Updated last year UNESCO's publication Atlas of the World's Languages in Danger” states that no fewer than 390,000 people speak Luxembourgish, an increase! This is contrary to some other media reports.

(ADW) Do you speak Moselle Franconian? That is the official name UNESCO, the United Nations Educational, Scientific and Cultural Organization, uses when referring to Luxembourgish in their “Atlas of the World's Languages in Danger” report, and indeed historically, that's apparently the official name for it.
Call the language what you will, but the report, that was actually updated last year in March as part of UNESCO's publication states that no fewer than 390,000 people speak Luxembourgish in the world, an increase of 90,000 more than originally estimated by the organisation. Since that date there has not yet been a new report revising the figure.
