Mae’n amlwg yn bwysig, lle bo’n bosibl, i foderneiddio’r ffordd y gwneir pethau, a nodaf fod yr Ystadegydd Gwladol hefyd wedi argymell cynyddu’r defnydd o ddata gweinyddol ac arolygon er mwyn ychwanegu at ystadegau Cyfrifiad 2021 a gwella ystadegau blynyddol rhwng dau gyfrifiad.
It is clearly important where possible to modernise the way things are done and I note that the National Statistician has also recommended the increased use of administrative data and surveys in order to enhance the statistics from the 2021 Census and improve statistics between censuses.
