Welcome to the American Community Survey (ACS) Online Community!

The ACS Online Community is a site where members can share messages, materials, and announcements related to ACS data, methods, and events.

Do you have a question or information you’d like to share about the ACS? The ACS Online Community is a resource for everyone, from novice to advanced ACS data users. No question is too simple or complex.

You will need to become a member to start or join a discussion. Membership is free and open to all interested ACS data users! We occasionally send email notifications to members regarding important ACS news or events. We do not share member information with third parties.

Posting a Comment or Question in the Discussion Forum

  • Navigate to the Discussion Forum.
  • Select a topic of interest and click   to respond to an existing discussion thread, or click the   button in the upper right corner of the page to start a new discussion.
  • Provide a subject for your post and add one or more tags.
  • Type your question or comment in the Description box. You can add images and other files to your post by dragging them into the editor.
  • The Discussion Forum is not just for questions. Feel free to share ideas, feedback, programming code, or links to relevant resources related to ACS data.
  • Check your post for any spelling and grammatical errors.
  • Click   at the bottom of the page to share your message with other ACS data users.
  • Your first post to the Discussion Forum will be placed in a moderation queue for review before it is posted.
