Summary
This paper introduces a set of 30 "basic senior personas" representing European citizens aged 60 and older, developed using a quantitative approach based on micro-level data from approximately 12,500 individuals across 17 European countries from the SHARE (Survey of Health, Ageing and Retirement in Europe) database. The work addresses four problems with existing personas for older adults: design teams often lack experience with this heterogeneous population; current senior personas are based on small-scale qualitative studies and lack representativeness; persona development is time-consuming, costly, and requires specialized skills; and most personas are project-specific and cannot be reused. The methodology involved analyzing requirements from 73 ICT projects for older adults, mapping those requirements to SHARE variables, performing partitional cluster analysis on eight key cluster variables (self-perceived general health, ADL limitations, cognitive function, home care services use, economic situation, social activities, and family aspects), and generating five clusters per variable combination across three European regions (central, northern, southern) and two age groups (60-79, 80+), resulting in 30 persona skeletons. These were enriched with additional variables covering demographics, physical health, mental health, cognitive functioning, behavioral risks, healthcare, social activities, and psychological well-being, then translated into narrative descriptions with graphical representations.
Key findings
The personas build on a layering framework that separates a reusable "basic" layer (durable characteristics like health status, demographics, and capabilities) from a context-specific "external" layer (goals and behaviors for specific use contexts). This allows the same basic personas to be reused across different projects with context-specific extensions. Each persona includes a fictitious name, photo, graphical information representations using icons and emoticons (e.g., a house for housing situation, a piggybank for finances), a detailed narrative description organized into sections (family, health, social), and a trait list with precise health-related information (ADL limitations, diseases, symptoms, hearing, eyesight, drug usage, etc.). A reflection workshop with 6 experienced researchers and designers found the personas easy to read and understand, close to reality, satisfying in included information and detail level, and generated high intention to use. The tools — including an online filter for pre-selecting personas by region, age, living condition, cognitive and mental health — were made freely available. Key data insights included that IADL limitations increased from under 10% for ages 50-59 to nearly 50% for ages 80+, with significant regional variations across Europe.
Relevance
This paper provides a practical, cost-efficient design tool that helps teams building technology for older adults move beyond stereotypes and age-range generalizations. For accessibility practitioners, the personas highlight that "older adult" is not a monolithic category — the spectrum encompasses individuals with very different health conditions, cognitive abilities, social situations, and capabilities. The quantitative, data-driven approach ensures the personas reflect actual population distributions rather than designer assumptions. The layering framework is particularly valuable: teams can start with representative basic personas and add project-specific context, dramatically reducing the time and cost of persona development. The inclusion of cognitive functioning, ADL limitations, mental health, and sensory capabilities (hearing, eyesight) alongside demographics makes these personas especially relevant for accessible technology design. For organizations developing products for aging populations — an increasingly important market as global populations age — these personas provide an evidence-based foundation for inclusive design decisions.
