Sammanfattning	The Bogardus social distance scale, devised by Emory Bogardus in 1925, measures the degree of acceptance or rejection people feel toward members of other social, ethnic, or national groups. Respondents indicate the closest social relationship they would willingly accept with a target group, across an ordered series ranging from marriage and close friendship through neighbor and coworker down to exclusion from the country. Because the items form a cumulative (Guttman-type) hierarchy, a single score summarizes how much social distance a person places between themselves and each group.	Homophily analysis quantifies the tendency of similar individuals to form ties — the principle that 'birds of a feather flock together'. It compares the rate at which people connect with others who share an attribute (race, gender, age, education, attitudes) against what would be expected by chance, distinguishing the homophily that arises merely from group sizes from the genuine, behavior-driven preference for similar others.
