The given line chart illustrates the changing birth rate in 6 different age groups in UK between 1973 and 2008.
Overall, there was an increase in two groups: 30-35 and 35-39 age group , while others showed decreases. In addition, while the 25-29-year-old cohort maintained the highest position, the oldest one showed an opposite pattern throughout the period examined .
Looking first at the 25-29 age group, whose figure exhibited noiceable fluctuations during the period of time, the figure remained the highest age group during the first 10 years, albeit falling from around 140 to 120 individuals. Thereafter, the statistics of 20-to-25-year-old cohort sharply rised to approximately 135 people in a period of 10 years starting from 1983, however, it strongly dropped to below 120 people and sightly recovering and stabilizing at around 120 until the end of the period.
Moving to the two categories with changing ranking, the data for under 20 age group showed a consistent decrease throughout the period examined, dropping from 60 at the beginning to around 40 people by the end. In contrast, the figure for 35-39 age group exhibited a upward trend during the majority of the period, it sightly increased from 40 in the first half of given course, surpassing the under 20 age group, and stabilized approximately 70 through to the end of the period.
Turning to finally three group, the figure for 25-29-year-old cohort displayed a steady decline over the period analyzed, dropping from over 120 people to around 100, albeit remaining the second highest individuals group. Similarly, the 40 and over age group showed a downward trend throughout the period, decreasing significantly from 20 to around 10 people until the period’s end. By contrast, the figure for 30-35 age group increased from around 70 to 80 in the first half of the period and stabilized during the end of given course.
