The purpose of this study was to report an update of demographic information about instructional developers. Six demographic characteristics from two studies on instructional developers in 1973 and 1976 were compared and discussed. It was concluded that the instructional development movement is attracting younger members and more female professionals. Although most instructional developers were found in higher education and engaged in a broad range of professional activities, the location of instructional developers was becoming more geographically dispersed. An overall analysis of demographic characteristics of instructional developers indicated that instructional development has experienced positive growth since 1973. (Author)
