Aging Studies

The Association for Gerontology in Higher Education (aka AGHE) is the international leader in advancing education on aging and is the only institutional membership organization devoted primarily to gerontology and geriatrics education since 1974. AGHE's mission is two-fold: (1) To advance gerontology and geriatrics education in academic institutions; and (2) To provide leadership and support of gerontology and geriatrics education faculty and students at education institutions.

The Gerontological Society of America is the oldest and largest interdisciplinary organization devoted to research, education, and practice in the field of aging. GSA’s principal mission — and that of our 5,200 members — is to advance the study of aging and disseminate information among scientists, decision makers, and the general public. We foster collaboration between biologists, health professionals, policymakers, and behavioral and social scientists. We believe the intersection of research from diverse areas is the best way to achieve the greatest impact and promote healthy aging.

The mission of the International Association of Gerontology and Geriatrics is to promote the highest levels of achievement in gerontological research and training worldwide, and to interact with other international, inter-governmental and non-governmental organizations in the promotion of gerontological interests globally and on behalf of its member associations. The Association pursues these activities with a view of enhancing the highest quality of life and well being of all people as they experience ageing at individual and societal levels.

Founded in 1954 as the Western Gerontological Society, the American Society on Aging is an association of diverse individuals bound by a common goal: to support the commitment and enhance the knowledge and skills of those who seek to improve the quality of life of older adults and their families. The membership of ASA is multidisciplinary and inclusive of professionals who are concerned with the physical, emotional, social, economic and spiritual aspects of aging.

The American Geriatrics Society (AGS) is a not-for-profit organization of over 6,000 health professionals devoted to improving the health, independence and quality of life of all older people. The Society provides leadership to healthcare professionals, policy makers and the public by implementing and advocating for programs in patient care, research, professional and public education, and public policy.

The National Council on Aging (NCOA) is a respected national leader and trusted partner to help people aged 60+ meet the challenges of aging. Our mission is to improve the lives of millions of older adults, especially those who are struggling. Through innovative community programs and services, online help, and advocacy, NCOA is partnering with nonprofit organizations, government, and business to improve the health and economic security of 10 million older adults by 2020.

The older population--persons 65 years or older--numbered 39.6 million in 2009 (the latest year for which data is available). They represented 12.9% of the U.S. population, about one in every eight Americans. By 2030, there will be about 72.1 million older persons, more than twice their number in 2000. People 65+ represented 12.4% of the population in the year 2000 but are expected to grow to be 19% of the population by 2030. The information in this section of the AoA website brings together a wide variety of statistical information about this growing population.

NIA, one of the 27 Institutes and Centers of NIH, leads the federal government in conducting and supporting research on aging and the health and well-being of older people. The Institute seeks to understand the nature of aging and the aging process, and diseases and conditions associated with growing older, in order to extend the healthy, active years of life. In 1974, Congress granted authority to form NIA to provide leadership in aging research, training, health information dissemination, and other programs relevant to aging and older people. Subsequent amendments to this legislation designated NIA as the primary Federal agency on Alzheimer’s disease research.
