This research attempts to replicate and extend the work of Litwak and Szelyeni on primary group structures in Hungary and the United States. Their findings indicated that proximity of kin and occupation affected primary-group relationships. Employing data drawn from interviews with 686 Irish women, we generally confirmed their findings; however, by means of a step-wise regression procedure we were able to show that occupational prestige was negatively correlated with kin usage in our three time-demand situations because of its association with low fertility in respondent's families of orientation and higher rates of geographic mobility.
