abstract="The diversity of the elderly population in Los Angeles County is studied by using the concept of life-style. Life-style is defined by a set of socioeconomic, demographic, and behavioral characteristics. A methodology is presented that uses factorial ecology techniques; the data required are commonly available from census and administrative sources in metropolitan areas. Factor analysis is applied to census tracts to define dimensions of life-style that represent the major differentiating characteristics of elderly populations. Homogeneous life-style groups among the elderly are then identified by clustering tracts that show similar life-style dimensions. Finally, analysis of variance is used to identify differences in the travel characteristics of life-style groups. An investigation of the elderly population of Los Angeles County was conducted as a case study. Seven dimensions were defined that provided a basis for the identification of seven elderly life-style groups. Each group was found to be unique in terms of travel demands and socioeconomic composition. Life-style groups were also found to reside in specific areas of the county, a necessary condition for meeting their transportation needs.<p />",
