Abstract: | Most research on career development is concerned with the fate of individuals, but portraits of the heterogeneity and development of whole populations or aggregates of individuals can also be useful for understanding the needs and development of different client populations. Two population-level concepts are proposed and defined: differentiation and distribution. This report then charts the rate at which occupational differentiation proceeds among 3730 young white men and investigates the personal and family attributes by which these men are distributed, or distribute themselves, to jobs. Data from the National Longitudinal (Parnes) Survey of the Labor Force Experience of Young Men are used to examine employment among men aged 16 to 28 in different levels and fields of work. Results suggest that the rate of labor force participation stabilizes in the early twenties, differentiation among men by education and the distribution of men among different broad levels and fields of work stabilize by the mid-twenties, and the sorting of men with different socioeconomic backgrounds into different occupational groups continues through the late twenties at which age it appears to have been largely completed. Discriminant analyses suggest that the distribution of men to jobs is primarily along an occupational status dimension, and secondarily according to field of work. Among the variables used in the analyses, academic achievement is the major dimension by which men are sorted or sort themselves to different jobs. |
