By 2050, the number of people aged 65 and older will reach 1.6 billion, or one in six people worldwide. In Europe and North America, the ratio will rise to one in four, and in countries like Japan, South Korea and Italy, it will exceed one in three. At the same time, birth rates are declining and one in four people now live in a country where the size of the population has already peaked. The longevity economy presents unique opportunities for actuaries. This collaborative session invites actuaries from across sectors to explore how our profession can respond to the evolving dynamics of population aging, health disparities, and intergenerational demands across society and the workforce. Together, we'll discuss how retirement design, public program sustainability, caregiving, and financial wellness will need to evolve -- and the actuary's role in this shift. What attendees will learn by attending the session: - How shifting demographic trends are impacting the sectors that actuaries work in - Practical levers for actuaries to support system resilience and well-being in light of demographic changes - Cross-sector implications for actuaries, including retirement, health, and long-term care - Opportunity to connect with peers to surface shared challenges and opportunities for innovation
