Consider this: According to US government guidelines, as of 2005, an individual with an annual income of less than $10,160 or a family of two with annual income of less than $13,078 is considered to be below poverty line.
That translates to about Rs 37,600 per month for an individual, which in India would be considered being in the upper-income bracket.
The Indian measure for determining poverty is absolutist. Official estimates of the poverty line are based on a norm of 2,400 calories per capita per day for rural areas and 2,100 per capita per day for urban areas. Translating it as money for food, it comes to around Rs 600 per month, as of 2005.
So technically, anyone earning more than Rs 600 is considered above poverty line. Yet, 28% of India's population is considered below poverty line.
