This is the first published study to examine in detail the demographic factors associated with willingness to register as an organ donor at a state motor vehicles bureau. It uses registration counts controlling for the size of the general population as the measure of willingness. Local variation in registration levels is modeled as a function of a set of local socioeconomic, racial/ethnic, and immigration characteristics; cluster analysis of social areas is used to probe the effects of nonlinear combinations of local social environment factors. Results show that residence in high minority areas, lower-income areas, and immigrant-heavy areas depresses registration levels but also that significant nonlinear combinations of factors are at work. Specifically, minority/immigrant areas tend strongly to have lower registration counts controlling for population regardless of socioeconomic status (SES), whereas registration in less prosperous areas depends largely on the racial, ethnic, and immigrant proportions in those areas. Moreover, the very highest SES neighborhoods in the study area (northern California minus greater Sacramento) have very high levels of donor registration despite high racial, ethnic, and national origin diversity.
这是首篇公开发表的详细研究与在州机动车管理局登记成为器官捐赠者意愿相关人口因素的文章。它将控制了总人口规模的登记人数用作意愿衡量指标。登记水平的地区差异被建模为一组当地社会经济、种族/族裔和移民特征的函数；社会区域聚类分析用于探究当地社会环境因素非线性组合的影响。结果表明，居住在少数族裔聚居区、低收入地区和移民密集地区会降低登记水平，但同时也表明存在显著的因素非线性组合在起作用。具体而言，少数族裔/移民地区无论社会经济地位（SES）如何，往往在控制人口数量后登记人数较低，而较贫困地区的登记情况很大程度上取决于这些地区的种族、族裔和移民比例。此外，研究区域（北加利福尼亚减去大萨克拉门托地区）中社会经济地位最高的社区尽管种族、族裔和祖籍多样性高，但器官捐赠者登记水平却很高。
