You are the one who doesn't get it. If you throw numbers around, then India will be bigger every time. We have the bigger GDP, bigger army, we have more rich, we have more poor, we have more births, we have more deaths, and so on. So it's obvious we will have more poor also. If our biggest state in terms of population, that's bigger than Pakistan, suddenly vanishes, poof, even then India's population will still be more than 1 billion. I don't think understand India's size.
In terms of percentages, India beats Pakistan in every way, including poverty.
India's poverty standards are also higher than what WB proposes. They ask for $1.9, we use $2 for rural and $3 for urban citizens.
