Wikidata:Database reports/identical birth and death dates

These are pairs of items with identical dates in date of birth (P569) and date of death (P570). Some can be merged, others not (different persons with the same or incorrect dates). The list is updated daily by bot (items with corrected or removed dates can take two days to be removed from the list).

How probable are false positives?

  • Items for people with both dates: 1550757 ()
  • Pairs of items with a …% probability of identical dates: …

Items in the list below could be:

Type Sample Suggested approach
Items about the same person merge the two items
Items about the same person merge the two items
Items about the same person delete the redirect-sitelink and merge the two items. Special:MergeItems can sometimes merge them directly.
Items about the same person merge the two items
Items about the same person delete the sitelink to the disambiguation page and merge the two items (sitelink didn't get updated on pagemove)
find a new item for the disambiguation page or create it
Items about different people, with incorrect dates and possibly mixed-up sitelinks correct dates and/or fix sitelinks. Don't merge. If in doubt, use the articles' talk pages or WD:IWC
Items about a person and items with dates they shouldn't have remove dates from the item that shouldn't have them
Items for identical persons, but with two articles at the same Wikipedia possibly suggest to Wikipedia to merge both adding Template:Merge (Q6919004) to each article
mark one with instance of (P31): Wikimedia duplicated page (Q17362920) and qualifier of (P642) linking to the other item
Alternatively, interlink both with said to be the same as (P460)
possibly move statements to the one item that isn't marked with Wikimedia duplicated page (Q17362920)
Once the merge of the articles completed, the items can be merged
False positives: two different persons, with same dates of birth and death

double-check dates, ideally with references
interlink both items with different from (P1889)
add items to False_positives

Already merged/fixed some of the below (items redirected, labels and statements appear then as identical) do nothing ;)

Steps:

  • Are both items about the same person?
    • If yes:
      • Can the items be merged?
        • If yes: merge them. In the next update, the pair will disappear from the list
        • If no: tag the two articles at Wikipedia for merging. In the next update, the pair will be moved to the "marked for merging" section of the main list.
    • If no:
      • Are the P31 values correct?
        • If no: correct them
      • Should the item have P569/P570?
        • If no: remove them. In one of the next updates, the pair will disappear from the list.
      • Are the dates correct?
        • If no: correct them. In one of the next updates, the pair will disappear from the list.
        • If yes: add the pair to "false positives". In the next update, the pair will disappear from the list.
