To investigate whether enumeration district (ED) level data reflect the aggregate characteristics of people living in that district better than ward level analysis.
Reanalysis of the fourth national morbidity survey in general practice (MSGP4). Socioeconomic data on patients who had consulted 60 practices over one year were linked via postcode to ED and thence to small area statistics data for that ED and to the corresponding electoral ward.
There was no evidence that patients were likely to be more representative samples of the population of an ED than of a ward.
调查枚举区(ED)层面的数据是否比选区层面的分析能更好地反映该区域居民的总体特征。
对第四次全国全科医疗发病率调查(MSGP4)进行重新分析。通过邮政编码将一年内咨询过60家医疗机构的患者的社会经济数据与枚举区相关联,进而与该枚举区的小区域统计数据以及相应的选举选区相关联。
没有证据表明患者作为枚举区人口的样本比作为选区人口的样本更具代表性。
