American Society of Planning Officials

The American Society of Planning Officials (ASPO) was a professional organization founded in 1934 to support urban and regional planning professionals. It aimed to promote high standards in planning practice, education, and policy development. ASPO provided a platform for sharing knowledge, advancing planning techniques, and advocating for well-designed, sustainable communities. In 1979, it merged with the American Institute of Planners to form the American Planning Association (APA), which continues to serve planners today. Overall, ASPO played a key role in shaping the professional field of urban planning in the United States.
