Personas are widely used in design, and have recently spread to other fields such as policy-making and healthcare, where they help to convey the complexities of an ageing population. Policies and healthcare systems should rely on quantitative data to ensure the best impact on society, but no database exists that represents the aging population in a holistic and deep way, making it difficult to create effective personas. In this paper, we review the available surveys on the effects of aging, and propose three approaches that use these surveys to create better quantitative personas.
