The U.S. Bureau of the Census provides an array of free, high-quality data on population, housing, and other information essential to the work of planners. The information is accessible to anyone with an Internet connection, but some insight into how the information is gathered and organized can make it even easier to navigate. This report from APA's Planning Advisory Service provides that insight, as well as a look at the increasingly popular American Community Survey and the upcoming Census 2010. It also provides tools to help planners use the census to document past growth and project future growth.
