Welsh: Mae data ynglŷn â Safon Ansawdd Tai Cymru (ar lefel Cymru) ar gael yma:
English: Data are also available for the Housing Health and Safety Rating System (HHSRS).
Welsh: Mae data ar gael hefyd ar gyfer y System Mesur Iechyd a Diogelwch ar gyfer Tai.
English: It is a risk-based evaluation tool to help local authorities identify and protect against potential risks and hazards to health and safety from any deficiencies identified in dwellings and used to determine whether residential premises are safe to live in or whether a hazard exists that may cause harm to the health and safety of a potential occupant.
Welsh: Offeryn gwerthuso ar sail risg yw hwn, i helpu awdurdodau lleol i nodi a diogelu rhag risgiau a pheryglon posibl i iechyd a diogelwch o ganlyniad i ddiffygion a nodwyd mewn eiddo. Fe'i defnyddir i benderfynu a yw eiddo preswyl yn ddiogel i fyw ynddo neu a oes perygl yn bodoli a allai achosi niwed i iechyd a diogelwch preswylydd posibl.
English: Whilst it covers all residential premises it is usually used to assess standards in private sector housing.
Welsh: Er ei fod yn cwmpasu pob eiddo preswyl, fe'i defnyddir fel arfer i asesu safonau mewn tai yn y sector preifat.

English: Homes with poor energy efficiency performance are more difficult/expensive to heat.
Welsh: Mae tai sy'n defnyddio ynni'n aneffeithlon yn fwy anodd/drud i'w gwresogi.
English: An Energy Performance Certificate (EPC) is required for properties when constructed, sold or let.
Welsh: Mae angen Tystysgrif Perfformiad Ynni (EPC) ar gyfer eiddo pan gânt eu hadeiladu, eu gwerthu neu eu gosod.
English: The EPC provides details on the energy performance of the property and what can be done to improve it.
Welsh: Mae'r EPC yn rhoi manylion am berfformiad ynni'r eiddo a'r hyn y gellid ei wneud i'w wella.
English: Work to assess the coverage, consistency and quality of EPC data was not completed in time to feed into the WIMD 2014 process.
Welsh: Ni chwblhawyd gwaith i asesu cwmpas, cysondeb ac ansawdd data EPC mewn pryd i'w bwydo i broses MALIC 2014.

