Mae mesur lles cenedlaethol yn ymwneud ag edrych y tu hwnt i'r hyn a gynhyrchir gennym, i feysydd megis iechyd, perthnasau, addysg a sgiliau, yr hyn rydym yn ei wneud, lle'r ydym yn byw, ein sefyllfa ariannol a'r amgylchedd. Mae hefyd yn mesur ein lles personol, asesiad unigolyn o'i les ei hun. Daw'r data hyn o amrywiaeth o ffynonellau, ac mae llawer o'r gwaith dadansoddi yn newydd.
In Quarter 3 (July to September) 2016, gross domestic product (GDP) per head increased 0.4% compared with Quarter 2 (April to June) 2016 and is now 1.5% above pre-economic downturn levels. This was a slightly slower growth rate than the 0.6% quarterly increase seen in GDP.
Net national disposable income (NNDI) per head increased by 0.6% in Quarter 3 2016 compared with the same quarter a year ago. This means that NNDI per head reached its pre-economic downturn peak for the first time in Q3 2016. GDP per head reached this yardstick in 2015 Q3.
In Quarter 3 2016, real household disposable income (RHDI) per head excluding non-profit institutions serving households (NPISH), decreased 0.2% compared with the same quarter a year ago.

Where there are sufficient data to be compared, measures have been assessed over the long-term and short-term to show if there has been clear improvement, deterioration or if there has been little or no overall change.
