Depicted in the chart is information about how old women (divided into six different groups) were when they had first child over a forty-year period from 1966 to 1986 and 2006. Overall, what stands out from the graph is that the number of women having a baby at under 24 years of age witnessed a downward tendency, while the other ages experienced a reverse trend. Another fascinating point is that the oldest women remained the least number.
As regards the 30-34 age bracket, despite starting at just under 15%, the ratio had increased significantly to nearly 50% by the end, making it ahead of list. Women who became mothers at ages 34-39 also went up considerably to exactly 30%. This was followed by the oldest group, which also saw a very small growth to approximately 5%.
If we look at the 19-24 age cohort, despite starting at just over 60%, women becoming mothers at this age had fallen by 2006 to just under 30%. The same trend was also experienced by the youngest group, which plummeted from 30% to slightly over 10% at the end of the period. In contrast, having climbed to 50% in 1986, the number of women having a baby at ages 25-30 went down to just under 40% twenty years later.
