The Quarterly Workforce Indicators (QWI) are published by the LEHD Program at the U.S. Census Bureau. Public use data are available at http://www.vrdc.cornell.edu/qwipu/ (registration required by sending email to virtualrdc@cornell.edu). These data were previously available on the CRADC here at CISER, but support on the CRADC has been discontinued.
