Zhrnutie	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 index of dissimilarity, often called the Duncan segregation index, measures how unevenly two groups — such as two racial or occupational groups — are distributed across a set of units like neighborhoods, schools, or occupations. It ranges from 0, when both groups have identical distributions across units, to 1, when the units are completely segregated, and has the intuitive interpretation of the share of one group that would have to relocate to achieve an even distribution.
