Gerodiversity  Gerodiversity is the multicultural approach to issues of aging. This approach provides a theoretical foundation for the medical and psychological treatment of older adults within an ecological context that includes their cultural identity and heritage, social environment, community, family system, and significant relationships (Iwasaki, Tazeau, Kimmel, Baker, & McCallum, 2009). Gerodiversity encompasses a social justice framework, which considers the social and historical dynamics of privilege and inequality (Iwasaki et al., 2009). In addition to issues of aging, gerodiversity includes race, ethnicity, language, gender identity, socioeconomic status, physical ability or disability, sexual orientation, level of education, country of origin, location of residence, and religion or spirituality. Gerodiversity builds on the field of clinical geropsychology, which applies psychological and developmental methods to understanding the behavioral, emotional, cognitive, and biological aspects of aging in the context of providing clinical care to older adults. The goal is to develop culturally competent, scientific methods for the psychological and medical treatment of the aging population (Iwasaki et al., 2009). According to this perspective, in order to ethically and scientifically provide optimal care to older adults, clinicians must be aware of the cultural factors in health care utilization, including use of physical and mental health care. Moreover, from this perspective, clinicians must continually work to improve their multicultural knowledge base, skill set, and attitudes towards cultural diversity. Increased awareness and attention to gerodiversity parallels the aging demography of the United States. Older adults comprise 14.5% of the U.S. population, with those aged 65 and older numbering 46.2 million (Administration on Aging [AoA], 2016). Dubbed "the Silver Tsunami", this segment of the population is rapidly growing, and the Administration on Aging expects it to double to 98 million older persons by 2060. Aging confers a unique risk of marginalization due to the intersection of advanced age and other disadvantaged factors. The domains of diversity discussed herein may intersect with age in such a way to confer a "double jeopardy" (Dowd & Bengston, 1978). More recently, attention has been paid to those who face a "triple threat of marginalization" (e.g., older lesbian women; Averett, Yoon, & Jenkins, 2011). As with other conceptualizations of diversity and marginalization, advanced age and other sociodemographic variables intersect and result in unique experiences for each group and individual. Below are a few highlighted areas for consideration.
