Lloyd grew up in Delran which is in Burlington county and across the Delaware river from Philadelphia. She attended the local HS. I believe that in general the town would be considered middle class but not "affluent".
Carli is not from a wealthy neighborhood by any stretch. Heath and Press are the two I know grew up in a very privileged and wealthy environment. Crystal Dunn is from Rockville Centre, which has upper middle and more middle class patches... so I'm not sure of her background.
