The line graph compares the birth rate in 6 different age categories in the UK between 1973 and 2008.
Overall, it is clear that people aged 25-29 consistently recorded the highest figures throughout the period, meanwhile the elderly people (40 and over) were the lowest. Another significant observation is that the 35-39 group experienced remarkable increase since 1988.
In 1973, the highest level of birth was in 25-29 group at 140 per thousand. From the start of the period, it decreased to 120 and showed a fluctuation until the end. The age category 20-25 represented a gradual decrease from just over 120 in 1973 to the 100 by 2008, while 35-39 exhibited a slight rise approximately 5 per 1000 within 15 years. However, it experienced sharp growth, reaching over 60 since 1988 and between 1998 and 2008 remained stable.
On the other hand, older individuals aged 30-35 climbed from about 70 and peaked at approximately 85 per thousand. In contrast, younger women (under 20) and elders (over 40) had a decline over the decade. Under 20 fell from 60 to 40, and over 40 remained the lowest throughout, moderately going down from almost 20 to just under 10.
