These tables put the five dimensions side by side. They are the fastest way to see how the same code number means different things in different dimensions — 4000 is social, institutional, or infrastructure-related activities in the activity dimension but transportation, communication, information, and utilities in the function dimension — and they are a convenient basis for a lookup table or a validation list.

One-digit level

The nine top-level categories of each dimension.

Code	Activity	Function	Structure	Site	Ownership
1000	Residential activities	Residence or accommodation functions	Residential buildings	Site in natural state	No constraints — private ownership
2000	Shopping, business, or trade activities	General sales or services	Commercial buildings and other specialized structures	Developing site	Some constraints — easements or other use restrictions
3000	Industrial, manufacturing, and waste-related activities	Manufacturing and wholesale trade	Public assembly structures	Developed site — crops, grazing, forestry, etc.	Limited restrictions — leased and other tenancy restrictions
4000	Social, institutional, or infrastructure-related activities	Transportation, communication, information, and utilities	Institutional or community facilities	Developed site — no buildings and no structures	Public restrictions — local, state, and federal ownership
5000	Travel or movement activities	Arts, entertainment, and recreation	Transportation-related facilities	Developed site — nonbuilding structures	Other public use restrictions — regional, special districts, etc

9000	No human activity or unclassifiable activity	Agriculture, forestry, fishing and hunting	No structure	Unclassifiable site development character	Not applicable to this dimension

Two-digit level

The second level of each dimension, grouped by top-level category. A dash means the dimension has no code at that number — the dimensions are not parallel below the first digit, and no meaning should be inferred from a shared code across dimensions.