English: The geographic areas used in the calculation of WIMD 2014 are the 1,909 Lower layer Super Output Areas (LSOAs).
Welsh: Yr ardaloedd daearyddol a ddefnyddir yn MALlC 2014 yw'r 1,909 o Ardaloedd Cynnyrch Ehangach Haen Is (AGEHI).
English: LSOAs were used as the geographic unit in WIMD 2005, 2008 and 2011, and were designed for the reporting of small area statistics.
Welsh: Defnyddiwyd AGEHI fel uned ddaearyddol yn MALlC 2005, 2008 a 2011, a chawsant eu cynllunio er mwyn cyflwyno adroddiadau ar ystadegau ardaloedd bach.
English: The other three UK nations also calculate their indexes at the LSOA geographical unit.
Welsh: Mae AGEHI hefyd yn cyd-fynd â'r dull a ddefnyddir gan dair gwlad arall y DU ar gyfer eu mynegeion nhw.
English: Super Output Areas
Welsh: Ardaloedd Cynnyrch Ehangach
English: Following the 2001 Census of Population, the Office for National Statistics developed a geographic hierarchy called Super Output Areas (SOAs).
Welsh: Yn sgil Cyfrifiad 2001, aeth y Swyddfa Ystadegau Gwladol ati i ddatblygu hierarchaeth ddaearyddol o'r enw Ardaloedd Cynnyrch Ehangach (ACE).
English: They were designed to improve the reporting of small area statistics in England and Wales.
Welsh: Fe'u cynlluniwyd er mwyn gwella'r dull o gofnodi ystadegau ardaloedd bach yng Nghymru a Lloegr.
English: Where possible, official statistics are now published at the SOA geography.
Welsh: Erbyn hyn, mae ystadegau swyddogol yn cael eu cyhoeddi'n rheolaidd ar gyfer daearyddiaeth ACE, lle maent ar gael.
English: There are three layers of SOA:
Welsh: Mae tair haen o ACE:
English: Lower layer, Middle layer, and Upper layer.
Welsh: Haen Is, Haen Ganol, a Haen Uwch.
English: This is because disclosure requirements mean that some sets of data can be released for much smaller areas than others.
Welsh: Y rheswm am hyn oedd bod gofynion datgelu yn golygu bod modd rhyddhau rhai setiau o ddata ar gyfer ardaloedd llawer llai nag eraill.
English: To support a range of potential data requirements, it was decided to create these three SOA layers.
Welsh: Felly, er mwyn cefnogi amrywiaeth o ofynion data posibl, penderfynwyd creu'r tair haen arbennig hon. Dyma'r cyfyngiadau:
English: A Lower Layer SOA must have a minimum population of 1,000.
Welsh: Rhaid i ACE Haen Is gynnwys isafswm poblogaeth o 1,000.
English: The mean size of all the Lower Layer SOAs must be close to 1,600.
Welsh: Rhaid i faint cymedrig yr holl Ardaloedd Cynnyrch Ehangach Haen Is fod yn agos i 1,600.
English: They are built from groups of Census Output Areas (usually between four and six).
Welsh: Maent yn seiliedig ar grwpiau o Ardaloedd Cynnyrch y Cyfrifiad (rhwng 4 a 6 fel arfer).
English: A Middle Layer SOA must have a minimum population of 5,000.
Welsh: Rhaid i ACE Haen Ganol gynnwys isafswm poblogaeth o 5,000.
English: The mean size of all the Middle Layer SOAs must be close to 7,200.
Welsh: Rhaid i faint cymedrig yr holl Ardaloedd Cynnyrch fod yn agos i 7,200.
English: SOA boundaries are revised following each Census, to take into account changes in the population.
Welsh: Mae ffiniau ACE yn cael eu diwygio ar ôl bob Cyfrifiad, er mwyn ystyried newidiadau mewn poblogaeth.
English: WIMD 2014 will be the first Welsh Index of Multiple Deprivation to use the revised boundaries, following the 2011 Census.
Welsh: MALlC 2014 fydd y mynegai cyntaf yng Nghymru i ddefnyddio'r ffiniau diwygiedig yn sgil Cyfrifiad 2011.
English: In the 2001 Census, there were 1,896 LSOAs; 49 of these have been discontinued and 61 new LSOAs have been created.
Welsh: Yng Nghyfrifiad 2001, roedd 1,896 AGEHI - mae 49 wedi dod i ben erbyn hyn, a 61 o rai newydd wedi'u creu.
English: There have been changes to LSOA boundaries where populations have:
Welsh: Cyflwynwyd newidiadau i ffiniau AGEHI ar sail y canlynol:
English: become too big, so an LSOA has been split into two or more areas;
Welsh: roedd y boblogaeth yn rhy fawr, felly rhannwyd yr AGEHI yn ddwy ardal;
English: become too small, so an LSOA has been merged with an adjacent one; or
Welsh: roedd y boblogaeth yn rhy fach, felly cyfunwyd AGEHI/AGEHG ag ardal gyfagos; neu
English: changed in a complex way, so there has been a combination of the two cases above.
Welsh: mae'r boblogaeth wedi newid yn sylweddol, felly bu cyfuniad o'r ddwy sefyllfa uchod.
English: Where LSOAs have changed, the old code has been deleted and a new code has been assigned.
Welsh: Lle'r oedd AGEHI wedi newid, cafodd yr hen god ei ddileu a dynodwyd un newydd yn ei le.
English: In WIMD 2014, there are 1847 LSOAs with unchanged boundaries since WIMD 2011, 61 LSOAs with boundaries resulting from a merge with or split from an adjacent LSOA, and 12 LSOAs with boundaries resulting from more complex changes.
Welsh: Yn MALlC 2014, roedd 1,846 AGEHI na newiddiodd ffiniau ers MALlC 2011, 61 AGEHI gyda ffiniau oedd yn ganlyniad i uniad neu raniad o AGEHI gyfagos a 12 AGEHI gyda ffiniau a grewyd o newidiadau mwy cymhleth.
English: A summary of LSOA boundary changes is provided in the table below.
Welsh: Rhoddir crynodeb o'r newidiadau ffiniau AGEHI yn y tabl isod.
English: M = merge, S = split, X = complex change

