The line graph provides information about the natality rate among six different age groups in United Kingdom between 1973 and 2008.
Overall, the birth rates in the age groups 35-39 and 30-35 increased over the period given, while four other age cohorts decreased. Despite the changes happened in 35 years, women aged 25-29 remained substantial, as well as women from 40 and over category – a meager proportion.
With regard to the women aged 20-25, over the time they experienced a steady downward trend. Starting approximately at 125 in 1973, they ended up at around 95 births in 2008. A similar trend was observed among females who were under 20. Their birth rate numbers decreased significantly, by almost 20 per 1000 people, as in 1973 the rate was at around 60, and dropped by about 40 by 2008. In addition, the birth rate among women aged 40 and over in 1973 constituted nearly 20, and by 2008 this number slightly reduced to toughly 10.
In contrast, the labour among ages 35-39 represented substantial growth over the period. It began at around 40, peaked at nearly 41 in 1988, and then rose dramatically to about 62 by 2008. Similarly, nearly 71 births were given among women ages 30-35 in the first year, after which this figure increased slightly to 83 in 2008. Finally, the rates of 25-29 age group was the most unstable, as in the beginning it was on the peak (140), after which the figure fluctuated considerably before dropping at approximately 120 in 2008.
