Like UK in USA, there are some nice areas and there are bad areas. In general, you should avoid living in ghetto or high crime cities. If you are on tight budget then it is not easy to find nice areas.
I personally do not know anything about living in Louisiana State but if you were considering moving to New York, Georgia or West Virginia, I can recommend places. However, you can check the links below to find detailed and current info about the cities you are considering. I hope you can find some nice areas in Louisiana. Good luck
