You can use label classes to label only a subset of features in a layer. For example, you might label only cities with a population greater than 1,000,000.
You can specify a different label field, symbol, scale range, label priority, and set of label placement options for each label class.
Label classes allow you to use a different text symbol to label different types of features in the same layer. For example, you can label cities with a large population in a larger font than those with a smaller population.
