The group also promotes information sharing among data users about key ACS data issues and applications. Membership is free and open to all interested ACS data users.
To facilitate communication among ACS data users, the Census Bureau and Population Reference Bureau maintain the ACS Online Community where people can share messages, materials, and announcements related to the ACS. We also plan the ACS Data Users Conference.
