A good place to start would be the website of the National Civic League, a comprehensive organization that reports on many different aspects of urban affairs.
More specifically, an introductory article on equity can be found at https://www.nationalcivicleague.org/racial-equity-tools-for-communities/, while a listing of different equity resources is at https://www.nationalcivicleague.org/equity-resources/
We hope these sources may be helpful to you. Thank you for writing us at the Community Tool Box, and all best wishes as your important work proceeds.
