Deer are found on forest and tundra tiles, mainly in the polar (northernmost/southernmost) regions of the world. They typically provide a significant fraction of available Food in the otherwise barren polar regions of the map, making their presence and exploitation an important factor in sustaining strong cities in these areas. Building a Camp will further enhance the Gold yield of Deer once you have researched Economics, making them valuable to your empire's economy as well.
Note that building a Camp does not require clearing the underlying forest. This allows continued exploitation of the additional Production provided by the forest itself, for a base yield of 2 Food and 2 Production from a Camp built on a forested tundra tile with Deer. When the terrain beneath the forest is tundra, one should preserve the forest where possible, since clearing it will result in a net loss of 1 Production. However, if the terrain is plains, then removing the forest will not change the tile yields because both forest and plains give 1 Food and 1 Production. Thus, one should always clear the forest of a Deer on a plains tile before constructing the Camp.
Deer and their relatives - reindeer, moose, roe, etc. - can be found in herds across the planet. They have provided food, leather, bones, gut, and other materials for pre-industrial people for uncounted thousands of years.
