Ers y diweddariad diwethaf ar 16 Ebrill 2013, mae’r Grŵp wedi canolbwyntio ei sylw ar waith casglu tystiolaeth er mwyn ei gynorthwyo i weld pa ffactorau penodol ac uniongyrchol sy’n berthnasol i dwf economaidd, darparu swyddi, creu cyfoeth a lles y Gymraeg.
Since the last update provided on 16 April 2013, the Group has focussed its attention on evidence gathering activities to help identify the factors that have specific and direct relevance to economic growth, the provision of jobs, the creation of wealth, and the well-being of the Welsh language.
