The line graph demonstrates how the rate of birth changed throughout the 36-year period in the UK. The data is provided in six age categories.
Overall, the birth rate in younger generation and people older 40 has declined over the years, whereas the figure for adults between 30 and 40 experienced a growth. Moreover, there were noticeable fluctuations in the another age group older 25.
Examining the youngest three groups, people who are under 20 inclined to give a birth to a baby more frequently before, with the report for 1973 year being 60 birth per 1000 people. It was still a far less than that of adults over 20. While the birth rate of people who are in their early 20s comprised over 120, it was 140 among people who are in late 20s. Additionally, the youngest two age categories decreased constantly, hitting the lowest point of 40 and nearly 90 in 2008. Meanwhile, birth rate of adults between 25 and 29 oscillated throughout the period, and made up around 120 birth per 1000 people at the end.
Now turning to other three figures, birth rate had an ascending tendency when people where in their 30s, whereas the elderly saw a slight decrease. Individuals who are between 30 and 35 increased without sharp changes, starting with about 70, and peaking at over 80 in 2008. However, the figure for adults between 35 and 39 mostly remained constant for approximately 15 years at the beginning, then climbed rapidly to nearly 60 birth. In contrast, the least number of babies were born by the oldest age group, who are over 40. The rate was marginal throughout the whole period compared to others, accounting for 20 birth in 1973, and declining to about 10 after 35 years.
