Multiple birth numbers have remained relatively consistent in Australia over the past decade.
In 2019, according to the Australian Bureau of Statistics (latest report as of December 2019) there were 4,501 multiple births representing 1.5% of all births (305,832) in Australia. This comprised 4,446 pairs of twins and 55 sets of triplets and higher order multiples. One percent (or 55) of all multiple births are triplets and above.
Of all babies born in 2019, 9,002 of the 305,832 were from a multiple set (twins and above) or 3% of the total.
We are often asked how many multiples are there in Australia? The population of Australia is around 25.4 million, so we can estimate there are around 750,000 multiples (based on the estimate of 3% of the population is a multiple).
Interestingly, TRA has around 80,000 members, or around 11% of Australia's multiple-birth population is a TRA member. We thank the multiple-birth community for their wonderful support of our research and we welcome more to join us!
