Employing the political construct of "target" populations, we suggest that the Boomers in old age will constitute a conceptually distinct population from that represented by either their parents or grandparents. A fourfold typology organized along the dimensions posited by Schneider and Ingram (1993) yields categorizations of target populations as Dependent, Deviant, Advantaged, or Contender. Although these authors labeled the aged as Advantaged, categorizations of target populations can and do change over time. Using historical analysis, we explore, first, the transformation of the aged from Dependent to Advantaged and the more recent transformation to Contender status. This latest shift is reinforced by the perceived characteristics of the Boomer cohort itself now entering old age and by economic and political circumstances severely constraining policy agendas and options. We argue that the combination of weakened legitimacy in the face of pressing needs among many of the Boomer population may result in a fracturing of elders' longstanding singular political imagery. More affluent Boomers will continue to fight for their benefits as Contenders, whereas vulnerable Boomers may be relegated back to the Dependent categorization.
