- This paper focuses, first, on the conceptual flaws inherent in conventional "standard mobility tables." Standard mobility tables completely ignore the timing of social mobility, and cannot control for the sojourn time at each occupational event. They ignore the unfolding of diverse career paths in one's lifetime and over generations. Cumulative mobility tables, which lately have been lauded by some researchers as a cure for such flaws in standard mobility tables, also suffer from conceptual difficulty, in that they confuse person and event as a unit of analysis in mobility tables. The main argument in this paper is that in order to overcome such flaws, we should incorporate the dimension of time in mobility tables. As one conceptually sound and practically simple solution, the paper suggests constructing person-year mobility tables. Using life history data from Korean National Migration Survey, the paper compares the three kinds of mobility tables, and discusses the merits of analyzing person-year mobility tables within the broader context of dynamic models for social mobility study.
