Description
|
Conceptually, the purpose of the housing domain is to identify inadequate housing, in terms of physical and living conditions and availability. Here, living condition means the suitability of the housing for its inhabitant(s), for example in terms of health and safety, and necessary adaptations.
The domain has a relative weight of 7% in the overall index. This has increased from 5% in the 2014 index, due to the addition of a new modelled indicator on the likelihood of poor quality housing.
The income domain is made up of two equally weighted indicators:
- An indicator on overcrowding measures the percentage of people living in overcrowded households (2011 Census-based bedroom measure).
- A new modelled indicator on poor quality housing. It measures the likelihood of housing being in disrepair or containing serious hazards (for example, risk of falls or cold housing), and was calculated from a mixture of survey and administrative data sources by the Building Research Establishment (BRE).
For the two indicators, each LSOA was ranked in order, with the most deprived LSOA ranked 1 and the least deprived LSOA ranked 1,909. These ranks were assigned to a normal distribution (with low ranks receiving a low normalised value) before being combined with equal weighting. As with all domains, the final domain ranks were exponentially transformed, to form domain scores for use in the calculation of the overall WIMD 2019. |
