Understanding these figures
Running costs and works: what is the difference?
Running costs are each year’s spending: wages, energy, upkeep, grants. Works create or renovate something that lasts: a school, a road, a sports hall.
How is the comparison with towns of the same size made?
The median is the middle value among towns of the same size. A value above or below it is not a judgement.
Where do these figures come from?
