English Indices of Deprivation (IoD): Calderdale

IoD measure several dimensions of neighbourhood deprivation. This is done at Lower level super output area (LSOA) level across England. A LSOA has between 1,000 and 23,000 residents (between 400 and 1,200 households). The IoD is updated every four to six years.

This dashboard contains the data for the last three editions of IoD: 2025, 2019 and 2015. Each page of the dashboard contains a Page note button which provides information on how to use the page.

IoD is split into seven domains, three of which have two sub domains each, two supplementary indices and one overall index called the Index of Multiple Deprivation (IMD). These are listed on the front page of the dashboard, and also further down this page: Domains, sub domains and supplementary indices.

Domains, sub domains and supplementary indices

There are seven domains: These are combined using weights to create the Index of Multiple Deprivation (IMD).

Income deprivation (22.5%) | Employment deprivation (22.5%) | Education, skills and training deprivation (13.5%)* | Health deprivation and disability (13.5%) | Crime (9.3%) | Barriers to housing and services (9.3%)* | Living environment deprivation (9.3%)*. The two supplementary indices are Income deprivation affecting children index (IDACI) and Income deprivation affecting older people index (IDAOPI).

* The domains marked with a star in the above list include two sub domains each. Education, skills and training deprivation sub domains are Children and young people and Adult skills. Barriers to housing and services sub domains are Geographic barriers and Wider barriers. Living environment deprivation sub domains are Indoors and Outdoors.
