Mayor Mamdani’s mass data release sparks criticism over privacy and class bias

Mayor Zohran Mamdani encouraged the Department of Finance to issue a public roster of property owners after it sent tax notices to roughly 17,000 suspected non-resident owners. The department’s broader publication included hundreds of thousands of names, addresses and market values, a dataset the agency itself admits is at least 95% incorrect. Many of the mailed tax bills were also sent to the wrong people, leaving them three weeks to demonstrate that their homes are occupied full-time.

Observers contend the mayor’s action was intended to embarrass affluent absentee owners rather than provide genuine transparency. The move contrasts with the city’s practice of keeping arrest records, cash-assistance applications, and rent-stabilized tenant lists confidential. Critics label the approach demagogic and contrary to the mayor’s pledge to unite New Yorkers.
