In the literature on aging there have been almost simultaneous calls for re
searchers to make more explicit links between theory and research and for r
esearchers to incorporate diversity in their work. Although gerontologists
have begun to document diversity, theory is often absent from this research
. In this article, the author examines sociological aging theories of inequ
ality and argues that this absence of theory may not be due to an oversight
on the part of researchers. Rather, aging theories need to be rethought to
be better suited for diversity research.
