The graph below shows the changes in UK birth rate of women in 6 different age groups from 1973 to 2008

The line graph illustrates the number of women per 1000 people gives birth in different age groups in England between 1973 and 2008.

Overall, the figures for women aged from 30 to 39 experienced an increase, while those of other groups share the same downward trend after 35 years.

In 1973, in UK, the highest number of births – 140 per 1000 people – was recorded among the 25-29 age group while that number of those aged 20-25 was above 120. In contrast, the figures for women under 20 and over 40 initially were 60 births and 20 births, respectively. During the span of time, despite some mild fluctuations, there was a decline in the birth rate of all these groups and the order was unchanged. For example, those aged 25-29 continuously gave the most births with 120, followed by the 20-25 years old with under 100 births in 2008.

On the other hand, there was a gradual rise of 10 births to over 80 births in the figure for women from 30 to 35 years old by the year 2008. Likewise, after remaining stable in the first 15 years, that figure for those aged 35-39 went up moderately to reach 62 births in the end.
