REVEALED! Australia’s most common and least common birthdays

The chart was released by the Australia Bureau of Statistics comparing the birthdays based on births between 2007 and 2016.

Baby making appears to be popular during the festive season – more people are off work and being merry – which is why September 17 is Australia’s most common birthday (9 months after Christmas).

Most common birthdays are:

• September 17
• April 8
• September 23
• September 24
• October 1
• February 12
• April 29
• March 4
• April 16
• March 5

Meanwhile, the least popular birthday is February 29th, which only comes around every 4 years.

Least common birthdays are:

• February 29
• December 25
• December 26
• January 1
• January 26
• April 25
• December 27
• December 28
• December 24
• December 13

It’s interesting to see that the least popular birthdays include quite a few public holidays – December 25 (Christmas Day), December 26 (Boxing Day), January 1 (New Year’s Day), January 26 (Australia Day) and April 25 (Anzac Day).

This may be because obstetricians may not induce women or schedule in c-sections on public holidays. Just over 32% of births in Australia were by c-section, research published in journal PLoS One found.

This may also explain why the majority of births take place in the week and not on the weekend.

“The problem is that there does not seem to be one explanation for understanding the different patterns that are seen between populations,” Associate Professor Edith Gray, head of demography at the Australian National University, tells ABC.

“What we know is that births peak in Australia in late September and early October. This is consistent with many other Western countries, including the USA, France, England and Wales, and New Zealand.

“Most researchers attribute this to ‘Christmas babies’ — that is, babies who are conceived during the Christmas holidays.”

September is the most popular month for babies to be born due to Christmas sex

People are doing more than just having a kiss under the mistletoe at Christmas!

To begin with, more people take annual leave in December, and more time off – or in bed- means more time to have sex.

In December people may find themselves at more parties and that often means more alcohol consumption, and it’s less likely that contraception is always used.

Or as the shops and pharmacies are shut for days at a time, it may be harder to access contraception or the morning after pill.

And it’s not just in Australia that conception is most popular in December, New Zealand, the U.S. and the U.K. also have the highest rates of birth in September also.
