These articles have info boxes in which there is an estimate of the number of speakers, but no date has been entered into the date field. That field tracks the age of the data and flags it when it is more than a certain number of years old. (Currently set to 30.) Articles do not appear here when the field is purposely set to no date, meaning that the reference itself (typically Ethnologue) lacks a date for the data.

Articles with ISO3 codes have been reviewed with Ethnologue 17. Some remaining dialects may be datable with the parent ISO code.
