economic, and political structures and trends, a fully informed discussion of
global longevity, its multiple dimensions, and the various policies, programs, and
interventions. Nonetheless, in this chapter I attempt to do three things. I present
and analyze the demographics of global aging, recognizing that the ongoing
longevity revolution is occurring in complex environments. I identify and discuss
three sets of policy and program challenges. Finally, I argue that evidence-based
approaches to policy and program development as well as clinical intervention
may be ideal, but note the unevenness in research resources and capacities that
can be brought to bear in both developing and developed nations.
To provide an initial comparative perspective, I examine China in comparison
to the United States. In some instances, I also provide a comparative view of
Japan’s response to the fact that 25% of its populace will be 65 years old and older
by 2020 and 38% will be over 60 in 2050 (United Nations, 1999).
THE DEMOGRAPHICS OF GLOBAL AGING
O
VERVIEW
Today, there are an estimated 6.5 billion persons in the world (U.S. Census Bu-
reau, 2006b). In mid-2005, about 1.2 billion persons resided in the more developed
world, with nearly 15% age 65 or older. This was significantly less than the 5.3 bil-
lion persons 65 or older (about 5%) in the developing world (Population Reference
Bureau, 2005). Of this, 605 million persons are 60 or older; an estimated 483.3 mil-
lion persons (7.46% of the world’s total population) are 65 or older. By 2025, it is
expected that 1.2 billion persons will be 60 or older. In 2050, the number of per-
sons 60 and older is expected to rise to almost 2 billion. At that point, the size of
the older adult population will exceed that of children (0 to 14 years) for the first
time in human history (HelpAge International, 2002).
Approximately 3.3% of the U.S. population of 3.3 million persons in 1990 was
65 or older; 100,000 were 85 or older. By midcentury, the number of persons over
65 had grown to 12.3 million, and by the beginning of the twenty-first century,
the elderly population in the United States had mushroomed to approximately 35
million older adults out of nearly 300 million persons (12%), 4.2 million of whom
were older than 85. The Federal Interagency Forum on Aging-Related Statistics
(2000, 2006) projects that in 2050 there will be 86.7 million persons 65 and older
and 20.9 million who will have reached age 85 or older.
In the United States, the equivalent of one small town (about 7,918 persons)
turns 60 each day (U.S. Census Bureau, 2006a). Regardless of how dramatic this
sounds, the rapidity of aging in the developing world is staggering. In 2000, for
example, the world’s entire elderly population (60 years and older) numbered 600
million, with the population of 374 million elders in developing countries grow-
ing at an astonishing rate of about 795,000 persons per month (Kinsella & Velkoff,
2001). By 2030, 75% of the world’s elders or 1 billion persons will be in developing
countries. In comparison, the number of older persons in developed countries is
likely to reach 362 million in 2030 (HelpAge International, 2002).
Approximately 27.4% of our global population is 0 to 14 years of age. In com-
parison, 65.2% of the world’s people are 15 to 65 years old. Confronted by dra-
matic population aging, Japan, Sweden, and other nations have developed societal
responses that may provide policy makers and professionals in the United States
with an expanded notion of policy and program possibilities.
