Students of human development increasingly recognize that chronological age is not necessarily the best and certainly not the only measure of an individual's "age." The present study is an examination of the attitudinal correlates of subjective age identification among the younger adults in a nationally representative sample of the United States in 1972. Respondents 18-24 and 25-35 years of age were categorized as those having a subjective young identification, and those not expressing an age identification. A number of multi-item attitude scales in such areas as political alienation, fiscal optimism, and political protest were included; analysis focused on impact which subjective age identification made on the attitudes and on the organization of those attitudes. Three general conclusions were documented: (1) A substantial proportion of the youngest age group exhibits a subjective young age identification, with the proportion being about half that in the 25-35 age group. (2) Subjective age identification does make a difference in both attitude-holding and attitudinal organization. Depending on the particular attitude examined, the subjectively young/and those with no subjective age identification exhibited different attitudinal patterns. (3) The influence of subjective age on sociopolitical attitudes is independent of variations in the socioeconomic status of the respondents. (Author)
