It's obviously not an exact science, since "middle class" has as much to do with how people define their own social status as it has to do with their actual income. But those measures counting hundreds of millions of Indians as middle class are doing that by including people surviving on a few dollars a day. Maybe in an Indian context where poverty is widespread this is considered middle class, but it's quite misleading to present that as middle class to a Western audience.

I'm willing to bet that the disposable income of the US/EU middle classes exceeds that of the Indian one at least 10:1, for now.
