This article presents some of the general findings and, in particular, the information on family planning practice in Isfahan City and Ostan compiled in two phases of the Isfahan Communications Project (ICP). In terms of information generated, the project had two main stages: (1) the ostan-wide sample presurvey (May, 1970), and (2) the ostan-wide mass media campaign (August, 1970-March, 1971). The presurvey was made to obtain demographic information and data on the knowledge, attitudes, and practice (KAP) of family planning among the population and their exposure to the various media. The media campaign was directed at those couples who because of their media behavior and previous experiences with contraception were thought to be predisposed to adopt modern family planning methods.
