Commerce Secretary Raimondo defends census privacy method

By MIKE SCHNEIDER Associated Press Commerce Secretary Gina Raimondo on Wednesday defended a controversial privacy technique being used by the U.S. Census Bureau in the 2020 census, a method the agency promised would only make small changes to actual numbers in counts of racial and ethnic groups. The technique called “differential privacy adds mathematical “noise,” or errors, to the data to obscure any given individual’s identity while still providing statistically valid information. Bureau officials say the change is needed to prevent data miners from matching individuals to confidential details that have been rendered anonymous in the massive data release expected as early as August. It will be applied to race, age and other demographic information in geographic areas within each state.

The Census Bureau said it is still formulating the details, but bureau officials have previously described trying to find “the sweet spot” between data confidentiality and data accuracy. Last month, the state of Alabama and Alabama politicians sued the Census Bureau and the Commerce Department, which oversees the statistical agency, claiming differential privacy will result in inaccurate data. On Monday, a pair of civil rights groups also raised concerns about differential privacy in a report. Differential privacy could lower the quality of the data used for redrawing congressional and legislative districts, according to a report from Mexican American Legal Defense and Educational Fund, also known as MALDEF, and Asian Americans Advancing Justice AAJC.
