Global population aging is a triumph of increased longevity and falls in fertility. More people are surviving to older ages due to health and development progress. However, aging populations risk being seen as a crisis rather than opportunity. To prepare, communities must act early, strategically, positively, and together. Aging will impact all areas of society so all generations must see older people as contributors and partners rather than problems. Aging should be a priority in global development frameworks to ensure older people's rights and wellbeing.
