The local authority with the highest proportion of small areas in the most deprived 10% in Wales for
access to services was Powys (50.6%, or 40 areas). Ceredigion was the next highest, with 50% (or
23) of its areas in the most deprived 10%. This is because these local authorities are large and
sparsely populated, with many small rural settlements.
Neath Port Talbot, Bridgend, Rhondda Cynon Taf, Blaenau Gwent, Torfaen, and Cardiff local
authorities had no small areas in the most deprived 10%. However the local authority with the
fewest areas that were among the most deprived 50% in Wales was Caerphilly (26.4% or 29 areas).
Powys and Ceredigion had just under 90% of their small areas in the most deprived 50% in Wales,
followed by Gwynedd and Pembrokeshire, with around three-quarters of their areas in the most
deprived half of Wales.
7.6. Access to Services domain methodological changes between WIMD 2014 and
WIMD 2019
As well as updating the WIMD 2014 suite of indicators measuring travel times to key services, we
have introduced a new indicator on access to digital services, weighted as 10% within the domain.
This indicator is calculated as the proportion of homes and small businesses unable to receive fixed
line broadband at a download sync speed of at least 30Mb/s (superfast broadband). This includes
properties with no broadband coverage.
Concerning calculation of updated travel times to key services, whilst the principles of methodology
have not changed between WIMD 2014 and WIMD 2019 – the technical toolkits used have
undergone rigorous change to seek to increase the accuracy, robustness and repeatability of the
data. These changes included:
Improvements to granularity of private routing, providing mapping to the doorstep of every
residential address.
Improvements to granularity of public transport routing, changing from a gridded catchment
approach in WIMD 2014 to that of an isochrone approach in WIMD 2019.
Improvements to the definition of residential dwelling to be as encompassing to the
population of Wales as possible, by using domestic council tax records.
Types of services modelled remain unchanged from WIMD 2014, and as such, data sources, the
number of sites and the definitions adhered to are mostly comparable. However, the Food shops
indicator has been enhanced to include certain chains of Frozen Food retailers who adhere to our
basic provisions definition. Leisure Centres have been renamed to Sports Facilities to encompass
the wider service offering now modelled.
Due to the above, care should be taken in interpreting changes in the travel time indicator values,
which are not strictly comparable to older data. The main effect of the update is to raise the lower
