The chart provides data about the age of Australian women when they gave birth to their first child in every 20 years: 1966, 1986 and 2006.
Overall, it is clear from the chart that the figures showed an upward trend for females in the age of between 25-30, 30-34, and 34-39, while women in their age of under 19 and between the age of 19-24 illustrate a downward trend.
In 1966, women, aged 30-34 indicated only a small proportion, and women in the ages of 34-39 displayed an insignificant minority. However, in 1986 their trend increased gradually to about 15% and 18%, respectively. Women at the age of 25-30 and over 40 showed a fluctuation throughout the 60 years.
Looking at the information in more detail, in 1966 the women under 19 showed approximately 34%. However, in 2006 it fell about 12%. The same downward trend was with women in the ages of 19-24, in 1966 by showing a large proportion, but after 20 years it decreased to almost 36%. In addition, this trend also showed a lower percentage in 2006.
