Which of the following is a component that maps typically include?

Maps typically include legends, which are crucial for understanding the symbols, colors, and patterns depicted on the map. A legend provides explanations for the various features represented, allowing users to interpret the information accurately without ambiguity. For example, if a map uses different colors to represent various land uses, the legend will specify what each color means, such as residential, commercial, industrial, etc.

While population indices, time zone maps, and economic data can be informative, they are not standard components that all maps must include. Each of these elements can enhance specific maps, but the presence of a legend is fundamental across nearly all types of maps to convey necessary context and make the information accessible to users.
