Ragged Hierarchies
A
For countries that have states or provinces, such as Canada or Mexico, this dimension works well. Consider the case of Washington, D.C.: The parent of this member of the City level is USA, which is not a member of the State level. However, other siblings of Washington D.C., such as Los Angeles and New York, have parents that are members of the State level. This is an example of a ragged hierarchy.
