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.	The isolation index measures the exposure dimension of segregation: the extent to which members of a minority group are exposed only to one another rather than to members of other groups. It answers the question 'what is the own-group share of the typical neighbor (or classmate, or coworker) that a member of the focal group encounters?' Unlike evenness measures, it depends on the relative size of the group as well as its spatial distribution.
