The line graph gives information about the transforms in the birth rates for females in six age groups in the UK between 1973 and 2008.
Overall, the data for the women aged 30-35 and 35-39 saw an upward trend, while the other age groups declined. In addition, the rate of females aged 25-29 bottomed the list, whereas the opposite was true for the 40 and over group.
Regarding increasing tendency, the data for the 35-39 age group achieved 40 births per 1000 people in 1973, this group started to rise to 62 births in 2008. Likewise, the rate of the 30-35 age group attained 70 births in 1973, this rate increased to 84 births in 2008.
In contrast to that trend, there were 140 births per 1000 people in 1973 in the 25-29 age cohort, at which point the figure experienced fluctuations over 35 years and fell to 120 births in 2008. Younger women followed similar rates of decline over the period, with the 20-25 age group falling steadily from around 120 to 100 births per 1000 people, and those under 20 years old dropping from 60 to 40. Similarly, the proportion of women aged 40 and over dropped by 10 births between 1973 and 2008.
