Poverty is a state or condition in which a person or community lacks the financial resources and essentials for a minimum standard of living. ND indicates that the person is not deprived (in other words, his or her value in that indicatoris equal or higher than the cutoff), and D indicates that the person is deprived (his or her value is lower than the cutoff). Official estimates for global poverty over the course of the Coronavirus pandemic are not yet available. Global poverty data relies on national household surveys that have differences affecting their comparability across countries or over time.
