Research problem: The ASEAN region is experiencing rapid population aging, with over 20% of the population in several countries projected to be aged 60 or above by 2050. This demographic shift necessitates the development of effective public policies that address the needs of older adults while harnessing their potential as contributors to society.

Objective: This study addresses two key research areas: (1) exploring effective public policies for happy and active aging in ASEAN countries, and (2) identifying determinants of expected retirement age and working hours among pre-retirees.

Methodology: The research employs a mixed-methods approach. Scoping reviews will be conducted to map effective public policies aligned with the WHO Active Aging Framework. Additionally, a survey will collect primary data from individuals aged 50–60 employed in the formal sector, while focus group discussions with employers will provide insights into barriers to hiring older workers, such as legal restrictions, cost concerns, and policy needs. A cross-objective analysis will integrate findings to develop tailored policy recommendations.

Expected outcomes: Expected outcomes include tailored policy recommendations that are evidence-based and context-specific, addressing the unique needs of ASEAN countries. The study will identify gaps in current aging policies, providing actionable insights to improve policy frameworks and support aging populations more effectively. By highlighting successful policies from individual ASEAN countries, the research will enhance regional collaboration, fostering knowledge sharing and the adoption of best practices. Ultimately, the recommendations will promote happy and active aging, creating environments that enhance the well-being and quality of life for older adults in the region.
