What a Survey Is.
A survey is an attempt to record existing conditions. It gives:
1. A general view.
2. A more particular or intensive study of the various parts of the whole and their relation to one another.
It may include recommendations for improvement, but its primary purpose is to record what actually exists.
The survey is a systematic study of existing conditions. Those making it have always a well-defined plan in mind. It is necessary, in order to maintain a proper balance for the completed survey, to give a properly proportioned representation of what happens, with no element omitted or over-emphasized.
