The bar graph shows the proportions of Australian females who had a baby for the first time divided by various age groups over the period from 1966 to 2006.
Overall, rates of younger women who became mothers in the years under 19 and from 19 to 24 decreased noticeably, while medium age in having an initial child became older and that of females above 25 increased steadily over the period given.
According to the graph, the common age was between 20 and 24 to become a mother, and more than 60% of ladies caught their first infant, and about 35% of females were 19 or even younger than this age at the birth of their first child in 1966. However, every 20 years were followed by a falling trend, and in 2006 rates were 30% for the former age category and 10% for the latter one.
When it comes to rising fields, in 1966 less than 40% of women between 25 and 34 years old had their eldest child; however, patterns for these groups rose, and 50% of 25-29-year-old women in 1986 and in the same percent of 30-34-year-olds in 2006 became mothers for the first time. In addition, at the end of the period, females above 35 years old gave their first child more than at the beginning; rates increased from about 10% to 30% throughout the period.
