The line chart illustrates the birth rate of females in six distinct age groups in the UK between 1973 and 2008. Overall, the percentage of birth increased over time among almost age groups, expect for the 35 – 39 year olds and the 30 – 35 year olds.
In 1973, the birth rate of women who were under 20 was 60 per 1,000 people , followed by a slight decline to 40 by the end of the period. The figure for females aged from 20 to 25 stood at over 120 per 1,000 people in the beginning; however, it experienced the same trend as the figure for the under 20 year olds, after dropping to under 120 from 1978 to 1983, and gradually decreased to nearly 90 per 1,000 people in the final year. Regarding the birth rate of the 20 – 25 year olds, the 35 – 39 year olds, and the 40 and over women, it started at nearly 40, 70 and 20, respectively, before slightly growing to more than 85, 65, and 10 per 1,000 people in 2008.
In contrast, females who were 25 – 29 year old had the birth rate at 140 per 1,000 people. Although the birth rate of this group fluctuated during the period from 1978 and 2003 and fell to 120 in 2008, it still maintained the position as the age group giving most birth.
