Most of these countries have lower levels of development and industrialization.
The age structure of the United States continues to be influenced by the large birth cohorts of the baby boom people born from through who are not yet age The South had the largest number of people aged 65 and up, while the Northeast had the largest percentage of people aged 65 and up.
All regions are expected to see an increase, although it should be milder in some regions, such as Africa, where the projected increase is from 3.

Another factor that may contribute to the greater life expectancy of women is the different types of jobs men and women tend to have during their lifetimes, with men more frequently doing physical labor that could wear the body down or increase the odds of injury. The Institute's Director, Professor Sarah Harper highlights in her book Ageing Societies  the implications for work, families, health, education, and technology of the ageing of the world's population. The median age—the age at which exactly half the population is older and half younger—is the most widely used indicator. A society is considered relatively old when the proportion of the population age 65 and over exceeds 8 to 10 percent. It was the first theory of aging that social scientists developed. The proportion of the world population age 65 and over increased from 5. Demographers commonly use population pyramids to describe both age and sex distributions of populations. Increasing attention is paid to the "oldest olds" typically defined as persons age 80 and over , a category that is expanding rapidly.
Because elderly people are more inflation averse, countries with more elderly tend to exhibit lower inflation rates . However, while the trend of a growing older population appears world over, people in industrialized nations are older than people in non-industrialized nations.

Defining and Measuring Because the study of population aging often is driven by concern about the burden it imposes on retirement systems, the aging of population often is measured by increases in the percentage of people in the retirement ages. As populations age, the prevalence of disability, frailty, and chronic diseases Alzheimer's disease, cancer, cardiovascular and cerebrovascular diseases, etc. In , 53, centenarians, or people over the age of , lived in the United States, a 5. WHO has developed guidelines that help countries to understand the types of programmes they can put in place to improve healthcare settings and cities so they are better suited to the needs of older people. There appear to be regional divides in the demographic breakdown of senior citizens. By , the number of senior citizens had increased to 35 million out of million Americans. There is a disparity between industrialized and non-industrialized nations; people live longer in industrialized countries. Increase in Health Care Costs Given that demand for health care rises with age, countries with rapidly aging populations must allocate more money and resources to their health care systems. Borji Updated Jul 25, The social and economic implications of an aging population are becoming increasingly apparent in many industrialized nations around the globe. Additionally, the health care sector in many advanced economies faces similar issues, including labor and skills shortages, increased demand for home care and the need to invest in new technologies. Aging and Race Individuals with different racial backgrounds tend to have different experiences with old age. The various forms that elderly care services can take include assisted living, adult day care, long-term care, nursing homes, hospice care, and in-home care. The proportions of elderly people are lower outside of Europe, with the notable exception of Japan, where this figure increased from 4.
Regardless of what the Supreme Court decides, American seniors face serious financial troubles, compounded by their healthcare needs. As advanced economies become older over the next 15 years, it remains to be seen whether immigration will fill the voids in sectors left by aging populations or whether the broader economies will have to adjust to changing demographics.
Aging population statistics by country
By , however, the aging index is projected to exceed in all developed countries, and the indexes for several European countries and Japan are expected to exceed Several factors contribute to the overall trend. The number of persons aged 80 years or over is projected to triple, from million in to million in The rate at which the population ages is likely to increase over the next three decades;  however, few countries know whether their older populations are living the extra years of life in good or poor health. Population aging also presents a great challenge for health care systems. Asia and Europe are the two regions where a significant number of countries face population ageing. Youthful populations are represented by pyramids with a broad base of young children and a narrow apex of older people, and older populations are characterized by more uniform numbers of people in the age categories. Older people have higher accumulated savings per head than younger people, but spend less on consumer goods. Another indicator of the age structure is the aging index sometimes referred to as the elder—child ratio , which is defined as the number of people age 65 and over per youths under age Forms of discrimination: economic accessibility, social accessibility, temporal accessibility and administrative accessibility.
