An economic map is a map that illustrates various economic activities or phenomena that take place in a particular area. This type of map features a variety of symbols and colors referring to particular economic activities. General economic maps aim to describe whole economies. These maps show a large area, complete with its economic regions, territorial-production complexes, economic centers, economic ties, levels of economic development and specialization of production. Economic maps may also feature labor resources and natural resources as components of economic activity. Some of the first economic maps appeared in Russia in the late 17th century and were drawn by hand.
