The pattern is simple... If one city is developed properly and a particular industry is been targetted then you can see a lot of changes thats wat happened in AP... but in UP it wont happen coz even noida is a part of UP as it didnt spread.. if u consider karnataka after bangalore its spreadin to hubli mysore...in gujarat,from ahmedabad to surat,gandhinagar,Maharshtra from mumbai pune nasik but in UP only noida while in bihar nothing.... it doesnt spread and remains stagnant
