PHYSICAL ATTRACTION AND EARLY DATING DYNAMICS
The data in the opening excerpt give a glimpse of the large number of cohabiting couples in the United States by year 2000. This survey was of couples in the age range between 18 and 30. Thus, for total number of cohabiting couples, the number should be in the millions. Presumably, so many young couples are interested in cohabiting because such a step allows them to test out the possibilities of marriage.
