Gray Power came into prominence in the 1970s and has received considerable attention among social gerontologists. This paper reviews studies on gray power, political consciousness among the elderly and advocacy by organizations on behalf of older people, and it considers their implications for further research. Constructing the agenda for future research on gray power requires recognizing the diversity of older people and the life-course context through which individuals shape their concepts of old age and its meaning. Studies on political power need to be longitudinal as well as cross-sectional. Furthermore, studies on the political power of older people should consider how the young and middle-aged perceive their power relative to issues of common concern. Finally the studies of age advocacy groups should be linked with those of other advocacy organizations involved in social change (e.g. the disabled). The paper concludes that research on gray power should be fostered along inter-disciplinary lines of inquiry.
