2020 Census: Update on the Census Bureau's Implementation of Partnership and Outreach Activities, Report to Congressional Requesters [open pdf - 2MB]
From the GAO [Government Accountability Office] Highlights: "The decennial census is used to apportion seats in Congress, redraw congressional districts, and allocate hundreds of billions of dollars in federal assistance annually and helps to guide public policy decisions based on social, economic, and demographic data. While recent censuses appear to have been increasingly accurate, measurement errors are not evenly distributed across the population. Given the uses of census data, ensuring an accurate count is important. As part of its partnership and outreach efforts, the U.S. Census Bureau's (Bureau) Partnership Program works with local and national organizations, businesses, and governments to promote awareness of and participation in the census, as well as to help recruit census workers. GAO was asked to review the Bureau's partnership and outreach efforts, including paid advertising and targeted communications. This report examines the Bureau's progress in addressing selected prior census challenges in these areas. GAO reviewed relevant Bureau planning documentation, collected regular Bureau reports on progress, and interviewed Bureau officials responsible for partnership and outreach efforts."
