What is the IDACI? 

The income deprivation affecting children index (IDACI) measures the proportion of all children aged 0 to 15 living in income deprived families in different local areas (called 'lower-layer super output areas', or LSOAs) across England. Each LSOA has on average 1,500 residents or 650 households. 

LSOAs are ranked according to their levels of deprivation relative to that of other areas. The rankings are divided into 7 'bands' (A to G), with LSOAs in band A being the most deprived (read more about the different bands below).

The IDACI is a subset of the index of multiple deprivation (IMD)

While the IDACI focuses on children under 16, the IMD measures the overall relative measure of deprivation across the LSOAs.

They measure deprivation based on 7 'domains': 

• Income deprivation
• Employment deprivation
• Education, skills and training deprivation
• Health deprivation and disability
• Crime
• Barriers to housing and services
• Living environment deprivation
