According to population projections from the United Nations, the global population age 65 and older will triple over the next 40 years from 0.5 billion in 2010 to 1.5 billion by 2050, increasing the share of old people from 8% to 16%. There is a shift toward older age brackets in almost every country as people live longer and have fewer children. Workforce growth is slowing almost everywhere and in many countries workforces are actually shrinking as populations age.

Although population aging is a global phenomenon, large variations in the timing and pace of fertility declines and longevity gains create dramatic differences across countries. Because these demographic developments and their divergent patterns have significant implications for economic growth and political stability, understanding how they are likely to unfold is critical for addressing them wisely.


“SCL/PRB Index of Well-Being in Older Populations,” June 2011
Developed by the Stanford Center on Longevity and the Population Reference Bureau, this Index facilitates cross-national comparisons of well-being in older populations and can be used to determine which factors contribute to a country’s relative standing. The report describes the methodology used to develop the Index and summarizes 12 key indicators of material, physical, social, and emotional well-being in the United States and 11 European Countries.
