Black Lives Matter co-founder Alicia Garza launched a project earlier this week that could become “the largest [survey] of Black people in recent history.”

The Black Census Project aims to hear from 200,000 Black people online and through a door-knocking campaign in 20 states, which were selected based on their “concentration of black Americans, black LGBT communities and black immigrants, among other black demographics,” Mic reported.

The effort is part of Black Futures Lab, an initiative the organizer launched in partnership with Demos, Color of Change, the Center for Third World Organizing, Socioanalitica Research, and the Tides Foundation to build “the capacity of Black communities to live powerfully,” Garza told Rewire in a phone interview on Thursday. For the Black Futures Lab, which also launched on Monday, “it’s really important to offer a bigger picture of who Black people are, so that we can engage Black people differently and change the quality of life for Black people in general,” said Garza.
