My blog has been running a series of posts on the 2011 census returns on the Welsh language recently.
The latest post looked at the relationship between the ability to speak the Welsh language & immigration levels in 12 wards in different parts of the country. BlogMenai.com: I ble'r aeth Saeson Caernarfon?
When I looked at my own town (which saw a decline of 0.5% in the percentage of Welsh speakers) I was surprised at the extent of immigration from outside the UK. In fact there are more people born outside the UK than there are born in England. Had the East European immigration not happened there's little doubt that the percentage of Welsh speakers would have increased substantially locally.
Is this replicated in Ireland? Ie - is there East European immigration into Gaeltacht areas & is it having an impact on the vitality of Irish as a spoken medium?
