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 line with recent trends, there is a mixed picture among economic well-being indicators in Quarter 3 (July to Sept) 2017; gross domestic product (GDP) per head has grown 1.1% in real terms compared with the same quarter a year ago, but real household disposable income (RHDI) per head has declined 0.2%.
Net national disposable income (NNDI) per head – which takes account of the depreciation of assets and the UK’s foreign income balance – increased by 1.5% between Quarter 3 2016 and Quarter 3 2017, due mainly to a £2.6 billion increase in the balance of income received from the UK’s foreign direct investment from abroad.
Between Quarter 4 (Oct to Dec) 2015 and Quarter 3 2017, NNDI per head increased by 5.4% compared with a contraction in RHDI per head of 1.6%; this divergence is due to an increasing share of national income accounted for by corporations and government, and a lower share to the households sector.

An assessment of UK progress against a set of headline national well-being indicators, which include our health, natural environment, personal finances and crime. Change over time is also assessed to establish whether national well-being is improving or deteriorating.
The Sustainable Development Indicators (SDIs) provide an overview of progress towards a sustainable economy, society and environment. There are 12 headline and 23 supplementary indicators, supported by 25 and 41 measures respectively. 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.
