As with many countries, poverty was historically defined and estimated in India using a sustenance food standard. This methodology has been revised. India's current official poverty rates are based on its Planning Commission's data derived from so-called Tendulkar methodology. It defines poverty not in terms of annual income, but in terms of consumption or spending per individual over a certain period for a basket of essential goods. Furthermore, this methodology sets different poverty lines for rural and urban areas. Since 2007, India has set its official threshold at 26 a day ($0.43) in rural areas and about 32 per day ($0.53) in urban areas. While these numbers are lower than the World Bank's $1.25 per day "income"-based definition, the definition is similar to China's US$0.65 per day official poverty line in 2008.
