Thesis title: THE ITALIAN DEMOGRAPHIC EVOLUTION AND ITS IMPACT ON CONSUMER BEHAVIOR
This thesis investigates the profound impact of Italy’s demographic evolution on consumer behavior over the past two decades (2004–2024). As one of the most rapidly aging societies in the developed world, Italy presents a compelling case for studying how shifts in age structure, fertility rates, and household composition are reshaping consumption patterns, market dynamics, and business strategies. Between 2004 and 2024, Italy’s median age increased from 42.3 to 46.6 years, and the old-age dependency ratio rose from 28.8% to 37.6%, reflecting significant structural transformations with wide-reaching implications. Drawing on 163 sources from academic studies, government reports, and longitudinal surveys, this review synthesizes findings across disciplines including economics, sociology, marketing, and behavioral science. The analysis integrates macro-level demographic trends with micro-level consumption data, offering a multidimensional view of how aging influences expenditure allocation, product preferences, financial behavior, and decision-making processes. Key theoretical frameworks employed include the Life-Cycle Hypothesis, Demographic Transition Theory, and Behavioral Economics, all of which provide complementary perspectives on the demographic-consumption nexus. The review addresses five central research questions, focusing on how Italy’s demographic changes have influenced household spending, which theoretical models best explain these dynamics, how effects differ across consumer segments and product categories, and what implications arise for businesses and policymakers. It also evaluates the methodological approaches used in existing research and highlights key knowledge gaps. Findings reveal that while aging is often associated with declining consumption, the reduction in spending is largely driven by shifts in preferences, health status, and lifestyle rather than by financial constraints alone. Older households allocate a higher share of expenditures to housing and healthcare, while younger families prioritize transport, education, and technology. Moreover, older consumers exhibit distinct behavioral traits—such as brand loyalty, reduced risk tolerance, and increased reliance on social and emotional cues—that challenge traditional marketing models. The demographic transformation also intersects with broader socioeconomic trends, including regional disparities, urban-rural divides, and changing household structures such as the rise of single-person and intergenerational households. These shifts call for more nuanced market segmentation strategies that move beyond chronological age to include psychological, social, and functional dimensions of aging. From a strategic perspective, the review emphasizes the need for age-inclusive product design, targeted communication strategies, and inclusive service models that cater to the evolving needs of older consumers. Policymakers must also address digital divides, health inequalities, and accessibility gaps to ensure active aging and equitable participation in economic and social life.
