Note: Children and young people were not asked the question in relation to further and higher education, so these categories provide the percentages of Welsh speakers aged 16 or older.
Noder: Ni ofynnwyd y cwestiwn ar gyfer addysg bellach ac uwch i blant a phobl ifanc, felly canrannau siaradwyr Cymraeg 16 oed neu hŷn a geir yn y categorïau hyn.
