The Baltimore Longitudinal Studies of Aging began in 1958 in order to study physiological changes in healthy middle-aged and older men living in the community by testing them every two years on numerous physiological parameters. Older Americans Act training grants from the U. Administration on Aging to launch the nation’s first degree programs in gerontology, at the master’s level. Gerontological Education has flourished in the United States since 1967 and degrees at all academic levels are now offered by a number of colleges and universities.

In 1900, there were 3. However, this population continued to grow throughout the 20th century and reached 31. 3 million people in 1990, 2000, and 2010, respectively. Recently, the population aged 65 years and older has grown at a faster rate than the total population in the United States.

The total population increased by 9. 7 million, between 2000 and 2010. However, the population aged 65 years and older increased by 15. 65 years and older by 2025. Moreover, by 2050, it is predicted that, for the first time in United States history, the number of individuals aged 60 years and older will be greater than the number of children aged 0 to 14 years.

3 million to 21 million by 2050. 89 years constituted the greatest segment of the oldest-old in 1990, 2000, and 2010. However, the largest percentage point increase among the oldest-old occurred in the 90- to 94-year-old age group, which increased from 25. With the rapid growth of the aging population, social work education and training specialized in older adults and practitioners interested in working with older adults are increasingly in demand.

There has been a considerable disparity between the number of men and women in the older population in the United States. Therefore, the sex ratio is the number of males per 100 females. In 2010, there were 90. 5 males per 100 females in the 65-year-old population. However, this represented an increase from 1990 when there were 82. 7 males per 100 females, and from 2000 when the sex ratio was 88.

Conversely, all states exhibited an increase in the population of adults aged 85 years and older from 2000 to 2010. It involves interdisciplinary research on biological aging’s causes, effects, and mechanisms. 100 for children born after the year 2000. 50 chance of developing technology within about 25 to 30 years from now that will, under reasonable assumptions about the rate of subsequent improvements in that technology, allow us to stop people from dying of aging at any age”, leading to life expectancies of 1,000 years.

In contrast with biogerontology, geriatrics studies the treatment of disease in aging people. Theories of aging are numerous and no one theory has been accepted. There is a wide spectrum of the types of theories for the causes of aging with programmed theories on one extreme and error theories on the other. Regardless of the theory, a commonality is that as humans age, functions of the body decline. Wear and tear theories of aging suggest that as an individual ages, body parts such as cells and organs wear out from continued use.
