Understanding each statement.
(A) is correct: The Human Poverty Index (HPI) is specifically designed to measure deprivations in three basic dimensions: longevity, knowledge, and standard of living. Unlike the Human Development Index (HDI), which is an aggregate measure of a country's development based on the same dimensions, HPI focuses on the population's deprivation in these key areas.
(B) is correct: The HDI is a composite index measuring human development through life expectancy, education, and standard of living. However, it does not adjust for inequality within a country. The Inequality-adjusted Human Development Index (IHDI) accounts for inequality in the distribution of these dimensions, but the basic HDI does not.
(C) is incorrect: Income-based poverty lines are not enough to measure well-being comprehensively. They fail to capture essential dimensions such as education and healthcare, which are key aspects of a person's well-being. Hence, using only income to measure poverty provides a limited view of the population’s welfare.
(D) is incorrect: The Multidimensional Poverty Index (MPI) does not specifically account for intra-household distribution of resources. The MPI measures poverty through dimensions like education, health, and standard of living, but it does not directly assess how resources are distributed within households.
