On April 20, 2017, the U.S. Census Bureau hosted a meeting with approximately 20 representatives from the health data community. Attendees included representatives from health information exchanges (HIEs), state and local public health departments, health data associations, and the Department of Health & Human Services (see Appendix A for list of participants). The purpose of the meeting was to explore the potential for a joint Census-HIE initiative: specifically, data maintained at the Census Bureau would be matched to records maintained by HIEs.
