The National Association for Public Health Statistics and Information Systems (NAPHSIS) is a national association of state vital records and public health statistics offices which is based in the Washington, DC area. The association was formed in 1933 to provide a forum for the study, discussion, and solution of problems related to these programs in the respective members' health departments. NAPHSIS provides national leadership for both vital records and related information systems in order to establish and protect individual identity and improve population health.
