Notably, Caerphilly has a very high proportion of houses compared to flats - 91 per cent vs nine per cent - but still took the top spot in Wales overall.

Torfaen placed third in the top five, just below Cardiff, but above Wrexham and the Vale of Glamorgan.

The worst areas in Wales were Pembrokeshire, Carmarthenshire, Powys, Ceredigion, and Gwynedd – all with scores under 60.

No Gwent areas were in the bottom five.
