Abstract:	There has been conflicting empirical evidence of the extent of rural-urban differentials in relative poverty in Nigeria. Measures of inequality based on the Lorenz curve do not provide conclusive evidence or a sound basis for comparison, especially when the Lorenz curves cross one another. The examine rural-urban disparity in relative poverty in Nigeria, the author applies the Gini-Lorenz ratio and the extreme mean disparity index derived by Iyengar and Vani (1986) by assuming that consumption expenditure is lognormally distributed. Both measures show that relative poverty or inequality is higher in urban than rural areas. Bibliogr., sum. [Journal abstract]
