Commerce Department bans Census Bureau and BEA from using noise infusion in published statistical products

The Commerce Department ordered the Census Bureau and Bureau of Economic Analysis to stop using noise infusion, a privacy technique that adds random variation to published statistics. The article explains how such methods help protect confidential source data, including census responses, while still allowing agencies to release useful aggregate numbers.

The ban could reshape federal statistical privacy practices by limiting a key tool used in differential privacy, widely viewed by researchers as a strong standard for disclosure avoidance. It reflects growing tension between data accuracy, public trust, and modern privacy protections as government datasets become easier to cross-reference and re-identify.
