Final answer:
Occupancy classifications like Assembly and Institutional have implications beyond occupant load, affecting many design aspects of a building and sometimes the incorporation status of a location.
Step-by-step explanation:
The question pertains to the occupancy classifications within building codes, specifically the different subcategories such as Assembly and Institutional and their effect not only on occupant load calculations but on a variety of other building requirements. These classifications not only determine the likely population density of certain areas within a project but also influence various design requirements such as egress design, fire protection systems, building construction types, and allowable building heights and areas. The classification can impact the incorporation status of the location and, by extension, requirements for non-residential urban land use, like factories or large airports, which the Census might account for based on measures like surface imperviousness and population density.
