The graph illustrates the birth rate of British women in six different age ranges between 1973 and 2008.
Overall, it can be seen that the birth rate of women aged 40 and over was the lowest figure. While the number of births recorded in the 30-35 age group demonstrated a slight increase, others experienced downward trends or fluctuations.
The birth rate of women aged 40 and over saw a fluctuation, which reached a peak at the beginning, then the lowest figure was around 120 births per 1000 women. Followed by women aged 20-25, therefore, the number of births in this age range fell significantly by 2008, recording approximately 90 births. The data of women aged 30-35 came third, rising considerably from 70 to over 80 by the end of the period.
The figure for the group of women aged under 20, which is the youngest one, went down sharply by just under 40. In contrast, those in the 35-39 age range witnessed a soar, increasing from 40 to 60 births per 1000 women. The birth rate of women aged 40 and over saw a decline, reaching 15 births by 2008.
