The Index of Economic Resources (IER) focuses on the financial aspects of relative socio-economic advantage and disadvantage, by summarising variables related to income and wealth. This index excludes education and occupation variables because they are not direct measures of economic resources. It also misses some assets such as savings or equities which, although relevant, could not be included because this information was not collected in the 2011 Census.
Interpretation of Index Scores (IER)
A low score indicates a relative lack of access to economic resources in general. For example, an area may have a low score if there are:
- many households with low income, or many households paying low rent
- few households with high income, or few owned homes
A high score indicates relatively greater access to economic resources in general. For example, an area may have a high score if there are:
- many households with high income, or many owned homes
- few low income households, or few households paying low rent
This index is preferred in situations where the user:
- is looking specifically at access to economic resources.
An example would be where a user:
- is interested in wealth as well as income for analysis.
We do not recommend using this index if the user:
- is only interested in disadvantage, as this index measures both advantage and disadvantage
- is interested in more general advantage and disadvantage, such as the IRSAD
- is also analysing information that was included in the index, such as household income.
The variables that are included in the index can be found below. Each variable has a loading that indicates the correlation of that variable with the index. A positive loading indicates an advantaging variable where as a negative loading indicates a disadvantaging variable.
FINAL VARIABLES LIST
Note - The loadings are closely related to the variable weights used in the construction of the index. For details, please refer to Chapter 4.1 in the Technical Paper.
The table below shows variables that were initially considered for the index, but were subsequently dropped (excluded) due to low loadings (not adding enough value to the final index). For more information, please refer to Chapter 4.3 in the Technical Paper.
