Redistricting Data Hub
"The nonpartisan Redistricting Data Hub (RDH) was founded by experts with backgrounds in pioneering redistricting legal cases, the establishment of independent redistricting commissions, and related ballot initiatives in Florida, Arizona and other states. It is a project of the Fair Representation in Redistricting Initiative, a project of New Venture Fund (NVF). RDH believes an effective democracy requires fair representation. Its goal is to provide individuals, civic organizations, and good government groups the data, tools, and knowledge to participate effectively in redistricting processes by learning how to define their communities, provide meaningful public input, recognize gerrymandering, and advocate for fair and legal maps."
