What is the absolute poverty line used by the World Bank?

A poverty line is a threshold used to set the minimum level of income a household or individual must have in order to meet their basic needs. It is often used to distinguish between those who are in poverty and those who are not. The absolute poverty line used by the World Bank is a measure of poverty set by the World Bank, which is estimated to signify the most basic level of resources needed for basic subsistence. This line is based on the food, clothing and shelter costs associated with living a bare minimum lifestyle, setting a stricter threshold than other more generous measures. It is commonly used in development policies and global initiatives to measure poverty and set goals for poverty eradication.
