2021ongoing

2021ongoing is a label used in some data annotation, media analysis, and scholarly discussion to denote events or developments that began in the year 2021 and have continued into subsequent years. It is not an official or standardized term, and its usage varies across different datasets, publications, and research contexts.

The term appears in contexts where researchers distinguish between events that started in 2021 and those with earlier or later origins. It is often applied to broad processes rather than singular incidents, encompassing trends, policies, or conditions that persist beyond 2021. As an informal tagging convention, 2021ongoing can be found in longitudinal studies, archival tagging, and corpus labeling intended to support analyses of ongoing impact.

Criteria for inclusion are generally that the event or phenomenon has a clearly identifiable starting point in 2021 and is expected to continue past that year, with no definitive end date as of the present. Because it is informal, the exact scope can vary and may overlap with related labels such as 2021-present or items categorized under the broader 2020s.

Notable limitations include vagueness and potential overlap with other time-based labels, which can hinder comparability across datasets. Users should specify criteria and context when applying the label to ensure transparency and reproducibility.
