List of Welsh principal areas by percentage Welsh language

This is a list of subdivisions of Wales by the percentage of those professing some skills in the Welsh language in the 2011 UK census. The census did not record Welsh-speakers living outside Wales.

The census determined that 85.43% of the population could not read, speak or write in Welsh and that 80.99% of the population could not speak Welsh.

The Census produced a detailed breakdown of skills as:

For the purpose of the first table, all combinations other than "no knowledge of Welsh" have been combined, giving a percentage of people that state they have some communication skills in the Welsh language rather than an ability to speak Welsh. The totals include children whose parents have filled in the Census details on their behalf.

The second table includes only those people who stated in the 2011 Census that they are able to speak the Welsh language. It was these statistics that were reported by the press when the first data samples were released in 2012.
