The overlap between income poverty and material deprivation: sensitivity evidence for Australia

Many studies have noted the low overlap between income poverty and material deprivation when the latter is derived using the consensual approach that builds on the work of Townsend. However, few have examined the contributing factors and even fewer have assessed the sensitivity of the overlap to different approaches and adjustments. This paper uses Australian data to examine the impact on the overlap of data adjustments and three substantive factors: short-run income fluctuations, housing costs and net wealth. The analysis shows that accounting for two of these factors leads to a marked increase in the overlap between poverty and deprivation.
