Welsh Index of Multiple Deprivation - Indicator data

Bookmark and Share
  • Release date: 2 August 2018
  • Period covered: Various
The Welsh Index of Multiple Deprivation (WIMD) is updated every few years. However, a selection of indicators that feed into the index are updated in between full WIMD updates.

Revision to low birth weight indicator data

In August 2018 a revision was made to 2017 low birth weight data due to an error in the source data originally provided to us by a third party. This revision has led to a reduction in the percentage of low birth weights for some areas in the 2017 data. Following the revision the all Wales figure has reduced from 6.1 per cent of births having a low weight to 5.5 per cent of births having a low weight.

WIMD annual indicator data updates – suspended for 2018

Due to changes in underlying data sources and time needed to develop WIMD 2019, there will be no update to WIMD indicators during 2018.

Four of the nine indicators normally updated are affected by changes in the underlying data. The other five are multi-year averages unlikely to change significantly in a year, or unlikely to have a significant impact if not updated during 2018.

We plan to publish a consultation during autumn 2018 on proposed indicators for WIMD 2019, and are currently working with a range of experts and users of the data to develop our proposals. Plans for annual updates to some of the indicator data following 2019 will be included in our consultation proposals.

For more details see the note on WIMD indicators – suspended for 2018 (PDF 166KB).

The latest indicator data

Between December 2017 and January 2018 the following WIMD indicators were updated:

  • Percentage of people in income deprivation (based on people claiming an income related benefits, supported asylum seekers and dependent children of income deprived people). This data is available by age group.
  • Percentage of working-age people in employment deprivation (based on employment-related benefits including Universal Credit). This data is available by age group.
  • Rate of deaths per 100,000 people (standardised for the age and sex profile of the population).
  • Rate of cancer incidences per 100,000 people (standardised for the age and sex profile of the population).
  • Percentage of births of single babies (i.e. not twins or triplets etc) with a birth weight of less than 2.5 kg (5.5 lbs).
  • Fire incidences: number of fires per 100 people.
  • Key Stage 2 Average Point Score: Average scores for pupils assessed by teachers in Year 6 (final year of primary school).
  • Key Stage 4 Level 2 inclusive: Percentage of pupils achieving the equivalent of 5 A* to C grade GCSEs.
  • Key Stage 4 Capped Point Score: Average point score per pupil for all qualifications achieved up to the equivalent of 8 GCSEs.
  • Repeat absenteeism rate: the percentage of pupils missing 15 per cent or more of school sessions. This data is available for all pupils, primary school pupils and secondary school pupils.
All of these indicators have been updated at Lower-layer Super Output Area (LSOA) level. LSOAs are defined by the 2011 Census as small areas with a population between 1,000 and 3,000 people. The indicator data at LSOA level can be downloaded as a csv file (CSV, 170KB) or viewed/downloaded from the StatsWales website.

The indicators have also been updated for several different larger geography groups, including:

  • Middle-layer Super Output Areas (MSOAs) – as defined by the 2011 Census
  • Local Authorities
  • Community First clusters
  • Strategic Regeneration Areas
  • Built Up Areas
  • Rural/Urban classification
  • Rural/Urban classification in each Local Authority

The data for these larger geography groups can be found on the StatsWales website.
