Why the GSS Initiative?Why the GSS Initiative?Recommendations of our stakeholder and oversight communities (GAO, OIG, NAS): Lack of a comprehensive geographic update program between censuses

Associated negative impact on ongoing programs such as the American Community Survey, other current surveys, and

small areas estimates programs

•Addresses to be verified: 145 million •Census workers hired: 140,000 •Hand-held computers: 151,000 •Local Census Offices managing operations: 151 •Operational Dates: March 30 - July 2009
