Proposals may be submitted on a rolling basis. Once approved, researchers become sworn agents of the Census Bureau and work within the BRDC secure facility. Foreign nationals are welcome to participate in the FSRDC program but must have lived in the United States for at least three years. Results intended for circulation in working papers and publications are screened to avoid disclosure of confidential information prior to release from the center. More details can be found here.
The Boston Census Research Data Center (BRDC) is part of the Federal Statistical Research Data Center (FSRDC) program and is operated as a partnership between the U.S. Census Bureau and the National Bureau of Economic Research (NBER). Open since 1994, the BRDC provides qualified researchers the opportunity to perform statistical analysis on non-public microdata from the Census Bureau, National Center for Health Statistics (NCHS), Agency for Healthcare Research and Quality (AHRQ), Bureau of Labor Statistics (BLS), and Bureau of Economic Analysis (BEA).
