Every other measured marital group (single, married or partnered, currently separated, divorced) had no differences from each other or the national average.
Nid oedd gan bob grŵp priodasol mesuredig arall (sengl, priod neu â phartner, wedi gwahanu ar hyn o bryd, wedi ysgaru) unrhyw wahaniaethau oddi wrth ei gilydd na'r cyfartaledd cenedlaethol.
