JRC Statistical Audit of the Individual Deprivation Measure

The Individual Deprivation Measure (IDM) is a gender-sensitive, multidimensional measure of poverty. The measure assesses deprivation at the individual level, in relation to 15 key dimensions of life, namely Food, Water, Shelter, Health, Education, Energy/fuel, Sanitation, Relationships, Clothing, Violence, Family planning, Environment, Voice, Time- Use and Work. It offers information additional to other national surveys, providing a high level summary of deprivation through an index while enabling users to gain further understanding through the decomposition and disaggregation of the scalar, gender-sensitive, individual-level data on which it is based. European Commission’s Competence Centre on Composite Indicators and Scoreboards (COIN) at the Joint Research Centre (JRC) was invited by the International Women’s Development Agency (IWDA) to audit the IDM study concerning the Fiji (2014-17) dataset. In this dataset, composed by almost three thousands subjects, only 13 out of 15 key dimensions of the IDM are considered. The statistical audit presented herein aims to contribute to ensuring the transparency of the IDM methodology and the reliability of the results. The report touches upon data quality issues, the conceptual and statistical coherence of the framework and the impact of modelling assumptions on the results.
