Meeting Stats
Our archive of past meeting statistics provides a clear, data-driven look at how ACA meetings have grown and evolved, offering insight into attendance, abstract submissions, program participation, and other key indicators of community engagement. These records also reflect the ACA’s commitment to quality, equity, and transparency in our conference programs. Guided by our Conference Policy, we recognize the importance of speaking opportunities in shaping scientific careers and remain mindful of the historic under-representation of some groups. In alignment with our Speaker Invitation and Reporting Policies, we track and publish statistics on geographic and gender balance among invited speakers, selected speakers, session chairs, and attendees. By preserving and sharing this information, we celebrate the strength of our community, highlight our ongoing commitment to diversity and inclusion, and support thoughtful planning for future meetings.
