Technically, the brief unsigned order only pauses the population count. The Trump administration is still fighting in a federal appeals court over whether the count can officially be stopped early.
As a practical matter, however, it almost certainly ensures an early end because the census—one of the largest government activities, involving hundreds of thousands of workers—can’t be easily restarted and little time remains before its current deadline at the end of this month.
Occurring every 10 years, the census count is the most thorough tabulation of U.S. residents, collecting information about their demographics and where they live. That information is important because it determines how government funds and political power are allocated over the next decade. It also serves as the basis for how congressional and local voting districts are drawn.
Most experts said a shortened census would worsen existing undercounts of the people who have always been hardest for census workers to reach—minorities who may be intimidated by the questions, and the poor and young people, who move frequently and are more difficult to track down. The effect of undercounting them would be to dilute the power of some of the country’s most populous states, such as California and New York.
