Service delivery responsibilities, however, vary widely among counties. For most, construction/maintaining local roads is one of their prime duties. North Carolina counties, however, have no responsibilities in this area. Wide variations also exist in the social service responsibilities and the types of utility services (e.g., water supply) provided by county governments.
