Urban population density An urban density model is a for- mula that relates the population density D (in thousands/ mi?) to the distance x (in miles) from the center of the city. The formula D = ae-bx for the central density a and coeffi- cient of decay b has been found to be appropriate for many large U.S. cities. For the city of Atlanta in 1970, a = 5.5 and b = 0.10. At approximately what distance was the population density 2000 per square mile?
