Experts define poverty in many different ways, they say poverty is connected to national income or the distribution of expenditures where they most focus on the income of a household how much they generate and what good and needs they spent it on. Poverty is the limitations towards basket of goods, this came from the ​poverty datum line which is made of two parts, the primary poverty datum which only included the costs of food, clothes, cleaning supplies, electricity, and light, and the Secondary Poverty Datum Line, which also included the cost of housing, taxation and transportation for breadwinners.

The experts introduced the Household Subsistence Level and Household Effective Level to determine poverty  what expenses and needs do a household must have to be considered living in poverty or not, and this limited the number of poverty by 50% according to (Meth, 2006). 

Hoogeveen and Ozler - Upper and Lower Bound Poverty Lines, use the cost of basic needs to determine poverty which focused on prices, their basket of goods had food, alcohol, cigarettes, lodging and utilities, compensation for domestic employees, personal care, household facilities and other household consumer products, fuel (excluding firewood and dung), clothing and footwear, and transportation (excluding public transportation), purchased cars, communication costs, schooling, reading materials, permits, and other expenses

The food insecurity measures of poverty, it calculated the subsistence diet for households, or it is based on food consumption. This approach suggest that  poor people
standards of living, result of their previous decisions, which are used to determine other needs.
Their poverty and lack of access to capital have dictated that they obtain only what they need or want.

Townsend, 1979. defined poverty as lack of resources to get a good diet, engage in building activities, and must have good surviving conditions and comforting customary that are approved by the society.
