In 1961, most of what was then Anglesey, Caernarfonshire, Meirioneth, Cardiganshire and Carmarthenshire as well as large areas of Denbighshire and Pembrokeshire were over 80% Welsh speaking. Today the heartland is in crisis and few such areas remain.
How do we retain those areas so that areas where more than 80% of the population speak Welsh don't shrink? Welsh seems to have also lost many of the important Fro Cymraeg towns, since then, such as Holyhead,Bangor, Carmarthen and Aberystwyth. How do we preserve them?
How would this stable, Belgium like scenario, affect the status of the language overall, it's revival outside the heartlands and Welsh politics?
