The Gerontological Society of America (GSA) is the nation's oldest and largest interdisciplinary organization devoted to research, education, and practice in the field of aging. The primary purpose of the Society — and its 5,400+ members — is to advance the study of aging and disseminate information among scientists, decision makers, and the general public. GSA includes two special units: The Association for Gerontology in Higher Education (AGHE) and the National Academy on an Aging Society (Academy). AGHE is a unique network of institutions dedicated to advancing scholarship in gerontology. The Academy, a non-partisan public policy institute, actively conducts and compiles research on issues related to population aging and provides information to the public, the press, policymakers, and the academic community.
