During school years, it is suggested that the stability of general peer friendships is largely determined by whether a friend stays in an individual's class from year to year (Cairns & Cairns, 1994). This data comes from a cohort (n=100) of the Carolina Longitudinal Study (CLS), followed from fourth to twelfth grade. The CLS sample, as a whole, was representative in terms of race, socioeconomic status, and parental occupations of the makeup of the midatlantic communities from which it originated.
