Classification of Non-official Language(s) 2016
In this classification, category labels refer to languages. For example, "Portuguese" is understood to mean "Portuguese language".
The classification version of 'Non-official Language(s) 2016' differs from the list version in that it excludes 'n.o.s.' (not otherwise specified) categories. These categories are excluded from classifications as they do not uphold the principle of mutual exclusivity required of classifications.
