Population Data

Manhattan has seen large amounts of growth in the past several decades, and the other areas of the Greater Manhattan Area are growing at incredibly fast rates. The population of Pottawatomie County, due in part to the expansion of Manhattan east into Pottawatomie County, has been growing steadily over the past two decades and is one of the fastest growing counties in Kansas. Using information from the University of Kansas Institute of Policy and Social Research, the U.S. Census Bureau, Kansas Statistical Abstract, and Wichita State University's Center for Economic Development and Business, the displays below were created to show current population demographics and projections of the Greater Manhattan Area's future.
