I've been doing some research on the Detroit City Budget and the cost per household to provide core city services from 1970 to 2010. The issue I'm having is accounting for Detroit residents' share [[as opposed to the suburbs) of the Water and Sewerage allocation. Any thoughts? Does anyone have access to information on how much of the Water and Sewerage department's budget is spent on the suburbs, particularly 1970, 1980, 1990, 2000, and 2010?
