This new 190-page release from the Census Bureau and the National Institute of Aging (NIA) presents comparative data related to aging, including population and projected population internationally, life expectancy, retirement, health information, and social support. The report was, in part, inspired by a review from the National Academy of Sciences (NAS) that argued for an international focus on aging as an aid to policymakers worldwide. The main body of the report is broken into eleven chapters, covering topics ranging from urban versus rural populations to marital status to income security. Appendices include detailed tables, references, an international comparison of urban versus rural definitions, and sources and limitations of the data.
