New development of commercial real estate and of the ongoing operations of existing commercial real estate buildings in the United States – office, industrial, warehouse and retail – supported 8 million American jobs, contributed $1.01 trillion to the U.S. GDP in 2020, and generated $338.1 billion in personal earnings – according to “Economic Impacts of Commercial Real Estate, 2021 U.S. Edition,” a study released this week by the NAIOP Research Foundation.
