Facebook Inc. will ban content that misrepresents the 2020 U.S. census to suppress participation by minority communities, the latest step by the social media company to quell criticism from civil rights advocates.

Facing accusations that it hasn't done enough to curb efforts aimed at discouraging minorities, Facebook said Sunday it's developing a policy to be unveiled later this year that would prohibit distortions of census requirements, methods or logistics in postings.

The policy is among several changes Facebook announced in a report on its continuing civil rights audit, which is reviewing discrimination and biases on the social media platform. The study was conducted by civil liberties advocate Laura Murphy and Relman, Dane & Colfax PLLC, a law firm handling anti-discrimination issues. A final report is due next year.
