typegrunnlag

Typegrunnlag is a Norwegian term that denotes the basis or foundation used to define or classify a type or category of something. The word combines type (category or kind) with grunnlag (basis or foundation). In Norwegian public, administrative, and technical language, typegrunnlag refers to the set of criteria, data, rules, and assumptions used to determine which type an object, process, or entity belongs to.

The concept is used across several fields. In data management and information systems, typegrunnlag describes the typology framework—the attributes, data sources, and decision rules that specify how records are assigned to a type. In policy, regulatory, or legal contexts, it can refer to the factual and normative grounds for categorizing something under a given type, such as classification for reporting or compliance. In planning and research, typegrunnlag denotes the underlying basis for a typology used in analysis, forecasting, or design.

Because typegrunnlag is a descriptive phrase rather than a fixed technical term, its precise meaning depends on context. It is closely related to concepts such as classification and typology, and it often intersects with discussions of definitions, criteria, and data sources used to group objects or phenomena.

Example: in a municipal planning process, the typegrunnlag for a housing typology might include zoning rules, building heights, and intended land use. See also classification, typology, and grunnlag.
