During the first year of the pandemic the news was particularly grim: Australian Bureau of Statistics (ABS) data<span>¹</span> revealed that 3 00 000 babies were born for the first time since 2007, and the estimated total fertility rate (TFR—the total number of children born to each woman if she were to live to the end of her child-bearing years) had fallen to 1.58, the lowest in Australia's history and representing a fall of 56% from the peak in 1961 (when the TFR reached 3.55).</p><p>A slight rebound in the number of babies born was observed in 2021—perhaps the result of people delaying pregnancy rather than abandoning the idea altogether—the situation again appeared grim with the release of the 2022 birth statistics.

Indeed, Australia's birth rate had been in established decline well before the pandemic (Fig. 1). Putting this in a global context, too, the fall in fertility rates seen in Australia is hardly unique: across the globe birth rates and resulting TFR estimates have been in decline since the 1960s (Fig. 2).</p><p>Population is influenced by births, life-expectancy and immigration.
