Answer:
The typical method for getting a headcount of impoverished people within a single nation is using a calculated number called an absolute threshold. Typically referred to as a 'poverty line', this threshold indicates that those whose incomes fail to meet a certain standard are poor.
Explanation:
Income method: In this method, there is a certain minimum income. If the personal income goes below this level then he'her considered below the poverty line and it is assumed that his income is not enough to fulfill the basic needs.
Consumption method: A minimum nutritional food requirement is measured and energy obtained from this food is measured in calories. If the calories requirement is not fulfilled then the person is considered to be below the poverty line.
Expenditure methods: In this method, the poverty line is estimated by using the expenditure of the person as a minimum level of food requirement, clothing, footwear, etc.
