From tribal lands in Arizona and New Mexico to storm-battered Louisiana, census workers who go door to door were unable to reach all the households they needed for a complete tally of the U.S. population, a count that ended abruptly last week after a Supreme Court ruling.
Community activists, statisticians and civil rights groups say racial and ethnic minorities are historically undercounted, and shortcomings in the 2020 census could set the course of life in their communities for years to come.
The count determines the number of congressional seats each state gets, where roads and bridges are built, how schools and health care facilities are funded, and how $1.5 trillion in federal resources are allocated annually.
“An undercount in our community means schools are overcrowded, hospitals are overcrowded, roads are congested,” said John Yang, president and executive director of Asian Americans Advancing Justice.
The census ended last week after the Supreme Court sided with President Donald Trump’s administration and suspended a lower court order allowing the head count to continue through Oct. 31.
The U.S. Census Bureau says that overall, it reached more than 99.9% of the nation’s households, but in a nation of 330 million people, the remaining .1% represents hundreds of thousands of uncounted residents. And in small cities, even handfuls of undercounted residents can make a big difference in the resources the communities receive and the power they wield.
Also, a high percentage of households reached does not necessarily translate to an accurate count: The data’s quality depends on how it was obtained. The most accurate information comes from people who “self-respond” to the census questionnaire online, by phone or mail. Census officials say 67% of the people counted in the 2020 census responded that way.
In any case, census takers, who go door to door, fell short of the 99.9% benchmark in many pockets of the country.
In areas that were not counted, Census Bureau officials said they will use a statistical technique called imputation, which uses the characteristics and size of neighboring households to fill in the gaps of homes with missing data.
Groups suing the administration over the timetables said the deadline for turning in apportionment numbers was moved up to accommodate an order from Trump to exclude people in the U.S. illegally from the numbers used to divvy up congressional seats among the states. Sticking to a Dec. 31 deadline ensures that data processing remains under the administration’s control, regardless of who wins the presidential election.
A panel of federal judges in New York ruled that Trump’s order was unlawful, but the administration has appealed to the Supreme Court. A second panel of federal judges in California on Thursday ruled that the order was also unconstitutional.
“This census isn’t over,” Morial said. “We will continue to fight in the courts, Congress and the court of public opinion.”
