In the most recent announcement for World Happiness Index Australia ranks 11th.
Current projections indicate that Australia’s population will continue to steadily grow for the rest of the century. Australia’s population is about 25.5 million as of 2020 and is projected to grow to 42.68 million people by 2099.
Australia’s population growth rate is 1.18%, adding about 296,000 people to the population over 2019’s population. This is a result of both net migration, which has been about 150,000 per year for the past few years, and natural increase. Australia’s fertility rate of 1.83 births per woman is below the population replacement rate of 2.1 births per woman.
Australia ranks fifth among OECD countries for population growth. As the other OECD countries with high growth rates, Australia has a strong labor demand that cannot be met from domestic sources; therefore, mass migration occurs.
