Inequality and Childhood Mortality: a Comparison of England and Wales, 1911, and the United States, 1900
研究提出一个儿童死亡率指数来衡量社会经济福祉和不平等，比较1911年英格兰和威尔士与1900年美国的儿童死亡率与父母职业和收入的关系，发现英格兰和威尔士的社会阶层间死亡率不平等更大。
An index of childhood mortality is proposed as a good measure of socioeconomic well-being and inequality. The index is used to investigate the relationship between childhood mortality and occupation and income of parents. The sources consist of the 1900 United States Census public-use sample and the published 1911 Census of Marriage and Fertility of England and Wales. Results revealed more inequality in mortality and income across social-class groupings in England and Wales than in the United States. The outcome arose more because of relatively higher childhood mortality for white-collar groups in the United States than because of a better situation for blue-collar groups.
