More children ages 1 to 4 die of drowning than any other cause of death. Nearly a quarter of adults received mental health treatment in 2023, an increase of 3.4 million from the prior year. The number of migrants from Mexico and northern Central American countries stopped by the U.S. Border Patrol was surpassed in 2022 by the number of migrants from other nations.

We know these things because the federal government collects, organizes and shares the data behind them. Every year, year after year, workers in agencies that many of us have never heard of have been amassing the statistics that undergird decision-making at all levels of government and inform the judgments of business leaders, school administrators and medical providers nationwide.

The survival of that data is now in doubt, as a result of the Department of Government Efficiency’s comprehensive assault on the federal bureaucracy.

The department’s Administration for Children and Families is weeks behind on the annual update of the Adoption and Foster Care Analysis and Reporting System, the nationwide database of child welfare cases, after layoffs effectively wiped out the team that compiles that information.
