To be effective, anti-sprawl efforts must be targeted at the factors that are most responsible for the encroachment of cities and their suburbs on the surrounding rural land. The relative contributions of the factors must be understood if anti-sprawl resources are to be used efficiently and effectively. This website features U.S. government data and analysis of that data that allow the visitor to see the roles of contributing factors in the sprawl of individual urban areas, states, bio-regions and the nation as a whole.
