Firstly, since you are comparing the data for both India and BD, i'm assuming that you will be able to appreciate the relevance of Purchasing Power Parity. Now for India, renowned economists from India's leading JNU have pegged the PPP rate at - 1 USD=Rs. 19.
So given that the internationally accepted line stands at USD 1.25 per day, basic math will tell you that India has drawn a poverty line that is comfortably clear of the World Bank's poverty line.
Hence, I see little room for silly arguments about "tweaking" and "adjusting" numbers, based on a casual read of sensational headlines.
Secondly, India is a poor country - there's no denying that. But, you guys ridicule India, as if to suggest that BD has been able to ape the chinese model for addressing poverty. It is warranted for your chinese masters to act with such disdain, because they have actions / achievements to back their tall talk - not you guys!!
Your government tells you that 31% of population is below the poverty line. Now keep in mind, that you are busy selling me the same govt's data - that you claim has "sold out" to foreign forces.
Leaving the subject of credibility of your govt aside, scholars from your own country have a very different opinion. Some have recently argued that "real poverty rate" could be higher that 66%". Here's a link.

Meanwhile, the comprehensive Multidimensional Poverty Index also paints a grim picture. As per the findings of the index the "incidence of poverty" in BD is as high as 57.8%. For india, the figure stands at 55.4%. Also, needless to mention, other than a superior ranking on the HDI index, the UNDP index categorises india alongside countries which have provided "medium human development" for their citizens. BD, and even its former master - pak, make up the bottom most layer of the pyramid with countries that have only managed "LOW human development". And this is as per the 2011 rankings.

Stop embarrassing yourself. You guys are small. Too small to matter. Just for some perspective, Reliance Industries, ALONE, in 2017 will have a market cap as big as your country's GDP.
