The Republican Plan to Reform the Census Could Put Everyone’s Privacy at Risk

President Donald Trump and the Republican Party have spent the better part of a second presidential term make radical changes The federal government. But in recent weeks, the GOP has set its sights on taking another run at an old target: the U.S. census.

From the first Trump administration, the right has sought Add a question In censuses that capture a respondent’s immigration status and Exclude non-citizens The tallies determine how congressional seats are distributed. Supreme Court in 2019 to hurt It is the first Trump administration attempt to add a citizenship question to the census.

But now, a little-known algorithmic process called “Differential privacy,” designed to prevent Census data from being used to identify individual respondents, has become Dunn’s latest focus. WIRED spoke with six experts about the GOP’s ongoing effort to falsely allege that a system designed to protect people’s privacy falsified 2020 Census data.

If successful, the campaign to get rid of differential privacy could not only radically change the types of data available, but put the data of every person living in the United States at risk. The campaign may discourage immigrants from participating in the census altogether.

The Census Bureau regularly releases anonymized data for use by policymakers and researchers. That data is also sensitive: Conducted every 10 years, the census counts every person living in the United States, citizens and noncitizens. The data includes details such as race, gender and age, as well as the language they speak, their home address, economic status and the number of people living in a household. this Data is used to allocate federal funds that support public services such as schools and hospitals, as well as how a state’s population is divided and represented in Congress. The more people in a state, the more congressional representation—and the more votes in the Electoral College.

As computers became increasingly sophisticated and data became more abundant and accessible, census workers and researchers realized that data released by the Census Bureau could be reverse engineered to identify individuals. According to Title XIII of the US CodeIt is illegal for census workers to release any information that would identify individuals, their homes or businesses. A government employee is disclosing such information may be punished with thousands of dollars in fines or even possible prison terms.

For individuals, this could mean, for example, that one could use census data without differential privacy to identify transgender youth, according to Research from the University of Washington.
