Category:Language articles without reference field

These articles have infoboxes with speaker information but without anything in the ref field. This can be an indication that the speaker numbers are unsourced, but the absence of the ref field is not by itself a problem. For example, the infobox can simply repeat or summarise information that's discussed and sourced elsewhere in the article.

This category is not triggered where "speakers" is set to "?" or "none" (triggering "unknown" or "None"), by "extinct" or "era" instead of "speakers". It is not triggered by citation needed or either. For languages with ISO codes that have a "citation needed" tag in the ref field, see Category:Articles with citation needed in ref field; for those with &amp;nbsp;, see Category:Articles opting out of population reference.
