Population aging increases critical issues related to the abilities of governments and families to provide adequate resources and opportunities for individuals to maintain well-being levels throughout the life course and particularly at later life. Countries are responding to these challenges by enacting a number of reforms, such as introducing mandatory individual retirement accounts, prioritizing an expansion in explicit health guarantees and benefits packages, creating national aging services, and updating their official statistics to include emerging issues. Therefore, it is important to examine the effectiveness of these policy efforts and other alternatives in meeting the needs of older adults and promoting societies that age positively.
