The pie charts illustrate the ages of people employed in the UK public sector during two years, 2015 and 2020. Overall, while the percentage of those employed in their 20s and 40s increased, employment for other ages groups, particularly the over 50s, fell.
Turning first to the younger age groups, although the employment of workers under 21 actually fell from 14% in 2015 to 12% in 2020, the overall number of workers under 30 actually rose because of the surge in employment of 21-30 year olds, which increased significantly from 23% to 33%. Similarly, the number of employees over the age of 40 climbed from 19% in 2015 to 28% by 2020.
However, other groups saw quite significant falls in employment. For 31-40 year olds, the employment figure plummeted from 21% in 2015 to just 11% by 2020, which represented a substantial drop of more than 50% in relative terms. Likewise, the employment of over 50s declined, though not by quite so much, standing at 23% in 2015 and 16% in 2020.
