Every ten years the U.S. Census Bureau conducts a nationwide survey that sets the terms for the country’s democracy. The questionnaire yields rich data, including people’s names, street addresses, ages, races, ethnicities, and other details. People’s responses help determine dynamics of power, such as how seats are apportioned in the House of Representatives, where voting districts get divided, and which communities receive federal funds.
But the bureau, tasked with releasing summaries of the results while simultaneously protecting people’s privacy, faces a Catch-22. “Every time you publish a statistic you leak information about that confidential database,” as Simson Garfinkel, a computer scientist with the bureau, told a Census advisory committee in May.
