This study examines the visual representation of population policies on Turkish postage stamps from 1927 to 1965, a period marked by significant demographic shifts and policy transformations. While extensive research has explored the use of postage stamps in nation-building and public communication, there remains a lack of scholarship investigating their role in articulating evolving population policies. This research addresses this gap by conducting a comprehensive analysis of Turkish census and population-themed stamps, situating them within the broader context of the nation's demographic objectives and sociopolitical landscape. Employing a mixed-methods approach, the study combines quantitative content analysis with qualitative iconographic interpretation to decode the visual rhetoric of these philatelic materials. Drawing from the PTT Stamp Museum Archive, we systematically analyzed stamp designs, symbolism, and textual elements to trace the evolution of population policy messaging over time. Our findings reveal a visual narrative that mirrors Turkey's transition from pronatalist to antinatalist policies. Early stamps emphasized total population figures and national mapping, reflecting the young republic's focus on demographic growth and territorial consolidation. As Turkey's population policy shifted, stamp iconography evolved to incorporate modern family imagery and infographic elements, subtly promoting smaller family sizes and population control. This research contributes to the growing body of literature on visual culture in policy communication and offers insights into the intersection of philately and demography.
