Indian Middle Middle Class, who exactly is this ?

This title contains two "middle" , not written out of accident, but i am mentioning about the real center portion of the Gravity point in india.
Read an article on the myth called Indian middle class, and after reading that, lot of questions passed through my mind.


Why the middle class segment in india is ever growing in the last few decades ?
How do you classify if a person is Middle class ?
What is the criteria for sub sections in middle class called, Lower middle class , Middle middle class and upper middle class.
Which class i belongs to ?


The ADB report defines the middle class as those earning between $2 and $20 per person per day, measured in international dollars, ie adjusted for purchasing power parity. The ADB does add further nuance by splitting the middle class into three sub-sections:


lower middle class ($2 - $4), ( approx INR 88 - INR 180)
middle middle ($4 - $10) (Approx INR180 - INR 450 )
and upper middle ($10 - $20). ( Approx INR 450 - INR 900)


The current population of the world is 6.8 billion, while India has a staggering graph of 1.2 billion, a place behind China with 1.3 billion. World's population is expected to reach 9.3 billion mark by 2030 and the ADB's "Key Indicators for Asia and the Pacific 2010" report also mentioned that, in india, by the year 2030, there will be a Billion ( 1 billion) people in this so called middle class. Which means, Indian middle class will be more than 10% of the entire population in the world.


Do you belong to this ever growing Indian middle class ?
