One is that the world's population is increasing rapidly; and the other is that fertility is on the decline. There are many interacting factors underlining the fall in the fertility rate. The most obvious are the modern fertility control measures and the related changing patterns of family formation.
Declining fertility rates are a consequence of a confluence of many related factors, including (but not limited to): Better access to contraception. Improving opportunities for women, outside of childbearing. Robust healthcare that lowers mortality rates of children.
In 2020-21, the fertility rate was 1.66 babies per woman, similar to the rate recorded in 2018-19. In 2019-20, the rate had fallen to 1.61 babies per woman. According to the report, the data suggests people “adapted to the uncertainty of the pandemic and quickly caught-up on delayed childbearing plans”.
Since 1976, Australia's total fertility rate has been below replacement level (about 2.1 births per woman). Replacement level is the level at which a population is replaced from one generation to the next without immigration.
The problem with low fertility is that it reduces population size not at all ages but only among the young. Low fertility produces an age structure that creates a momentum for future population decline, a situation that must be stopped at some point if the population is to be demographically sustainable.
South Korea has the world's lowest fertility rate, a struggle with lessons for us all. A woman holding her daughter looks at a view of Seoul in 2019. The fertility rate in South Korea, which has the world's lowest rate, hit 0.78 in February.
South Korea has the lowest fertility rate globally at 0.9 children per woman, closely followed by Puerto Rico at 1.0 and a trio of Malta, Singapore, and the Chinese Special Administrative Region Hong Kong all at 1.1 children per woman.
It's no secret that Australians are having fewer children. The latest ABS statistics reveal our fertility rate was 1.7 – well below the so-called replacement rate needed to keep the population growing. The last time our fertility rate was this low we started literally paying people to have babies.
About one in six Australian couples experience fertility difficulties. There are many reasons for this, some relating to the male partner, some to the female partner, and sometimes both. For many people, there is no medical explanation as to why they can't conceive. This is referred to as unexplained infertility.
Having Babies After 35 Is Safe
And while it's true that conceiving after 35 comes with an increased risk of complications—like preeclampsia, gestational diabetes, chromosomal abnormalities, and even miscarriage or stillbirth—many people go on to deliver healthy babies.
Australia's population density is low because most of the country's interior is desert (also known as the outback) and presents extremely difficult living conditions.

But during the Great Recession, from 2007-2009, birth rates declined sharply – and they've kept falling. In 2007, average birth rates were right around 2 children per woman. By 2021, levels had dropped more than 20%, close to the lowest level in a century. Why?
According to the report, which was carried out by researchers at UNSW, there were 88,929 IVF cycles started in 2019 in both countries (81,049 in Australia and 7880 in New Zealand), leading to 16,310 babies born through the treatment.
In 2022, Levine and his collaborators published a review of global trends in sperm count. It showed that sperm counts fell on average by 1.2% per year between 1973 to 2018, from 104 to 49 million/ml. From the year 2000, this rate of decline accelerated to more than 2.6% per year.
Women can reproduce for about half of their lifetime and can only give birth about once every year or so. So it makes sense that women can only have a fraction as many children as men. One study estimated a woman can have around 15 pregnancies in a lifetime.
This decline is in particular a result of increased childlessness, higher age at first birth, and a smaller proportion of two-child mothers having a third child.
The current fertility rate for Australia in 2023 is 1.784 births per woman, a 0.56% decline from 2022. The fertility rate for Australia in 2022 was 1.794 births per woman, a 0.5% decline from 2021. The fertility rate for Australia in 2021 was 1.803 births per woman, a 0.55% decline from 2020.
More and more people in Australia are turning to IVF to have a baby. The latest data from Victoria show that the number of women having IVF increased by 20% in the past year and the number of treatment cycles increased by 27%. So, more women are having more cycles.
Key points. Oft-cited "nationally representative polls" suggest men want children more than women in the United States.
Singapore tops the list, with a childless rate of 23%, followed by Austria, the U.K., Finland, Bahrain, and Canada. Liberia and Congo report childlessness rates below 2%, although the UN states that childlessness typically doesn't dip below 3%, so these values should be viewed cautiously.

Retrieved June 1, 2023, from www.marchofdimes.org/peristats. In the United States, the highest fertility rates (per 1,000 women ages 15-44) during 2018-2020 (average) were to Hispanic women (64.8), followed by blacks (62.6), American Indian/Alaska Natives (60.8), Asian/Pacific Islanders (55.6) and Whites (55.3).
Based on that data, the researchers estimate that lifetime prevalence of infertility – representing the proportion of people who have ever experienced infertility in their reproductive life – was 17.5% in 2022.
