The given line chart illustrates the transformation in the ratio of birth for females in 6 different age groups in the UK between 1973 and 2008.
Overall, it is evident that women in the 30-34 age group experienced an upward trend over time while the opposite can be seen for those in from under 20 to 24 age group and 40 and over years old. Moreover, the figure for 25-to-29-age female was highest among all.
In terms of women under 30 years old, it is obvious that age ranging from 25 to 29 was the most ideal age to have children. To be more specific, there was a significant decrease to 120 births per 1000 people in 1978, followed by a gradual increase and reaching a peak at just under 140 births per 1000 people after 10 years and a final fall to 120 births per 1000 people in 1978. In contrast, both figures in women aging from under 20 and between 20 and 24 years old showed similar pattern that declined remarkably from 130 to 90 births per 1000 people in 20-24 age group and from 60 bto roughly 50 births per 1000 people under 20 years old over the period.
Regarding the female over 30 years old, while the birth rates of women being between 30 and 34 years old witnessed a moderate growth of around 20 births per 1000 people in the survey, them in 40 and over age growth underwent a gradual drop to just over 0 births per 1000 people in the year 2008. In addition, the figure for 35-to-39-age women rose slightly to just over 40 births per 1000 people in 1983, after which it make a recovery to just over 60 births per 1000 people in the end.
