Abstract
Summary Sixty-eight engaged couples, 113 newly weds, and 222 couples married for over 5 years, were studied for a number of physical, psychological and socioeconomic traits. The measurements were repeated a year later. Correlations were highest for age (r = 0·454, 0·903 and 0·888 respectively). They were also high for height (but not weight), neuroticism (but not extroversion), occupation, education, religion and smoking. Similarities were already present about the time of marriage, with little convergence or divergence. Thus, men do not grow to resemble their wives, nor vice versa.
