To determine which demographic factors favor rural communities obtaining physicians, county characteristics of National Health Service Corps sites are analyzed. Through the use of a difference of means test, sites which were staffed at least once are compared with sites which were never able to obtain physicians. Since a major portion of the sites never staffed were located in the Southeast, the effect of "southeast location" as a separate, binary variable is considered. Five factors related to income, employment and education significantly (p less than 0.01) distinguish the staffed from the "never-staffed" sites. A function derived from discriminant analysis correctly classifies more than 70 per cent of the sites as staffed or never-staffed; inclusion of the southeast variable increases the number of correctly classified sites by 6 per cent. Given the presence of both socioeconomic and nondemographic constraints on rural communities, significant improvements in physician distribution may require that programmatic interventions be intensified.
为了确定哪些人口统计学因素有利于农村社区获得医生，我们分析了国家卫生服务团驻地的县特征。通过使用均值差异检验，将至少有一次配备人员的驻地与从未能够获得医生的驻地进行比较。由于大部分从未配备人员的驻地位于东南部，因此将“东南部位置”作为一个单独的二元变量的影响考虑在内。与收入、就业和教育相关的五个因素在显著水平（p小于0.01）上区分了配备人员的驻地和“从未配备人员”的驻地。从判别分析得出的一个函数正确地将超过70%的驻地分类为配备人员或从未配备人员；纳入东南部变量将正确分类的驻地数量增加了6%。鉴于农村社区存在社会经济和非人口统计学方面的限制，医生分布的显著改善可能需要加强计划性干预。
