Over the next 20 years, Hong Kong will face a rapidly aging population as the number of older adults aged 65 or above increases to approximately 1.4 million by 2021, that is, 17% of the total population. In 2001, there were 1.2 million adults aged 45-59. To assess the differences between these middle-aged adults and the current cohort of older adults, we identified the challenges that Hong Kong society will face in meeting the financial needs of older adults in the coming two decades. In this paper, we examine the retirement economic status of three groups of older adults: those who are financially independent, those who are financially supported by their adult children or children-in-law, and those who are receiving welfare assistance. We describe the current situations of these groups, prevailing social policy, future trends, and recommend policies for tackling problem areas.
