From the Summary: "The economic contraction that began in February 2020 differs from previous contractions, including the Great Depression of the 1930s and the Great Recession of 2007-2009. It was caused in large part by concerns about the spread of the Coronavirus Disease 2019 (COVID-19) and government policies aimed at limiting person-to-person contact. The health concerns of the public and the stay-at-home and shutdown orders designed to limit contact reduced cash flow to businesses and increased the number of unemployed workers."
