neartotality

Near-totality is a term used to describe the state of being nearly complete or covering almost all of a defined domain. It signals high, but not absolute, completeness or ubiquity. The phrase is not a standard technical term in most disciplines, so its precise meaning is context-dependent and defined by the tolerance or margin of error specified in a given situation.

In quantitative contexts, near-totality is often operationalized as a proportion within a small margin ε of a referent total. For example, a data-collection effort achieving a coverage rate of 0.999 or higher might be described as exhibiting neartotality with respect to sample inclusion. In set-theoretic or probabilistic language, this may loosely correspond to properties that hold for all but a negligible subset of cases, though it is not a formal synonym for “almost surely” or “almost everywhere” unless the user defines it as such.

Applications and examples include: data completeness in surveys where only a tiny fraction of responses are missing; software test coverage described as near-total when most code paths are exercised; ecological surveys noting near-total detection of species within surveyed plots; and reporting where a characteristic applies to nearly every instance in a population.

See also: almost everywhere, almost surely, completeness, extensive coverage. Etymology: from near and totality, reflecting the intended meaning of “almost complete.”
