"The U.S. Cluster Mapping Project is used by governments, economic developers, and businesses to understand and shape the competitive landscape for a wide range of industries. These data are being put in the hands of local officials, who are using the information to make strategic investments, recruit new companies, and lay the groundwork for new industries. Across the country, our cluster mapping tool gives us the ability to reinvent and modernize economic development strategies – all driven by open data."
