Supercentenarians are people living to 110 years or more. In August 2014, there were seventy-five verified supercentenarians worldwide—seventy-three women and two men. These are people whose age has been carefully documented, but there are almost certainly others who have not been identified. The Gerontology Research Group (2014) estimates there are between 300 and 450 people worldwide who are at least 110 years of age.
Centenarians are people living to be 100 years old, and they are approximately 1,000 times more common than supercentenarians. In 2010, there were about 80,000 centenarians in the United States alone. They make up one of the fastest-growing segments of the population (Boston University School of Medicine 2014).
People over ninety years of age now account for 4.7 percent of the older population, defined as age sixty-five or above; this percentage is expected to reach 10 percent by the year 2050 (U.S. Census Bureau 2011). As of 2013, the U.S. Census Bureau reports that 14.1 percent of the total U.S. population is sixty-five years old or older.
The aging of the U.S. population has significant ramifications for institutions such as business, education, the healthcare industry, and the family, as well as for the many cultural norms and traditions that focus on interactions with and social roles for older people. “Old” is a socially defined concept, and the way we think about aging is likely to change as the population ages.
Gerontology is a field of science that seeks to understand the process of aging and the challenges encountered as seniors grow older. Gerontologists investigate age, aging, and the aged. Gerontologists study what it is like to be an older adult in a society and the ways that aging affects members of a society. As a multidisciplinary field, gerontology includes the work of medical and biological scientists, social scientists, and even financial and economic scholars.
Social gerontology refers to a specialized field of gerontology that examines the social (and sociological) aspects of aging. Researchers focus on developing a broad understanding of the experiences of people at specific ages, such as mental and physical wellbeing, plus age-specific concerns such as the process of dying. Social gerontologists work as social researchers, counselors, community organizers, and service providers for older adults. Because of their specialization, social gerontologists are in a strong position to advocate for older adults.
Scholars in these disciplines have learned that “aging” reflects not only the physiological process of growing older but also our attitudes and beliefs about the aging process. You’ve likely seen online calculators that promise to determine your “real age” as opposed to your chronological age. These ads target the notion that people may “feel” a different age than their actual years. Some sixty-year-olds feel frail and elderly, while some eighty-year-olds feel sprightly.
Equally revealing is that as people grow older they define “old age” in terms of greater years than their current age (Logan 1992). Many people want to postpone old age and regard it as a phase that will never arrive. Some older adults even succumb to stereotyping their own age group (Rothbaum 1983).
In the United States, the experience of being elderly has changed greatly over the past century. In the late 1800s and early 1900s, many U.S. households were home to multigenerational families, and the experiences and wisdom of elders was respected. They offered wisdom and support to their children and often helped raise their grandchildren (Sweetser 1984).
Multigenerational U.S. families began to decline after World War II, and their numbers reached a low point around 1980, but they are on the rise again. In fact, a 2010 Pew Research Center analysis of census data found that multigenerational families in the United States have now reached a record high. The 2008 census data indicated that 49 million U.S. families, 16.1 percent of the country's total population, live in a family household with at least two adult generations—or a grandparent and at least one other generation.
Attitudes toward the elderly have also been affected by large societal changes that have happened over the past 100 years. Researchers believe industrialization and modernization have contributed greatly to lowering the power, influence, and prestige the elderly once held.
The elderly have both benefitted and suffered from these rapid social changes. In modern societies, a strong economy created new levels of prosperity for many people. Healthcare has become more widely accessible, and medicine has advanced, which allows the elderly to live longer. However, older people are not as essential to the economic survival of their families and communities as they were in the past.
Since its creation in 1790, the U.S. Census Bureau has been tracking age in the population. Age is an important factor to analyze with accompanying demographic figures, such as income and health. The population pyramid below shows projected age distribution patterns for the next several decades.
Statisticians use data to calculate the median age of a population, that is, the number that marks the halfway point in a group’s age range. In the United States, the median age is about forty (U.S. Census Bureau 2010). That means that about half of the people in the United States are under forty and about half are over forty. This median age has been increasing, which indicates the population as a whole is growing older.
A cohort is a group of people who share a statistical or demographic trait. People belonging to the same age cohort were born in the same time frame. Understanding a population’s age composition can point to certain social and cultural factors and help governments and societies plan for future social and economic challenges.
Sociological studies on aging might help explain the difference between Native American age cohorts and the general population. While Native American societies have a strong tradition of revering their elders, they also have a lower life expectancy because of lack of access to healthcare and high levels of mercury in fish, which is a traditional part of their diet.
In the United States, all people over eighteen years old are considered adults, but there is a large difference between a person who is twenty-one years old and a person who is forty-five years old. More specific breakdowns, such as “young adult” and “middle-aged adult,” are helpful. In the same way, groupings are helpful in understanding the elderly. The elderly are often lumped together to include everyone over the age of sixty-five. But a sixty-five-year-old’s experience of life is much different from a ninety-year-old’s.
The United States’ older adult population can be divided into three life-stage subgroups: the young-old (approximately sixty-five to seventy-four years old), the middle-old (ages seventy-five to eighty-four years old), and the old-old (over age eighty-five). Today’s young-old age group is generally happier, healthier, and financially better off than the young-old of previous generations. In the United States, people are better able to prepare for aging because resources are more widely available.
Also, many people are making proactive quality-of-life decisions about their old age while they are still young. In the past, family members made care decisions when an elderly person reached a health crisis, often leaving the elderly person with little choice about what would happen. The elderly are now able to choose housing, for example, that allows them some independence while still providing care when it is needed. Living wills, retirement planning, and medical power of attorney are other concerns that are increasingly handled in advance.
Gregory Bator founded the television show Graceful Aging and then developed a web site offering short video clips from the show. The purpose of Graceful Aging is to both inform and entertain, with clips on topics such as sleep, driving, health, safety, and legal issues. Bator, a lawyer, works on counseling seniors about their legal needs. Look at the Graceful Aging website for a visual understanding of aging.
