In order to describe and predict career patterns of young men, this report provides: (1) Markov chains of the career patterns for four groups of 5,225 young men divided according to race and age, (2) tests of the predictive validity of the chains, and (3) comparisons of the four race-groups using the Markov models. Using the Holland occupational classifications, initial interviews revealed statistically significant differences among the four groups. For instance, younger men generally showed a narrower range of occupational experience. For black men, the narrow range of experience persisted for the older group. Older white men held jobs in a broader range of occupational categories, and were more stable in their initial occupational categories. An attempt to establish the predictive validity of two of the four models was largely unsuccessful, indicating that the derived models could not be generalized. Since the Markov models did not improve the predictive efficiency of the Holland occupational classification, it is predicted that the subjects would maintain the Holland category of their initial occupation.
