Given is a bar chart providing us with an aged-based comparison associated with women in Australia bearing their first child in 30 years intervals, commencing in 1966 and coming to a close in 2006.
From an overall perspective, it is starkly apparent that as time progresses, women have less inclinations to undergo childbirth at a younger age.
Looking at the figure in 1966 reveals that more than 60% of the babies were given a birth when their mothers were between the age of 19-24, being almost as double as ones who delivered their first child when they were under 19 and 25-30 (33 and 35%, respectively). As women aged, the birth rate decreased, wavering around 10%. In 1986,however, the natality index for the first born was the highest at the age 25-30, about 50% ,with ladies aged 19-24 being the second highest, almost 10% lesser. Adult women who were under 19, 30-39 had their first born almost half the amount, in the proximity of 20% , while individuals over 40 accounted for only 3%.
Turning to the latter part of the bar chart, women in their mid 30s had the highest fertility rate (50%), followed by 25-30 year old women, representing roughly 38%. Adults with the age of 19-24 and 34-39 were in the vicinity of 30% and likewise over 40 years old women had the lowest quota, standing at about 5%.
