The Study on global AGEing and adult health (SAGE) is run by the World Health Organization. An objective for SAGE is to compile comprehensive longitudinal data on the health and well-being of adult populations and the ageing process across different countries, through primary data collection, secondary data analysis and cross-study collaborations.
The National Archive of Computerized Data on Aging (NACDA), located within ICPSR, is funded by the National Institute on Aging (NIA). NACDA's mission is to advance research on aging by helping researchers to profit from the under-exploited potential of a broad range of datasets. NACDA acquires and preserves data relevant to gerontological ...
In 2020, the median age of the United States is 38.8, up from 37.2 in 2010, [42] 35 in 2000, and 30 in 1980. [55] An increase in median age is seen among all ethnic groups, though European Americans are currently the oldest by that measure, followed by African Americans and Asian Americans (including Amerindians and Native Alaskans); [39 ...
The activity theory of aging, also known as the implicit theory of aging, normal theory of aging, and lay theory of aging, proposes that aging occurs with more positive outcomes when adults stay active and maintain social interactions as they get older. [1] Activity theory suggests that the aging process is slowed or delayed, and quality of ...
Population ageing is an increasing median age in a population because of declining fertility rates and rising life expectancy. Most countries have rising life expectancy and an ageing population, trends that emerged first in developed countries but are now seen in virtually all developing countries. In most developed countries, the phenomenon ...
In computing, file system fragmentation, sometimes called file system aging, is the tendency of a file system to lay out the contents of files non-continuously to allow in-place modification of their contents. It is a special case of data fragmentation. File system fragmentation negatively impacts seek time in spinning storage media, which is ...
Software aging. In software engineering, software aging is the tendency for software to fail or cause a system failure after running continuously for a certain time, or because of ongoing changes in systems surrounding the software. Software aging has several causes, including the inability of old software to adapt to changing needs or changing ...
Biogerontology is the sub-field of gerontology concerned with the biological aging process, its evolutionary origins, and potential means to intervene in the process. The term "biogerontology" was coined by S. Rattan, and came in regular use with the start of the journal Biogerontology in 2000. It involves interdisciplinary research on the ...
