MONTGOMERY, Ala. – The fight over whether the U.S. Census Bureau can use a controversial statistical technique to keep people's information private in the numbers used for drawing political districts on Monday was going before a judicial panel which must decide if the method provides enough data accuracy.
A panel of three federal judges was hearing arguments on whether the method known as “differential privacy” meets the federal legal requirement for keeping private the personal information of people who participated in the 2020 census while still allowing the numbers to be sufficiently accurate for the highly-partisan process of redrawing congressional and legislative districts.
