¶As reported by the practice champion.
**The Income Deprivation Affecting Children Index measures the proportion of all children aged 0–15 living in income deprived families. It is a subset of the Income Deprivation Domain which measures the proportion of the population in an area experiencing deprivation relating to low income. The definition of low income used includes both those that are out-of-work, and those that are in work but who have low earnings (and satisfy the respective means tests).
