On Measuring Segregation in Samples With Small Units
小规模单位样本中的群体隔离测度
Standard indexes of segregation measure a sample's distance from evenness, which occurs when each sample unit ( e.g., an occupation) has the population share of both the minority and majority groups. The authors show that random allocation of individuals to units generates substantial unevenness among small units and, hence, that standard segregation indexes reflect random allocation as well as systematic group segregation. They then modify two popular indexes so that they…