English: Children can be disapplied from following the National Curriculum, mainly as a result of them having a statement of special educational needs prepared by their LEA.
Welsh: Mae modd datgymhwyso plant o'r Cwricwlwm Cenedlaethol, yn bennaf oherwydd bod ganddynt ddatganiad anghenion addysgol arbennig gan yr AALl.
English: Children can also be temporarily disapplied if they have recently arrived from a different educational system, had spells in hospital, been educated from school or been excluded.
Welsh: Mae modd hefyd datgymhwyso plant dros dro os ydynt yn ddiweddar wedi ymuno o fod yn astudio system addysg wahanol, wedi treulio cyfnod yn yr ysbyty, wedi bod yn cael eu haddysgu gartref neu wedi'u gwahardd.
English: Children can be disapplied from any or all subjects.
Welsh: Mae modd datgymhwyso plant o astudio pob pwnc neu rai yn unig.
English: Average point scores for pupils are assessed by teachers in Year 6 (final year of primary school).
Welsh: Caiff sgoriau pwyntiau cyfartalog disgyblion eu hasesu gan athrawon ym Mlwyddyn 6 (blwyddyn olaf yn yr ysgol gynradd).
English: Because not all children are assessed in Welsh as a first language at Key Stages 2 and 3, the highest score in English and Welsh was taken along with the score in Mathematics and Science, to provide comparability across Wales.
Welsh: Gan nad yw pob plentyn yn cael ei asesu yn Gymraeg fel ei iaith gyntaf yng Nghyfnod Allweddol 2 a 3, defnyddiwyd y sgôr uchaf ar gyfer Cymraeg a Saesneg ynghyd â'r sgôr Mathemateg a Gwyddoniaeth er mwyn gallu cymharu dros Gymru.

Welsh: Dywedir bod gan annedd berygl Categori 1 o ganlyniad i oerni gormodol os oes bygythiad difrifol o dymheredd is na'r hyn sy'n dderbyniol dan do.
English: A dwelling is assessed as having a Category 1 hazard in terms of falls if there is determined to be a serious risk of falling on stairs, between levels, level surfaces or falling associated with a bath, shower or similar facility.
Welsh: Dywedir bod gan annedd berygl Categori 1 o ran cwympo os credir bod perygl difrifol o gwympo ar y grisiau, rhwng lefelau, ar arwynebedd gwastad neu gwympo mewn bath, cawod neu gyfleuster tebyg.

English: About this release
Welsh: Am y datganiad hwn
English: This release is one of four statistical outputs providing statistics for Wales and each of the three regions as defined in the Economic Action Plan, for nine key themes.
Welsh: Mae'r datganiad hwn yn un o bedwar allbwn ystadegol sy'n rhoi ystadegau ar gyfer Cymru a phob un o'r tri rhanbarth, fel y'u diffinnir yn y Cynllun Gweithredu Economaidd, ar gyfer naw thema allweddol.
English: Together these releases have been prepared to inform regional planning, supporting the National Infrastructure Commission for Wales, the National Development Framework and the Economic Action Plan.
Welsh: Gyda'i gilydd, mae'r datganiadau hyn wedi cael eu paratoi i roi gwybodaeth ar gyfer cynllunio rhanbarthol, gan gefnogi Comisiwn Seilwaith Cenedlaethol Cymru, y Fframwaith Datblygu Cenedlaethol a'r Cynllun Gweithredu ar yr Economi.

