As with economic measures, there are many mixed or non-economic measures of poverty and experts contest which one is most appropriate for India. For example, Dandekar and Rath in 1971 suggested a measure of poverty rate that was based on number of calories consumed. In 2011, Alkire et al. suggested a poverty rate measure so-called Multi-dimensional Poverty Index (MPI), which only puts a 6.25% weight to assets owned by a person and places 33% weight on education and number of years spent in school. These non-economic measures remain controversial and contested as a measure of poverty rate of any nation, including India.
