The U.S. Cluster Mapping Project is a national economic initiative that provides open, interactive data to understand regional clusters and support business, innovation, and policy in the United States. It is based at the Institute for Strategy and Competitiveness at Harvard Business School, with support from a number of partners and a federal grant from the U.S. Department of Commerce's Economic Development Administration. The Project provides a robust cluster mapping database grounded in the leading academic research. Professor Michael Porter pioneered the comprehensive mapping of clusters in the U.S. economy in the early 2000s. The research team from Harvard Business School, MIT Sloan, and Temple Fox School of Business used the latest Census and industry data to develop an algorithm that defines cluster categories covering the entire U.S. economy, which standardize clusters and enable comparative analyses between any region in the United States.
