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.
There is a positive picture among economic well-being indicators in Quarter 4 (Oct to Dec) 2017; gross domestic product (GDP) per head has grown by 0.8% in real terms compared with the same quarter a year ago and real household disposable income (RHDI) per head has increased by 1.0%.
Net national disposable income (NNDI) per head – which takes account of the depreciation of assets and the UK’s foreign income balance – increased by 2.1% between Quarter 4 2016 and Quarter 4 2017, due mainly to a £4.8 billion increase in the balance of income received from the UK’s foreign direct investment from abroad.
Quarter 4 2017 marks the first quarter that RHDI per head has increased on an annual basis since Quarter 1 (Jan to Mar) 2016 – RHDI per head has been decreasing from Quarter 2 (Apr to June) 2016 to Quarter 1 2017 and it remained flat from Quarter 2 2017 to Quarter 3 (July to Sept) 2017.
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.
