casey or Blacktown,” The Age reports.
“The median age of mothers is 33 in North Sydney, Hornsby and Melbourne’s inner-east, but only 28 in western NSW and north-west Victoria.”
The stats also showed that Western Australia, South Australia, the Northern Territory and Queensland had the highest number of teenage mothers.
