“A report from Commerce Department’s Office of Inspector General in September found that the decision to accelerate the census schedule “was not made by the Census Bureau” and that it “increases the risks to obtaining a complete and accurate 2020 Census.”
“Senior career officials at the Bureau perceived that this decision resulted from the Administration no longer supporting the schedule extension, but ultimately they lacked visibility into this decision process,” the report read. “Bureau leaders continued to believe that the statutory extension was preferable, and would give the Bureau the best chance to create a high-quality, usable census.””