English: Statistical data is used widely to support regional planning across Wales.
Welsh: Defnyddir data ystadegol yn eang i gefnogi cynllunio rhanbarthol ar draws Cymru.
English: This series of releases brings together in one place key data on the economy, population and infrastructure in Wales to meet user needs for data on the three Welsh economic regions (North Wales, Mid and South West Wales, and South East Wales).
Welsh: Mae'r gyfres hon o ddatganiadau yn dod â data allweddol am economi, poblogaeth a seilwaith Cymru ynghyd i fodloni anghenion defnyddwyr data ar dair rhanbarth economaidd Cymru (y Gogledd, y Canolbarth a'r De-orllewin, a'r De-ddwyrain).
English: The aim of this release is to provide context to the individual regional releases and to highlight differences that exist between the three regions for the nine topics in question.
Welsh: Nod y datganiad hwn yw rhoi cyd-destun i'r datganiadau rhanbarthol a thynnu sylw at wahaniaethau sy'n bodoli rhwng y tri rhanbarth ar gyfer y pynciau dan sylw.
English: Although this release is split into chapters, it is important to remember that there is interaction between the various topics and when using the information for planning the data should be put into context.
Welsh: Er bod y datganiad hwn wedi'i rannu'n benodau, mae'n bwysig cofio bod yr amrywiol bynciau yn effeithio ar ei gilydd ac wrth ddefnyddio'r wybodaeth ar gyfer cynllunio dylid rhoi'r data mewn cyd-destun.
English: Differences between parts of Wales can often be down to the demographic or socio-economic characteristics of a region.
Welsh: Gall gwahaniaethau rhwng rhannau o Gymru yn aml fod yn sgil nodweddion demograffig neu economaidd-gymdeithasol y rhanbarth.
English: For example, levels of economic activity are influenced more by qualification levels than where a person lives.
Welsh: Er enghraifft, mae lefelau gweithgarwch economaidd yn cael eu dylanwadu llawer yn fwy gan gymwysterau na'r ardal lle mae person yn byw.
English: An older, less economically active, population in an area will influence levels of economic output per head.
Welsh: Bydd poblogaeth hŷn, llai gweithgar yn economaidd mewn ardal yn dylanwadu ar lefelau allbwn economaidd y pen.
English: Demographic trends vary across Wales in terms of age distribution and natural change, leading to differences in future population and housing trends across and within the regions.
Welsh: Mae tueddiadau demograffig yn amrywio ar draws Cymru o ran dosbarthiad oedran a newid naturiol, gan arwain at wahaniaethau mewn tueddiadau poblogaeth a thai yn y dyfodol ar draws ac o fewn y rhanbarthau.
English: Geographical context is also important, for example in considering data on infrastructure, either physical or digital.
Welsh: Mae cyd-destun daearyddol hefyd yn bwysig, er enghraifft wrth ystyried data ar seilwaith, boed yn gorfforol neu ddigidol.
English: The interconnectedness with the rest of the UK means our economic performance is closely linked to UK and global trends, and in many border areas commuting levels will impact on some measures of economic output.
Welsh: Mae'r cydgysylltiad â gweddill y DU yn golygu bod cysylltiad agos rhwng ein perfformiad economaidd a thueddiadau'r DU a byd-eang, ac mewn nifer o ardaloedd ffiniol bydd lefelau cymudo yn effeithio ar rai mesurau allbwn economaidd.

Welsh: Gellir priodoli hyn i raddau helaeth i Gaerdydd, sef yr awdurdod mwyaf poblog yng Nghymru gyda 2,574.6 o bobl fesul cilomedr sgwâr.
English: The region also saw the most growth in population density over the last decade, up 5.4 per cent on 2007.
Welsh: Yn y rhanbarth hwn hefyd y gwelwyd y cynnydd mwyaf yn nwysedd y boblogaeth dros y degawd diwethaf, sef 5.4 y cant o gymharu â 2007.
English: Population density (persons per square kilometre) by local authority and year
Welsh: Dwysedd y boblogaeth (unigolion fesul cilomedr sgwâr) yn ôl awdurdod lleol a blwyddyn
