Need Help?


AskD3 is our community request system. You can submit data questions or requests and get connected to the right person to guide you to the answer.

Just AskD3!

Send us your questions or requests and we’ll connect you to someone on our team who can guide you to the answer.

If you’d like virtual data assistance, we offer weekly sessions through Co.act Detroit. Registration is required.

AskD3 is made possible thanks to Co.act Detroit, and the previous generous support from the Ralph C. Wilson, Jr. Foundation, and The Kresge Foundation.
