Chapter 4. Summary Level Sequence Chart
Summary levels specify the content and the hierarchical relationships of the geographic elements that are required to tabulate and summarize data. In the Summary Level Sequence Chart that follows, the summary level code precedes the summary level area, and symbols are used with special meaning for summary levels.

Hyphen "-" separates the elements of a hierarchy. Slash" /" denotes equivalent elements that have different names. Parentheses "()" are not used in the specification for summary levels, but are used occasionally in the usual and customary manner in statements of clarification.
