“Delays, the resulting compressed timeframes, implementation of untested procedures, and continuing challenges such as COVID-19 could escalate census costs and undermine the overall quality of the count,” the agency wrote.
CNN has reached out to the Census Bureau for comment.
A coalition led by the National Urban League asked a federal judge on Tuesday to act promptly and extend the 2020 census response deadline, accusing the Trump administration in a lawsuit last week of illegally and unconstitutionally compressing the time the Census Bureau has to follow up with households that do not respond to the census survey.
Chris Mihm, managing director of strategic issues at GAO who helped lead work on the report, told CNN that the Bureau’s decision to end data collection one month earlier than planned “reduces the amount of time the Bureau has to follow-up on about 56 million households that did not initially respond to the census,” noting that “late design changes such as this with compressed timeframes, pose a risk to a complete and accurate count.”
Thursday’s report referenced potential issues with the Bureau’s nonresponse follow-up operation, noting that due to its complexity, “significant risks remain regarding how the systems will perform.”
“For example, if any aspect of the technical innovations— including the systems that support those innovations—do not perform as expected, the Bureau may incur significant costs to troubleshoot and resolve systems issues that arise,” the report continues. “In addition, if (nonresponse follow-up) systems do not perform as expected, the Bureau may miss scheduled milestones for completing the operation.”
The report also highlighted that while “the Bureau has implemented 90 of our recommendations,” as of this month, “21 of the recommendations have not been fully implemented and 10 of these are designated as priority recommendations.”
