momentopname

Momentopname is a Dutch term used to denote a snapshot or single observation of a system at a specific moment in time. The word combines moment and opname (recording or capture). In research, journalism and data analysis, a momentopname records the state of variables at one point, in contrast to time-series data or longitudinal studies that track changes over time.

Applications and usage: In meteorology, a momentopname refers to weather observations taken at a particular time, such as temperature, humidity, and wind speed. In economics or finance, it can describe an instantaneous set of indicators, like prices, volumes and exchange rates, observed at a single moment. In social sciences and market research, it can denote cross-sectional survey results captured at a particular date.

Methodology and interpretation: Because it represents a single moment, a momentopname may not reflect typical conditions and is susceptible to short-term fluctuations. It is most useful for describing a state at a defined time or for comparisons across places or groups at the same moment. When studying change, momentopnames are usually combined with time-series data or multiple snapshots.

Etymology and synonyms: The term is of Dutch origin, literally 'moment' plus 'opname' (recording). In English, it is often translated as snapshot or point-in-time observation.
