Hierarchy Diagrams

The standard hierarchy of census geographic entities displays the relationships between legal, administrative, and statistical boundaries maintained by the U.S. Census Bureau. The hierarchy provides a quick and easy way to see how the different geographic entities at the Census Bureau relate to one another. In other words, it shows how different geographic areas may, or may not, be related. It depicts relationships with a line and shows where relationships do not exist by displaying entities on different line tracts.
