But the absence of a secondary breakdown of such data, like the UK-style, four-fold class analysis (plus examination of patterns of unemployment by ethnicity or religion), makes it hard for social workers, public heath officials, and economic planners to diagnose new problems. Without the necessary data for analysis, public health policies, for example, cannot be directed toward groups that are especially disadvantaged or otherwise at risk.
但是，如果没有像英国模式那样对此类数据进行第二层分析以及四层社会阶层分析（加上按照种族或宗教区分进行的失业模式分析），使得社会工作者、政府卫生官员以及经济规划者很难诊断新的问题。举例说，没有进行分析所必要的数据，就难以针对特别弱势或有危险的群体制定公共卫生政策。
