You need at least a third of the criteria to be true in order for a household to be considered in poverty.
In the United States (where it is not only possible, but common for two people with education to lift a family out of poverty into the middle class), most people below the poverty have a drastically superior standard of living to anyone below the poverty line in India. The type of "poor" where two people are working full time jobs in the US would not be considered poor in India.
