abstract="A statistical procedure for determining the chronological lower limits of sociological old age involves: (1) the establishment of norms of adulthood for various social criteria, (2) the determination of the ages at which deviations occur. The method will permit an inventory of sociological old age with reference to various indicia. It can be employed for the United States as a whole and for any subdivision by sex, color, occupation, and industry for such factors as labor-force participation, employment status, living arrangement and income.<p />",
