I feel seperation has been better for Bihar. Literacy in Bihar increased by 17% from 2001-2011, while it was only 14% for jharkhand, at this rate bihar's literacy will be higher than jharkhand till next census. Bihar averages growth of 10.5% in last 10 years, jharkhand is low down in the list.
Jharkhand is doing better after seperation, LOL, wake up from dreams
