Pierce County's population has tripled in the sixty years since 1950 with Asian American and African American numbers growing rapidly.

 

These maps and tables were created by Anna Yoon, Brian Lam, Gihoon Du, Jiang Wu, and Yurika Harada using data and shape files from the National Historical Geographic Information System (NHGIS).
