I've attached a sample of geographic code for selected summary levels in
the 1990 Census. In doing this I found a need for 2 or three additional
elements to identify the location of a variable that described the
structure of geography and also to identify whether cover was exhausive
within the parent geography. For example all places versus places of over
1,000 persons. This is different from the concept of geographically
exhautive, where a True would indicate border to border coverage and no
"holes".

The added elements are highlighted in red.
