Band 9: The chart below shows the proportion of staff employed by age in the public sector in the UK in 2015 and 2020. Summarize the information by selecting and reporting the main features and make comparisons where relevant.

The two pie charts illustrate the distribution of public sector employees in the UK by age group in 2015 and 2020.

Overall, the workforce became younger in 2020, with a noticeable increase in the proportion of employees aged 21-30, while the shares of older age groups declined.

In 2015, the largest proportions were seen in the 21-30 and over 50 age groups, both at 23%. Employees aged 31-40 accounted for 21%, followed by those aged 41-50 at 19%. The smallest group was under 21, representing 14% of the workforce.

By 2020, the 21-30 group had grown significantly to 33%, becoming the dominant category. In contrast, the proportion of workers over 50 decreased sharply to 16%. Similarly, the 31-40 group fell to around 11%, the lowest among all categories. However, the 41-50 group increased to 28%, making it the second-largest segment. The percentage of staff under 21 showed a slight decline to 12%.

In summary, the data indicates a shift towards a younger workforce, particularly among those in their twenties, alongside a reduction in older employees.
