How many Welsh, Sámi, Sorbs … Are There? Numeric Data on Ethnicity and Language Speakers as Controversial Phenomenon

an apparently straightforward fact as ethnicity/ethnic identity, seemingly easy to measure exactly,
is highly debatable, as it hides a number of pitfalls and difficult-to-answer questions; it is also easy
to manipulate and misuse politically. The same applies to the no less vague and difficult-to-measure phenomena of knowledge/use of language or mother tongue and their registration. The main
emphasis of the text is on the current specific problems of ethnic and linguistic records, which
are documented and analyzed: 1/ at a general level; 2/ on several current examples of European
minority ethnic groups (Welsh, Sámi, Sorbs, Kalmyks, Rusyns). The tradition of ethnic/linguistic
censuses is strong especially in Central and Eastern Europe. The author documents this fact on
the Czech example, which is still based on the Austro-Hungarian model. It follows from the above
that the standard publication of results of ethnic and linguistic censuses – despite their widespread
and apparent exactness – must be received, due to the controversial dimension present, with
considerable caution.
