Bydd yr ONS hefyd yn ystyried sut mae gwella’r ystod o ystadegau ar y Gymraeg ymhellach drwy edrych ar sut i gasglu gwybodaeth am bobl sy’n gallu siarad Cymraeg ond sy’n byw y tu allan i Gymru.
The ONS will also consider how to further improve the range of statistics on the Welsh language by looking at how to collect information about people who are able to speak Welsh but live outside Wales.
