Data from the 1970 U.S. census permit the most complete test of status integration theory ever undertaken, one based on four sets of achieved statuses (employment, household, marital, and residential) and three sets of ascribed statuses (age, race, and sex). A series of “between-columns” tests does not support the theory; and, contrary to expectations, simultaneous measures of status integration (i.e., measures based on a cross-classification of all four sets of achieved statuses) do not improve the theory's predictive accuracy. However, there is a substantial inverse relation among age-race-sex groups between the suicide rate and the measure of occupational integration; and that finding, together with numerous previous positive tests, precludes a categorical rejection of the theory. Nonetheless, the theory assumes that all statuses are relevant and approximately to the same degree, and the findings are contrary to that assumption.
