This study analyses determinants of the presence of an intimate partner during face-to-face
interviews. Based on theoretical assumptions about opportunity structure, social control,
social support, and companionship, we investigated partner presence using data from the first
wave of the German Family Panel (pairfam). Descriptive results revealed that an intimate
partner was present in every seventh interview. Multivariate results using separate logistic
regression models for the presence of the female (n = 3,272) and the male partner (n = 2,348)
revealed that the opportunity structure, such as the couple’s living arrangements or their
employment status, had the greatest influence on the presence of both female and male
partners. Gender differences existed for social control, social support and companionship.
The results suggest that partner presence could most easily be prevented by taking into
account the opportunity structure
