Our latest indicators of local child poverty, published by the End Child Poverty campaign, show an alarming increase in child poverty rates, provide the most robust local estimates of child poverty to date. They build on official data from tax and benefit records, which DWP and HMRC have used to produce local estimates of child poverty. These official figures do not take account of housing costs, underestimating the extent of low disposable income, especially in London and southern England. We have therefore modelled the effect of local housing costs to produce an "after housing cost (AHC)" poverty estimate. This involves using survey data to estimate the correlation between private rent levels and the ratio of AHC to BHC poverty, and applying the result to each local area.
