This notability guideline for reflects consensus reached through discussions and reinforced by established practice, and informs decisions on whether an article about past, current, and breaking news events should be written, merged, deleted or further developed.

In evaluating an event, editors should evaluate various aspects of the event and the coverage: the impact, depth, duration, geographical scope, diversity and reliability of the coverage, as well whether the coverage is routine. These factors are described below.

Events are often considered to be notable if they act as a precedent or catalyst for something else. This may include effects on the views and behaviors of society and legislation. For example, the murder of Adam Walsh ultimately led to the Adam Walsh Child Protection and Safety Act, among other notable subjects.

Events that have a noted and sourced permanent effect of historical significance are likely to be notable. This includes, for example, natural disasters that result in widespread destruction, since they lead to rebuilding, population shifts, and possible impact on elections. For example, Hurricane Katrina or the 2004 Indian Ocean earthquake are notable by these standards. A minor earthquake or storm with little or no impact on human populations is probably not notable.

It may take weeks or months to determine whether or not an event has a lasting effect. This does not, however, mean recent events with unproven lasting effect are automatically non-notable.

An event affecting a local area and reported only by the media within the immediate region may not necessarily be notable. Coverage of an event nationally or internationally may make notability more likely, but such coverage should not be the sole basis for creating an article. However, events that have a demonstrable long-term impact on a significant region of the world or a significant widespread societal group are presumed to be notable enough for an article.

The general guideline is that coverage must be significant and not in passing. In-depth coverage includes analysis that puts events into context, such as is often found in books, feature length articles in major news magazines (like Time, Newsweek, or The Economist), and TV news specialty shows (such as 60 Minutes or CNN Presents in the US, or Newsnight in the UK). Reporting with little thematic connection or contextual information is often considered to be routine reporting. Some editors consider narrative news reports to be primary sources rather than secondary sources.
