The bar chart compares the ages when women had their first child in Australia from 1966 to 2006. Overall, there was a growing trend of later parenthood. While there was a sharp drop in the proportion of women who gave birth at the age of 19 and 20-24, an opposite trend was observed among women aged between 30 and over 40s, with the biggest rises seen among women in their 30s. By contrast, after an initial increase in the percentage of women who decided to have a baby in their late 20s, the figure fell in 2006.
