An analysis of prevailing marriages of various occupational strata is presented by cross-section survey methods. The data are viewed from the position of the male, of the female, and of the parent, with the findings in each case tending to confirm prior studies in showing a substantial amount of occupational endogamy. Marriage within the person's own or a contiguous stratum is highly typical. More higher-level persons marry down than up; more lower-level persons marry up than down.
