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.
1State, District of Columbia, or Puerto Rico.
2Parish in Louisiana, borough or census area in Alaska, and municipio in Puerto Rico; in Maryland, Missouri, Nevada, and Virginia, one or more cities are independent of counties and are treated as statistical equivalents of counties; the entire District of Columbia, which has no counties, is treated as a county equivalent.
3In Puerto Rico, some subdivisions (barrios-pueblo and barrios) are divided into subminor civil divisions (subbarrios).
4American Indian Area/Alaska Native Area (Reservation or Statistical Entity Only) includes American Indian Reservations; Oklahoma Tribal Statistical Areas (OTSAs); Tribal Designated Statistical Areas (TDSAs) (federal areas); State Designated American Indian Statistical Areas (SDAISAs) (state areas); and Alaska Native Village Statistical Areas (ANVSAs) (Alaska).
