The bar chart illustrates the average age of the females who gave birth to their first baby in Australia in three different years.
Overall, it is evident from the information presented that the Australian female giving birth to the first child figure was a considerable increase between two age groups, which include 30-34 and 35-39. Of particular note, 19 and over reached their highest percentage in 1966, while this figure dramatically decreased after two decades. However, 40 and over was always the lowest percentage of women giving birth to their first child.
In 1966, the highest result belonged to 20- and 24-year-old females, which approximately displayed 62 percent giving birth to their first child, but from 1986 onwards, there was a pronounced decrease, reaching its lowest point (30%) in 2006, whereas 19 and under and 25-29 registered the same results in 1966, which consisted of nearly 38%, but the former group’s percentage dramatically went down after twenty years. In contrast, the latter point was altering increases and decreases over the last two decades (50% and 41%) delivering their initial offspring.
Regarding first childbirth, both 30-34 and 35-year-old Australian women demonstrate differing figures in the bar chart. As a matter of fact, the 30-34 age group roughly showed more 4% than the 35-39 age group in 1966. Statistically, there was consistent growth in both groups in 1986, with a sharp spike observed towards the end of the period.
Finally, 40 and over was a gradual increase over 40 years, with its highest result registered in 2006, namely 5%. Although it was the lowest figure compared to other age groups about delivering to their initial offspring,.
