(LOS ANGELES) — A federal judge in California has ordered the Trump administration to continue its 2020 Census count through Oct. 31, overriding the administration’s efforts to shorten the timeline to submit results.

Census Bureau officials and experts said they need more time to accurately count everyone living in the country given the unprecedented challenge of the COVID-19 pandemic. The information collected as part of the Census every 10 years is used to distribute federal money for schools, health care programs and housing assistance as well as determine House representation.

On Sept. 4, Judge Lucy Koh ordered the Department of Commerce, which oversees the Census Bureau, not to prematurely end counting in September. The Commerce Department had said the count would stop on Oct. 5 and Census employees from around the country contacted the court saying they were being told to wrap up their work.

Koh said those decisions violated her earlier order.

“Defendants’ dissemination of erroneous information; lurching from one hasty, unexplained plan to the next; and unlawful sacrifices of completeness and accuracy of the 2020 Census are upending the status quo, violating the Injunction Order, and undermining the credibility of the Census Bureau and the 2020 Census. This must stop,” she said.

Koh’s order means Census employees will report analysis of the data on April 30, 2021, and not the statutory deadline of Dec. 31.

Koh said the Census Bureau must text all employees on Friday to clarify that their work will continue past Oct. 5. Census Bureau Director Steven Dillingham will also have to submit a declaration detailing how the agency is complying with the order.

Trump administration lawyers have argued that Census workers won’t have enough time to analyze the data if counting extends past Oct. 5.

The later timeline gives control of Census data to the next administration. President Donald Trump has said he wants to exclude undocumented immigrants from the official count, though that order has so far been blocked in the courts.

The federal lawsuit was brought by the National Urban League and other civil rights groups and cities like Los Angeles and Chicago that argued shortening the timeline hurts the American public, especially disadvantaged communities that are historically undercounted. An alert from the Commerce Department’s internal watchdog recently warned that the decision to shorten those timelines was made over the objections of Census Bureau officials and undermines the accuracy of the final count.

As of Sept. 30, 98.9% of households in the country have been counted, according to Census Bureau data, with some of the lowest response rates in Alabama and Louisiana, both states that were impacted by Hurricane Laura. Individuals can still submit a response and, per the judge’s order, workers will continue trying to contact people or estimating populations in places like shelters and group homes.

The next hearing in the case is scheduled on Tuesday.
