In Australia, the crude birth rate in 1800 was 45 births per thousand people, meaning that 4.5 percent of the population had been born in that year. In the first half of the nineteenth century, Australia's crude birth rate decreased gradually, reaching just under 36 in 1850, however it then increased again over the next fifteen years, as the gold rushes brought many immigrants to the continent. After this, the crude birth rate dropped gradually until the Second World War, after the war Australia experienced another baby boom, reaching it's peak of 23 children per thousand in 1955. In the late 1970s the rate dropped rather sharply, falling from around twenty in 1970 to 15.8 in 1980, and since then the birth rate has decreased at a slower rate, and has fallen below thirteen births per thousand people in 2020.
