Getting Around Sac — Our writer consulted with Aaron Golub at Portland State University on how to incorporate demographic data into proposals. He suggested EJScreen, which has been very helpful as it is user friendly. To get a basic feel for demographics of an area, Marisa uses American FactFinder. At the Alta Portland office, we also have an incredible GIS team and they are a great mapping resource. Hope this helps you incorporate demographic data into your proposals!
