An indicator is something that helps you understand where you are, which way you are going and how far you are from where you want to be. It can also alert you to a problem before it gets too bad and help you recognize what needs to be done to fix the problem.
Sustainability indicators reflect the reality that the three different segments (economic, social and environmental) are very tightly interconnected. They are useful to different communities for different reasons, but for all communities, indicators can generate discussion among people with different backgrounds and viewpoints, and, in the process, help create a shared vision of what the community should be.
