To synthesize knowledge concerning factors which affect occupational achievement through a set of explicit models based upon the concept of the socioeconomic life cycle, six major bodies of data from various sources were collected and subjected to secondary analysis. A number of items of lesser scope were gleaned from additional sources for use in particular analyses. The technique of path analysis was utilized as a methodological approach for interpreting choice of appropriate statistics. The basic model of occupational achievement specifies family socioeconomic background and educational attainment as influences on the level of occupational status achieved. National origin, race, family size, stability, intelligence, aspirations, motivation, influences of others, first job, migration, disruption of marriage, fertility, and child spacing were used in elaborations of the basic model, and income, subjective achievement, and occupational status were utilized as outcomes. Analysis of substantial bodies of data provided estimates of the relative strength of factors influencing achievement for the adult male population. (DM)
