Actually, there is strong feeling in at least in North India, that Kerala is where whole India should be. I am from Haryana and though Haryana is much more developed economically than Kerala, all my friends agree that Kerala is much better.
And when comparing to Bihar, the state is way ahead. At least the statistics show that.
Kerala has the cleanest railway stations, the best sex ratio, the most literate population, second least malnutrition (after Punjab).
