Five hundred households in a middle-class neighborhood were recently surveyed as part of an economic development study conducted by the local government. Specifically, for each of the 500 randomly selected households, the survey requested information on the following variables: family size, approximate location of the household within the neighborhood, an indication of whether those surveyed owned or rented their home, gross annual income of the first household wage earner, gross annual income of the second household wage earner (if applicable), monthly home mortgage or rent payment, average monthly expenditure on utilities, and the total indebtedness (excluding the value of a home mortgage) of the household. The data are in the file P4_4.XLS. Clean all usable data in this set.
