With reference to poverty measurement methodologies, consider the following statements: I. The headcount ratio measures the proportion of the population whose income or consumption falls below a specified poverty line, but it does not capture the depth of poverty. II. In the multidimensional poverty framework, intensity refers to the average proportion of weighted deprivations experienced by the poor. III. An increase in the headcount ratio necessarily implies an increase in the intensity of poverty. IV. In the Alkire-Foster method, overall poverty is computed as the product of incidence and intensity. How many of the above statements are correct?
