A community indifference curve shows how people in a group might make choices about different things that they could do. For example, it helps you to figure out what people in a group might prefer more - going to the movies or going bowling. On the graph, the different activities are drawn on the bottom axis, and the amount of enjoyment people in the group get from the activity is on the vertical axis. A community indifference curve is like a line that goes from one activity to the other and points towards the activities that people in the group would prefer more.
